+Introduction
+------------
+
+The configuration database is collection of configuration options
+organized in a tree structure:
+
+	+- Code maturity level options
+	|  +- Prompt for development and/or incomplete code/drivers
+	+- General setup
+	|  +- Networking support
+	|  +- System V IPC
+	|  +- BSD Process Accounting
+	|  +- Sysctl support
+	+- Loadable module support
+	|  +- Enable loadable module support
+	|     +- Set version information on all module symbols
+	|     +- Kernel module loader
+	+- ...
+
+Every entry has its own dependencies. These dependencies are used
+to determine the visibility of an entry. Any child entry is only
+visible if its parent entry is also visible.
+
+Menu entries
+------------
+
+Most entries define a config option, all other entries help to organize
+them. A single configuration option is defined like this:
+
+config MODVERSIONS
+	bool "Set version information on all module symbols"
+	depends MODULES
+	help
+	  Usually, modules have to be recompiled whenever you switch to a new
+	  kernel.  ...
+
+Every line starts with a key word and can be followed by multiple
+arguments.  "config" starts a new config entry. The following lines
+define attributes for this config option. Attributes can be the type of
+the config option, input prompt, dependencies, help text and default
+values. A config option can be defined multiple times with the same
+name, but every definition can have only a single input prompt and the
+type must not conflict.
+
+Menu attributes
+---------------
+
+A menu entry can have a number of attributes. Not all of them are
+applicable everywhere (see syntax).
+
+- type definition: "bool"/"tristate"/"string"/"hex"/"integer"
+  Every config option must have a type. There are only two basic types:
+  tristate and string, the other types are based on these two. The type
+  definition optionally accepts an input prompt, so these two examples
+  are equivalent:
+
+	bool "Networking support"
+  and
+	bool
+	prompt "Networking support"
+
+- input prompt: "prompt" <prompt> ["if" <expr>]
+  Every menu entry can have at most one prompt, which is used to display
+  to the user. Optionally dependencies only for this prompt can be added
+  with "if".
+
+- default value: "default" <expr> ["if" <expr>]
+  A config option can have any number of default values. If multiple
+  default values are visible, only the first defined one is active.
+  Default values are not limited to the menu entry, where they are
+  defined, this means the default can be defined somewhere else or be
+  overridden by an earlier definition.
+  The default value is only assigned to the config symbol if no other
+  value was set by the user (via the input prompt above). If an input
+  prompt is visible the default value is presented to the user and can
+  be overridden by him.
+  Optionally dependencies only for this default value can be added with
+  "if".
+
+- dependencies: "depends on"/"requires" <expr>
+  This defines a dependency for this menu entry. If multiple
+  dependencies are defined they are connected with '&&'. Dependencies
+  are applied to all other options within this menu entry (which also
+  accept an "if" expression), so these two examples are equivalent:
+
+	bool "foo" if BAR
+	default y if BAR
+  and
+	depends on BAR
+	bool "foo"
+	default y
+
+- reverse dependencies: "select" <symbol> ["if" <expr>]
+  While normal dependencies reduce the upper limit of a symbol (see
+  below), reverse dependencies can be used to force a lower limit of
+  another symbol. The value of the current menu symbol is used as the
+  minimal value <symbol> can be set to. If <symbol> is selected multiple
+  times, the limit is set to the largest selection.
+  Reverse dependencies can only be used with boolean or tristate
+  symbols.
+
+- numerical ranges: "range" <symbol> <symbol> ["if" <expr>]
+  This allows to limit the range of possible input values for integer
+  and hex symbols. The user can only input a value which is larger than
+  or equal to the first symbol and smaller than or equal to the second
+  symbol.
+
+- help text: "help" or "---help---"
+  This defines a help text. The end of the help text is determined by
+  the indentation level, this means it ends at the first line which has
+  a smaller indentation than the first line of the help text.
+  "---help---" and "help" do not differ in behaviour, "---help---" is
+  used to help visually separate configuration logic from help within
+  the file as an aid to developers.
+
+
+Menu dependencies
+-----------------
+
+Dependencies define the visibility of a menu entry and can also reduce
+the input range of tristate symbols. The tristate logic used in the
+expressions uses one more state than normal boolean logic to express the
+module state. Dependency expressions have the following syntax:
+
+<expr> ::= <symbol>                             (1)
+           <symbol> '=' <symbol>                (2)
+           <symbol> '!=' <symbol>               (3)
+           '(' <expr> ')'                       (4)
+           '!' <expr>                           (5)
+           <expr> '&&' <expr>                   (6)
+           <expr> '||' <expr>                   (7)
+
+Expressions are listed in decreasing order of precedence. 
+
+(1) Convert the symbol into an expression. Boolean and tristate symbols
+    are simply converted into the respective expression values. All
+    other symbol types result in 'n'.
+(2) If the values of both symbols are equal, it returns 'y',
+    otherwise 'n'.
+(3) If the values of both symbols are equal, it returns 'n',
+    otherwise 'y'.
+(4) Returns the value of the expression. Used to override precedence.
+(5) Returns the result of (2-/expr/).
+(6) Returns the result of min(/expr/, /expr/).
+(7) Returns the result of max(/expr/, /expr/).
+
+An expression can have a value of 'n', 'm' or 'y' (or 0, 1, 2
+respectively for calculations). A menu entry becomes visible when it's
+expression evaluates to 'm' or 'y'.
+
+There are two types of symbols: constant and nonconstant symbols.
+Nonconstant symbols are the most common ones and are defined with the
+'config' statement. Nonconstant symbols consist entirely of alphanumeric
+characters or underscores.
+Constant symbols are only part of expressions. Constant symbols are
+always surrounded by single or double quotes. Within the quote any
+other character is allowed and the quotes can be escaped using '\'.
+
+Menu structure
+--------------
+
+The position of a menu entry in the tree is determined in two ways. First
+it can be specified explicitly:
+
+menu "Network device support"
+	depends NET
+
+config NETDEVICES
+	...
+
+endmenu
+
+All entries within the "menu" ... "endmenu" block become a submenu of
+"Network device support". All subentries inherit the dependencies from
+the menu entry, e.g. this means the dependency "NET" is added to the
+dependency list of the config option NETDEVICES.
+
+The other way to generate the menu structure is done by analyzing the
+dependencies. If a menu entry somehow depends on the previous entry, it
+can be made a submenu of it. First, the previous (parent) symbol must
+be part of the dependency list and then one of these two conditions
+must be true:
+- the child entry must become invisible, if the parent is set to 'n'
+- the child entry must only be visible, if the parent is visible
+
+config MODULES
+	bool "Enable loadable module support"
+
+config MODVERSIONS
+	bool "Set version information on all module symbols"
+	depends MODULES
+
+comment "module support disabled"
+	depends !MODULES
+
+MODVERSIONS directly depends on MODULES, this means it's only visible if
+MODULES is different from 'n'. The comment on the other hand is always
+visible when MODULES is visible (the (empty) dependency of MODULES is
+also part of the comment dependencies).
+
+
+Kconfig syntax
+--------------
+
+The configuration file describes a series of menu entries, where every
+line starts with a keyword (except help texts). The following keywords
+end a menu entry:
+- config
+- menuconfig
+- choice/endchoice
+- comment
+- menu/endmenu
+- if/endif
+- source
+The first five also start the definition of a menu entry.
+
+config:
+
+	"config" <symbol>
+	<config options>
+
+This defines a config symbol <symbol> and accepts any of above
+attributes as options.
+
+menuconfig:
+	"menuconfig" <symbol>
+	<config options>
+
+This is similiar to the simple config entry above, but it also gives a
+hint to front ends, that all suboptions should be displayed as a
+separate list of options.
+
+choices:
+
+	"choice"
+	<choice options>
+	<choice block>
+	"endchoice"
+
+This defines a choice group and accepts any of above attributes as
+options. A choice can only be of type bool or tristate, while a boolean
+choice only allows a single config entry to be selected, a tristate
+choice also allows any number of config entries to be set to 'm'. This
+can be used if multiple drivers for a single hardware exists and only a
+single driver can be compiled/loaded into the kernel, but all drivers
+can be compiled as modules.
+A choice accepts another option "optional", which allows to set the
+choice to 'n' and no entry needs to be selected.
+
+comment:
+
+	"comment" <prompt>
+	<comment options>
+
+This defines a comment which is displayed to the user during the
+configuration process and is also echoed to the output files. The only
+possible options are dependencies.
+
+menu:
+
+	"menu" <prompt>
+	<menu options>
+	<menu block>
+	"endmenu"
+
+This defines a menu block, see "Menu structure" above for more
+information. The only possible options are dependencies.
+
+if:
+
+	"if" <expr>
+	<if block>
+	"endif"
+
+This defines an if block. The dependency expression <expr> is appended
+to all enclosed menu entries.
+
+source:
+
+	"source" <prompt>
+
+This reads the specified configuration file. This file is always parsed.

+ *  Changes by Clifford Wolf (god@clifford.at)
+ *
+ *  [ 1998-06-13 ]
+ *
+ *    *)  A bugfix for the Page-Down problem
+ *
+ *    *)  Formerly when I used Page Down and Page Up, the cursor would be set 
+ *        to the first position in the menu box.  Now lxdialog is a bit
+ *        smarter and works more like other menu systems (just have a look at
+ *        it).
+ *
+ *    *)  Formerly if I selected something my scrolling would be broken because
+ *        lxdialog is re-invoked by the Menuconfig shell script, can't
+ *        remember the last scrolling position, and just sets it so that the
+ *        cursor is at the bottom of the box.  Now it writes the temporary file
+ *        lxdialog.scrltmp which contains this information. The file is
+ *        deleted by lxdialog if the user leaves a submenu or enters a new
+ *        one, but it would be nice if Menuconfig could make another "rm -f"
+ *        just to be sure.  Just try it out - you will recognise a difference!
+ *
+ *  [ 1998-06-14 ]
+ *
+ *    *)  Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
+ *        and menus change their size on the fly.
+ *
+ *    *)  If for some reason the last scrolling position is not saved by
+ *        lxdialog, it sets the scrolling so that the selected item is in the
+ *        middle of the menu box, not at the bottom.
+ *
+ * 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
+ * Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
+ * This fixes a bug in Menuconfig where using ' ' to descend into menus
+ * would leave mis-synchronized lxdialog.scrltmp files lying around,
+ * fscanf would read in 'scroll', and eventually that value would get used.

+"Overview\n"
+"--------\n"
+"Some features may be built directly into Buildroot.  Some features\n"
+"may be completely removed altogether.  There are also certain\n"
+"parameters which are not really features, but must be\n"
+"entered in as decimal or hexadecimal numbers or possibly text.\n"
+"\n"
+"Menu items beginning with [*] or [ ] represent features\n"
+"configured to be built in or removed respectively.\n"
+"\n"
+"To change any of these features, highlight it with the cursor\n"
+"keys and press <Y> to build it in or <N> to removed it.\n"
+"You may also press the <Space Bar> to cycle\n"
+"through the available options (ie. Y->N->Y).\n"
+"\n"
+"Some additional keyboard hints:\n"
+"\n"
+"Menus\n"
+"----------\n"
+"o  Use the Up/Down arrow keys (cursor keys) to highlight the item\n"
+"   you wish to change or submenu wish to select and press <Enter>.\n"
+"   Submenus are designated by \"--->\".\n"
+"\n"
+"   Shortcut: Press the option's highlighted letter (hotkey).\n"
+"             Pressing a hotkey more than once will sequence\n"
+"             through all visible items which use that hotkey.\n"
+"\n"
+"   You may also use the <PAGE UP> and <PAGE DOWN> keys to scroll\n"
+"   unseen options into view.\n"
+"\n"
+"o  To exit a menu use the cursor keys to highlight the <Exit> button\n"
+"   and press <ENTER>.\n"
+"\n"
+"   Shortcut: Press <ESC><ESC> or <E> or <X> if there is no hotkey\n"
+"             using those letters.  You may press a single <ESC>, but\n"
+"             there is a delayed response which you may find annoying.\n"
+"\n"
+"   Also, the <TAB> and cursor keys will cycle between <Select>,\n"
+"   <Exit> and <Help>\n"
+"\n"
+"o  To get help with an item, use the cursor keys to highlight <Help>\n"
+"   and Press <ENTER>.\n"
+"\n"
+"   Shortcut: Press <H> or <?>.\n"
+"\n"
+"\n"
+"Radiolists  (Choice lists)\n"
+"-----------\n"
+"o  Use the cursor keys to select the option you wish to set and press\n"
+"   <S> or the <SPACE BAR>.\n"
+"\n"
+"   Shortcut: Press the first letter of the option you wish to set then\n"
+"             press <S> or <SPACE BAR>.\n"
+"\n"
+"o  To see available help for the item, use the cursor keys to highlight\n"
+"   <Help> and Press <ENTER>.\n"
+"\n"
+"   Shortcut: Press <H> or <?>.\n"
+"\n"
+"   Also, the <TAB> and cursor keys will cycle between <Select> and\n"

+"\n"
+"\n"
+"Data Entry\n"
+"-----------\n"
+"o  Enter the requested information and press <ENTER>\n"
+"   If you are entering hexadecimal values, it is not necessary to\n"
+"   add the '0x' prefix to the entry.\n"
+"\n"
+"o  For help, use the <TAB> or cursor keys to highlight the help option\n"
+"   and press <ENTER>.  You can try <TAB><H> as well.\n"
+"\n"
+"\n"
+"Text Box    (Help Window)\n"
+"--------\n"
+"o  Use the cursor keys to scroll up/down/left/right.  The VI editor\n"

+"Alternate Configuration Files\n"
+"-----------------------------\n"
+"Menuconfig supports the use of alternate configuration files for\n"
+"those who, for various reasons, find it necessary to switch\n"
+"between different configurations.\n"
+"\n"
+"At the end of the main menu you will find two options.  One is\n"
+"for saving the current configuration to a file of your choosing.\n"
+"The other option is for loading a previously saved alternate\n"
+"configuration.\n"
+"\n"
+"Even if you don't use alternate configuration files, but you\n"
+"find during a Menuconfig session that you have completely messed\n"
+"up your settings, you may use the \"Load Alternate...\" option to\n"
+"restore your previously saved settings from \".config\" without\n"
+"restarting Menuconfig.\n"
+"\n"
+"Other information\n"
+"-----------------\n"
+"If you use Menuconfig in an XTERM window make sure you have your\n"
+"$TERM variable set to point to a xterm definition which supports color.\n"
+"Otherwise, Menuconfig will look rather bad.  Menuconfig will not\n"
+"display correctly in a RXVT window because rxvt displays only one\n"
+"intensity of color, bright.\n"
+"\n"
+"Menuconfig will display larger menus on screens or xterms which are\n"
+"set to display more than the standard 25 row by 80 column geometry.\n"
+"In order for this to work, the \"stty size\" command must be able to\n"
+"display the screen's current row and column geometry.  I STRONGLY\n"
+"RECOMMEND that you make sure you do NOT have the shell variables\n"
+"LINES and COLUMNS exported into your environment.  Some distributions\n"
+"export those variables via /etc/profile.  Some ncurses programs can\n"
+"become confused when those variables (LINES & COLUMNS) don't reflect\n"
+"the true screen size.\n"
+"\n"
+"Optional personality available\n"
+"------------------------------\n"
+"If you prefer to have all of the options listed in a single\n"
+"menu, rather than the default multimenu hierarchy, run the menuconfig\n"
+"with MENUCONFIG_MODE environment variable set to single_menu. Example:\n"
+"\n"
+"make MENUCONFIG_MODE=single_menu menuconfig\n"
+"\n"
+"<Enter> will then unroll the appropriate category, or enfold it if it\n"
+"is already unrolled.\n"
+"\n"
+"Note that this mode can eventually be a little more CPU expensive\n"
+"(especially with a larger number of unrolled categories) than the\n"
+"default mode.\n",

+
+2005-05-12  Paul Eggert  <eggert@CS.UCLA.EDU>
+
+	Explanation for this subtle change:
+
+	From: Paul Eggert <eggert@CS.UCLA.EDU>
+	To: config-patches@gnu.org
+	Subject: config.guess, config.sub misdiagnose write errors
+	
+	config.guess and config.sub sometimes mishandle write errors to
+	stdout: they either ignore the errors, or output invalid
+	diagnostics when they occur.  For a simple (albeit unrealistic)
+	example, on my Solaris 8 (sparc) host, the command "config.guess
+	>&-" exits with status 0; it should exit with status 1, due to the
+	write failure.
+	
+	* config.guess: Don't exit with an explicit exit code of 0.
+	* config.sub: Likewise.

+
+	* config.guess (9000/[34678]??:HP-UX:*:*): Discard stderr of `cc
+	-E -'; HP `cc' emits an error for it but still preprocesses
+	standard input as expected.  Add comment.
+

+--- ABOUT ---
+This isnt a real package, it just exists to easily update the
+config.sub / config.guess files in packages to the latest version
+(since many bundled ones don't support the latest possible targets)
+
+--- HOWTO ---
+To use, just add this to your unpack rule in the package.mk:
+$(CONFIG_UPDATE) $(PACKAGE_DIR)/
+
+--- UPDATE ---
+This is a CVS checkout of the config project, so just run `cvs up` 
+to get the latest config.sub / config.guess files.
+
+A few local customizations are used to support uClibc so you may
+have to make sure they're still needed.  The patches are broken 
+out in the patches/ dir to keep things simple.

+gnuconfig seems intent on only supporting superfluous targets that don't
+represent any real hardware (such as sh2a LE). GCC in its infinite wisdom is
+also incapable of supporting tuning for other variants in a sensible fashion.
+
+As such, we still need to be able to support such useful targets as
+sh2a_nofpueb in order to not only get the byte order right, but also to
+support -m2a-nofpu tuning from the kernel (though we tend to do this through
+-Wa,-isa= instead, as the binutils people do a much better job of not screwing
+up their config code every other day. Way to go config.gcc..).
+
+The fact that the sh variant matching is the ugliest out of any of the other
+architectures doesn't seem to deter GCC folk from their well thought out and
+brilliantly managed config target list.

+Subject: [trunk + 3.4-branch RFA] don't use empic relocs for mips-linuxeh
+
+This patch changes mips-linux to avoid using embedded-pic relocs for
+its eh data.  (Support for generating these for new code is removed in
+current binutils srcs.)
+
+Relating to this, previously, mips-linux and mips64-linux would use
+different representations for their EH data (even for mips64-linux o32
+abi), due to the mips64-linux n32/64 BFDs not supporting the
+embedded-pic relocs.  This was a bug.
+
+For more explanation, see the thread of the URL quoted in the comment
+in linux.h.
+
+
+Tested the same w/ sources of about a week ago for c/c++ for
+mips-linux (native) before/after.  Also verified .o compatibility
+before/after just to be sure.
+
+I'd like this approved for the branch as well, so 3.4.1 will work
+nicely w/ the next major binutils release.
+
+
+thanks,
+
+chris

+Subject: [trunk + 3.4-branch RFA] don't use empic relocs for mips-linuxeh
+
+This patch changes mips-linux to avoid using embedded-pic relocs for
+its eh data.  (Support for generating these for new code is removed in
+current binutils srcs.)
+
+Relating to this, previously, mips-linux and mips64-linux would use
+different representations for their EH data (even for mips64-linux o32
+abi), due to the mips64-linux n32/64 BFDs not supporting the
+embedded-pic relocs.  This was a bug.
+
+For more explanation, see the thread of the URL quoted in the comment
+in linux.h.
+
+
+Tested the same w/ sources of about a week ago for c/c++ for
+mips-linux (native) before/after.  Also verified .o compatibility
+before/after just to be sure.
+
+I'd like this approved for the branch as well, so 3.4.1 will work
+nicely w/ the next major binutils release.
+
+
+thanks,
+
+chris

+[committed] Fix target/17565: asms in delay slots
+
+    * From: Richard Sandiford <rsandifo at redhat dot com>
+    * To: gcc-patches at gcc dot gnu dot org
+    * Date: Mon, 20 Sep 2004 07:55:58 +0100
+    * Subject: [committed] Fix target/17565: asms in delay slots
+
+The MIPS port was allowing asms to be put into delay slots if the
+compiler guesses they are only one instruction long.  This is wrong
+because of the possibility of it containing macros.
+
+The problem can be reproduced as an assembler warning
+in the following testcase:
+
+int foo (int n)
+{
+  register int k asm ("$16") = n;
+  if (k > 0)
+    {
+      bar ();
+      asm ("li %0,0x12345678" : "=r" (k));
+    }
+  return k;
+}
+
+because the multi-instruction asm statement goes into the delay
+slot of the call to bar().
+
+This is reduced from a much more serious linux problem.  Linux is fond
+of using empty asm statements, and since gcc estimates empty asms to be
+one instruction long, they too might be put into delay slots.  This
+actually has the effect of putting the following instruction into the
+delay slot instead.  Since there's no assembler warning, the problem was
+only detected as a run-time failure.
+
+The fix is simple: set the asm value of "can_delay" to "no".
+Tested on mipsisa64-elf, applied to mainline.
+
+This problem goes back to at least 2.95, so it isn't technically a
+regression.  On the other hand, it's the kind of bug that could trigger
+for different types of code in different releases, so I'm sure there's
+a testcase that fails (say) in 3.4 and not in 2.95.  Will probably ask
+Mark for permission to backport to 3.4.

++   FLOAT: Implement a `float', aka SFmode, fp library.  If this is not
++     defined, then this file implements a `double', aka DFmode, fp library.
++   FLOAT_ONLY: Used with FLOAT, to implement a `float' only library, i.e.
++     don't include float->double conversion which requires the double library.
++     This is useful only for machines which can't support doubles, e.g. some
++     8-bit processors.
++   CMPtype: Specify the type that floating point compares should return.
++     This defaults to SItype, aka int.
++   US_SOFTWARE_GOFAST: This makes all entry points use the same names as the
++     US Software goFast library.
++   _DEBUG_BITFLOAT: This makes debugging the code a little easier, by adding
++     two integers to the FLO_union_type.
++   NO_DENORMALS: Disable handling of denormals.
++   NO_NANS: Disable nan and infinity handling
++   SMALL_MACHINE: Useful when operations on QIs and HIs are faster
++     than on an SI */

++   user isn't using long doubles.  However, they may generate an unresolved
++   external to abort if abort is not used by the function, and the stubs
++   are referenced from within libc, since libgcc goes before and after the

++  256 bytes in the data section. Additional divides do
++  not incur additional penalties in the data section.
++
++  Code speed is improved for small divides by about 5x
++  when using this method in the worse case (~9 cycles
++  vs ~45). And in the worse case divides not within the
++  table are penalized by about 10% (~5 cycles vs ~45).
++  However in the typical case the penalty is not as bad
++  because doing the long divide in only 45 cycles is
++  quite optimistic.
++
++  ??? It would be nice to have some benchmarks other
++  than Dhrystone to back this up.
++
++  This bit of expansion is to create this instruction
++  sequence as rtl.

++; ??? This is all really a hack to get Dhrystone to work as fast as possible
++;     things to be fixed:
++;        * let the compiler core handle all of this, for that to work the extra
++;          aliasing needs to be addressed.
++;        * we use three temporary registers for loading and storing to ensure no
++;          ld use stalls, this is excessive, because after the first ld/st only
++;          two are needed. Only two would be needed all the way through if 
++;          we could schedule with other code. Consider:
++;           1  ld $1, 0($src)
++;           2  ld $2, 4($src)
++;           3  ld $3, 8($src)
++;           4  st $1, 0($dest)
++;           5  ld $1, 12($src)
++;           6  st $2, 4($src)
++;           7  etc.
++;          The first store has to wait until 4. If it does not there will be one
++;          cycle of stalling. However, if any other instruction could be placed
++;          between 1 and 4, $3 would not be needed.
++;        * In small we probably don't want to ever do this ourself because there
++;          is no ld use stall.

++## For some targets, invoking GCC in different ways produces objects that
++## can not be linked together.  For example, for some targets GCC produces
++## both big and little endian code.  For these targets, you must arrange
++## for multiple versions of libgcc.a to be compiled, one for each set of
++## incompatible options.  When GCC invokes the linker, it arranges to link
++## in the right version of libgcc.a, based on the command line options
++## used.
++## The MULTILIB_OPTIONS macro lists the set of options for which special
++## versions of libgcc.a must be built.  Write options that are mutually
++## incompatible side by side, separated by a slash.  Write options that may
++## be used together separated by a space.  The build procedure will build
++## all combinations of compatible options.
++##
++## For example, if you set MULTILIB_OPTIONS to m68000/m68020 msoft-float,
++## Makefile will build special versions of libgcc.a using the following
++## sets of options: -m68000, -m68020, -msoft-float, -m68000 -msoft-float,
++## and -m68020 -msoft-float.
++
++MULTILIB_OPTIONS = mno-hw-mul mhw-mulx
++
++## MULTILIB_DIRNAMES
++## If MULTILIB_OPTIONS is used, this variable specifies the directory names
++## that should be used to hold the various libraries.  Write one element in
++## MULTILIB_DIRNAMES for each element in MULTILIB_OPTIONS. If
++## MULTILIB_DIRNAMES is not used, the default value will be
++## MULTILIB_OPTIONS, with all slashes treated as spaces.
++## For example, if MULTILIB_OPTIONS is set to m68000/m68020 msoft-float,
++## then the default value of MULTILIB_DIRNAMES is m68000 m68020
++## msoft-float.  You may specify a different value if you desire a
++## different set of directory names.
++
++# MULTILIB_DIRNAMES =
++
++## MULTILIB_MATCHES
++## Sometimes the same option may be written in two different ways.  If an
++## option is listed in MULTILIB_OPTIONS, GCC needs to know about any
++## synonyms.  In that case, set MULTILIB_MATCHES to a list of items of the
++## form option=option to describe all relevant synonyms.  For example,
++## m68000=mc68000 m68020=mc68020.
++##
++## MULTILIB_EXCEPTIONS
++## Sometimes when there are multiple sets of MULTILIB_OPTIONS being
++## specified, there are combinations that should not be built.  In that
++## case, set MULTILIB_EXCEPTIONS to be all of the switch exceptions in
++## shell case syntax that should not be built.
++## For example, in the PowerPC embedded ABI support, it is not desirable to
++## build libraries compiled with the -mcall-aix option and either of the
++## -fleading-underscore or -mlittle options at the same time.  Therefore
++## MULTILIB_EXCEPTIONS is set to
++##
++## *mcall-aix/*fleading-underscore* *mlittle/*mcall-aix*
++##
++
++MULTILIB_EXCEPTIONS = *mno-hw-mul/*mhw-mulx*
++
++##
++## MULTILIB_EXTRA_OPTS Sometimes it is desirable that when building
++## multiple versions of libgcc.a certain options should always be passed on
++## to the compiler.  In that case, set MULTILIB_EXTRA_OPTS to be the list
++## of options to be used for all builds.

++
++These built-in functions are available for the Altera Nios II
++family of processors.
++
++The following built-in functions are always available.  They
++all generate the machine instruction that is part of the name.
++
++@example
++int __builtin_ldbio (volatile const void *)
++int __builtin_ldbuio (volatile const void *)

++
++The following built-in functions are always available.  They
++all generate a Nios II Custom Instruction. The name of the 
++function represents the types that the function takes and 
++returns. The letter before the @code{n} is the return type
++or void if absent. The @code{n} represnts the first parameter
++to all the custom instructions, the custom instruction number.
++The two letters after the @code{n} represent the up to two 
++parameters to the function.
++
++The letters reprsent the following data types:
++@table @code
++@item <no letter>
++@code{void} for return type and no parameter for parameter types.
++
++@item i
++@code{int} for return type and parameter type
++
++@item f

+# Submitted:
+#
+# Dimitry Andric <dimitry@andric.com>, 2004-05-01
+#
+# Description:
+#
+# Nicholas Pitre released this patch for gcc soft-float support here: 
+# http://lists.arm.linux.org.uk/pipermail/linux-arm/2003-October/006436.html
+#
+# This version has been adapted to work with gcc 3.4.0.
+#
+# The original patch doesn't distinguish between softfpa and softvfp modes
+# in the way Nicholas Pitre probably meant.  His description is:
+#
+# "Default is to use APCS-32 mode with soft-vfp.  The old Linux default for
+# floats can be achieved with -mhard-float or with the configure
+# --with-float=hard option.  If -msoft-float or --with-float=soft is used then
+# software float support will be used just like the default but with the legacy
+# big endian word ordering for double float representation instead."
+#
+# Which means the following:
+#
+# * If you compile without -mhard-float or -msoft-float, you should get
+#   software floating point, using the VFP format.  The produced object file
+#   should have these flags in its header:
+#
+#     private flags = 600: [APCS-32] [VFP float format] [software FP]
+#
+# * If you compile with -mhard-float, you should get hardware floating point,
+#   which always uses the FPA format.  Object file header flags should be:
+#
+#     private flags = 0: [APCS-32] [FPA float format]
+#
+# * If you compile with -msoft-float, you should get software floating point,
+#   using the FPA format.  This is done for compatibility reasons with many
+#   existing distributions.  Object file header flags should be:
+#
+#     private flags = 200: [APCS-32] [FPA float format] [software FP]
+#
+# The original patch from Nicholas Pitre contained the following constructs:
+#
+#   #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
+#     %{mhard-float:-mfpu=fpa} \
+#     %{!mhard-float: %{msoft-float:-mfpu=softfpa;:-mfpu=softvfp}}"
+#
+# However, gcc doesn't accept this ";:" notation, used in the 3rd line.  This
+# is probably the reason Robert Schwebel modified it to:
+#
+#   #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
+#     %{mhard-float:-mfpu=fpa} \
+#     %{!mhard-float: %{msoft-float:-mfpu=softfpa -mfpu=softvfp}}"
+#
+# But this causes the following behaviour:
+#
+# * If you compile without -mhard-float or -msoft-float, the compiler generates
+#   software floating point instructions, but *nothing* is passed to the
+#   assembler, which results in an object file which has flags:
+#
+#     private flags = 0: [APCS-32] [FPA float format]
+#
+#   This is not correct!
+#
+# * If you compile with -mhard-float, the compiler generates hardware floating
+#   point instructions, and passes "-mfpu=fpa" to the assembler, which results
+#   in an object file which has the same flags as in the previous item, but now
+#   those *are* correct.
+#    
+# * If you compile with -msoft-float, the compiler generates software floating
+#   point instructions, and passes "-mfpu=softfpa -mfpu=softvfp" (in that
+#   order) to the assembler, which results in an object file with flags:
+#
+#   private flags = 600: [APCS-32] [VFP float format] [software FP]
+#
+#   This is not correct, because the last "-mfpu=" option on the assembler
+#   command line determines the actual FPU convention used (which should be FPA
+#   in this case).
+#
+# Therefore, I modified this patch to get the desired behaviour.  Every
+# instance of the notation:
+#
+#   %{msoft-float:-mfpu=softfpa -mfpu=softvfp}
+#
+# was changed to:
+#
+#   %{msoft-float:-mfpu=softfpa} %{!msoft-float:-mfpu=softvfp}
+#
+# I also did the following:
+# 
+# * Modified all TARGET_DEFAULT macros I could find to include ARM_FLAG_VFP, to
+#   be consistent with Nicholas' original patch.
+# * Removed any "msoft-float" or "mhard-float" from all MULTILIB_DEFAULTS
+#   macros I could find.  I think that if you compile without any options, you
+#   would like to get the defaults. :)
+# * Removed the extra -lfloat option from LIBGCC_SPEC, since it isn't needed
+#   anymore.  (The required functions are now in libgcc.)

++; ??? This is all really a hack to get Dhrystone to work as fast as possible
++;     things to be fixed:
++;        * let the compiler core handle all of this, for that to work the extra
++;          aliasing needs to be addressed.
++;        * we use three temporary registers for loading and storing to ensure no
++;          ld use stalls, this is excessive, because after the first ld/st only
++;          two are needed. Only two would be needed all the way through if 
++;          we could schedule with other code. Consider:
++;           1  ld $1, 0($src)
++;           2  ld $2, 4($src)
++;           3  ld $3, 8($src)
++;           4  st $1, 0($dest)
++;           5  ld $1, 12($src)
++;           6  st $2, 4($src)
++;           7  etc.
++;          The first store has to wait until 4. If it does not there will be one
++;          cycle of stalling. However, if any other instruction could be placed
++;          between 1 and 4, $3 would not be needed.
++;        * In small we probably don't want to ever do this ourself because there
++;          is no ld use stall.

++## MULTILIB_OPTIONS
++## For some targets, invoking GCC in different ways produces objects that
++## can not be linked together.  For example, for some targets GCC produces
++## both big and little endian code.  For these targets, you must arrange
++## for multiple versions of libgcc.a to be compiled, one for each set of
++## incompatible options.  When GCC invokes the linker, it arranges to link
++## in the right version of libgcc.a, based on the command line options
++## used.
++## The MULTILIB_OPTIONS macro lists the set of options for which special
++## versions of libgcc.a must be built.  Write options that are mutually
++## incompatible side by side, separated by a slash.  Write options that may
++## be used together separated by a space.  The build procedure will build
++## all combinations of compatible options.
++##
++## For example, if you set MULTILIB_OPTIONS to m68000/m68020 msoft-float,
++## Makefile will build special versions of libgcc.a using the following
++## sets of options: -m68000, -m68020, -msoft-float, -m68000 -msoft-float,
++## and -m68020 -msoft-float.
++
++MULTILIB_OPTIONS = mno-hw-mul mhw-mulx
++
++## MULTILIB_DIRNAMES
++## If MULTILIB_OPTIONS is used, this variable specifies the directory names
++## that should be used to hold the various libraries.  Write one element in
++## MULTILIB_DIRNAMES for each element in MULTILIB_OPTIONS. If
++## MULTILIB_DIRNAMES is not used, the default value will be
++## MULTILIB_OPTIONS, with all slashes treated as spaces.
++## For example, if MULTILIB_OPTIONS is set to m68000/m68020 msoft-float,
++## then the default value of MULTILIB_DIRNAMES is m68000 m68020
++## msoft-float.  You may specify a different value if you desire a
++## different set of directory names.
++
++# MULTILIB_DIRNAMES =
++
++## MULTILIB_MATCHES
++## Sometimes the same option may be written in two different ways.  If an
++## option is listed in MULTILIB_OPTIONS, GCC needs to know about any
++## synonyms.  In that case, set MULTILIB_MATCHES to a list of items of the
++## form option=option to describe all relevant synonyms.  For example,
++## m68000=mc68000 m68020=mc68020.
++##
++## MULTILIB_EXCEPTIONS
++## Sometimes when there are multiple sets of MULTILIB_OPTIONS being
++## specified, there are combinations that should not be built.  In that
++## case, set MULTILIB_EXCEPTIONS to be all of the switch exceptions in
++## shell case syntax that should not be built.
++## For example, in the PowerPC embedded ABI support, it is not desirable to
++## build libraries compiled with the -mcall-aix option and either of the
++## -fleading-underscore or -mlittle options at the same time.  Therefore
++## MULTILIB_EXCEPTIONS is set to
++##
++## *mcall-aix/*fleading-underscore* *mlittle/*mcall-aix*
++##
++
++MULTILIB_EXCEPTIONS = *mno-hw-mul/*mhw-mulx*
++
++##
++## MULTILIB_EXTRA_OPTS Sometimes it is desirable that when building
++## multiple versions of libgcc.a certain options should always be passed on
++## to the compiler.  In that case, set MULTILIB_EXTRA_OPTS to be the list
++## of options to be used for all builds.

++
++These built-in functions are available for the Altera Nios II
++family of processors.
++
++The following built-in functions are always available.  They
++all generate the machine instruction that is part of the name.

++The following built-in functions are always available.  They
++all generate a Nios II Custom Instruction. The name of the 
++function represents the types that the function takes and 
++returns. The letter before the @code{n} is the return type
++or void if absent. The @code{n} represnts the first parameter
++to all the custom instructions, the custom instruction number.
++The two letters after the @code{n} represent the up to two 
++parameters to the function.
++
++The letters reprsent the following data types:
++@table @code
++@item <no letter>
++@code{void} for return type and no parameter for parameter types.
++
++@item i
++@code{int} for return type and parameter type

+# Description:
+#
+# Nicholas Pitre released this patch for gcc soft-float support here: 
+# http://lists.arm.linux.org.uk/pipermail/linux-arm/2003-October/006436.html
+#
+# This version has been adapted to work with gcc 3.4.0.
+#
+# The original patch doesn't distinguish between softfpa and softvfp modes
+# in the way Nicholas Pitre probably meant.  His description is:
+#
+# "Default is to use APCS-32 mode with soft-vfp.  The old Linux default for
+# floats can be achieved with -mhard-float or with the configure
+# --with-float=hard option.  If -msoft-float or --with-float=soft is used then
+# software float support will be used just like the default but with the legacy
+# big endian word ordering for double float representation instead."
+#
+# Which means the following:
+#
+# * If you compile without -mhard-float or -msoft-float, you should get
+#   software floating point, using the VFP format.  The produced object file
+#   should have these flags in its header:
+#
+#     private flags = 600: [APCS-32] [VFP float format] [software FP]
+#
+# * If you compile with -mhard-float, you should get hardware floating point,
+#   which always uses the FPA format.  Object file header flags should be:
+#
+#     private flags = 0: [APCS-32] [FPA float format]
+#
+# * If you compile with -msoft-float, you should get software floating point,
+#   using the FPA format.  This is done for compatibility reasons with many
+#   existing distributions.  Object file header flags should be:
+#
+#     private flags = 200: [APCS-32] [FPA float format] [software FP]
+#
+# The original patch from Nicholas Pitre contained the following constructs:
+#
+#   #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
+#     %{mhard-float:-mfpu=fpa} \
+#     %{!mhard-float: %{msoft-float:-mfpu=softfpa;:-mfpu=softvfp}}"
+#
+# However, gcc doesn't accept this ";:" notation, used in the 3rd line.  This
+# is probably the reason Robert Schwebel modified it to:
+#
+#   #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
+#     %{mhard-float:-mfpu=fpa} \
+#     %{!mhard-float: %{msoft-float:-mfpu=softfpa -mfpu=softvfp}}"
+#
+# But this causes the following behaviour:
+#
+# * If you compile without -mhard-float or -msoft-float, the compiler generates
+#   software floating point instructions, but *nothing* is passed to the
+#   assembler, which results in an object file which has flags:
+#
+#     private flags = 0: [APCS-32] [FPA float format]
+#
+#   This is not correct!
+#
+# * If you compile with -mhard-float, the compiler generates hardware floating
+#   point instructions, and passes "-mfpu=fpa" to the assembler, which results
+#   in an object file which has the same flags as in the previous item, but now
+#   those *are* correct.
+#    
+# * If you compile with -msoft-float, the compiler generates software floating
+#   point instructions, and passes "-mfpu=softfpa -mfpu=softvfp" (in that
+#   order) to the assembler, which results in an object file with flags:
+#
+#   private flags = 600: [APCS-32] [VFP float format] [software FP]
+#
+#   This is not correct, because the last "-mfpu=" option on the assembler
+#   command line determines the actual FPU convention used (which should be FPA
+#   in this case).
+#
+# Therefore, I modified this patch to get the desired behaviour.  Every
+# instance of the notation:
+#
+#   %{msoft-float:-mfpu=softfpa -mfpu=softvfp}
+#
+# was changed to:
+#
+#   %{msoft-float:-mfpu=softfpa} %{!msoft-float:-mfpu=softvfp}
+#
+# I also did the following:
+# 
+# * Modified all TARGET_DEFAULT macros I could find to include ARM_FLAG_VFP, to
+#   be consistent with Nicholas' original patch.
+# * Removed any "msoft-float" or "mhard-float" from all MULTILIB_DEFAULTS
+#   macros I could find.  I think that if you compile without any options, you
+#   would like to get the defaults. :)
+# * Removed the extra -lfloat option from LIBGCC_SPEC, since it isn't needed
+#   anymore.  (The required functions are now in libgcc.)

++   FLOAT_ONLY: Used with FLOAT, to implement a `float' only library, i.e.
++     don't include float->double conversion which requires the double library.
++     This is useful only for machines which can't support doubles, e.g. some

++   CMPtype: Specify the type that floating point compares should return.
++     This defaults to SItype, aka int.
++   US_SOFTWARE_GOFAST: This makes all entry points use the same names as the
++     US Software goFast library.
++   _DEBUG_BITFLOAT: This makes debugging the code a little easier, by adding
++     two integers to the FLO_union_type.
++   NO_DENORMALS: Disable handling of denormals.
++   NO_NANS: Disable nan and infinity handling
++   SMALL_MACHINE: Useful when operations on QIs and HIs are faster

++;;	Different CC modes are used, based on what type of branch is

++## MULTILIB_OPTIONS
++## For some targets, invoking GCC in different ways produces objects that
++## can not be linked together.  For example, for some targets GCC produces
++## both big and little endian code.  For these targets, you must arrange
++## for multiple versions of libgcc.a to be compiled, one for each set of
++## incompatible options.  When GCC invokes the linker, it arranges to link
++## in the right version of libgcc.a, based on the command line options
++## used.
++## The MULTILIB_OPTIONS macro lists the set of options for which special
++## versions of libgcc.a must be built.  Write options that are mutually
++## incompatible side by side, separated by a slash.  Write options that may
++## be used together separated by a space.  The build procedure will build
++## all combinations of compatible options.
++##
++## For example, if you set MULTILIB_OPTIONS to m68000/m68020 msoft-float,
++## Makefile will build special versions of libgcc.a using the following
++## sets of options: -m68000, -m68020, -msoft-float, -m68000 -msoft-float,
++## and -m68020 -msoft-float.
++
++MULTILIB_OPTIONS = mno-hw-mul mhw-mulx
++
++## MULTILIB_DIRNAMES
++## If MULTILIB_OPTIONS is used, this variable specifies the directory names
++## that should be used to hold the various libraries.  Write one element in
++## MULTILIB_DIRNAMES for each element in MULTILIB_OPTIONS. If
++## MULTILIB_DIRNAMES is not used, the default value will be
++## MULTILIB_OPTIONS, with all slashes treated as spaces.
++## For example, if MULTILIB_OPTIONS is set to m68000/m68020 msoft-float,
++## then the default value of MULTILIB_DIRNAMES is m68000 m68020
++## msoft-float.  You may specify a different value if you desire a
++## different set of directory names.
++
++# MULTILIB_DIRNAMES =
++
++## MULTILIB_MATCHES
++## Sometimes the same option may be written in two different ways.  If an
++## option is listed in MULTILIB_OPTIONS, GCC needs to know about any
++## synonyms.  In that case, set MULTILIB_MATCHES to a list of items of the
++## form option=option to describe all relevant synonyms.  For example,
++## m68000=mc68000 m68020=mc68020.
++##
++## MULTILIB_EXCEPTIONS
++## Sometimes when there are multiple sets of MULTILIB_OPTIONS being
++## specified, there are combinations that should not be built.  In that
++## case, set MULTILIB_EXCEPTIONS to be all of the switch exceptions in
++## shell case syntax that should not be built.
++## For example, in the PowerPC embedded ABI support, it is not desirable to
++## build libraries compiled with the -mcall-aix option and either of the
++## -fleading-underscore or -mlittle options at the same time.  Therefore
++## MULTILIB_EXCEPTIONS is set to
++##
++## *mcall-aix/*fleading-underscore* *mlittle/*mcall-aix*
++##
++
++MULTILIB_EXCEPTIONS = *mno-hw-mul/*mhw-mulx*
++
++##
++## MULTILIB_EXTRA_OPTS Sometimes it is desirable that when building
++## multiple versions of libgcc.a certain options should always be passed on
++## to the compiler.  In that case, set MULTILIB_EXTRA_OPTS to be the list
++## of options to be used for all builds.

++@subsection Altera Nios II Built-in Functions
++
++These built-in functions are available for the Altera Nios II
++family of processors.
++
++The following built-in functions are always available.  They
++all generate the machine instruction that is part of the name.
++
++@example
++int __builtin_ldbio (volatile const void *)
++int __builtin_ldbuio (volatile const void *)
++int __builtin_ldhio (volatile const void *)
++int __builtin_ldhuio (volatile const void *)
++int __builtin_ldwio (volatile const void *)
++void __builtin_stbio (volatile void *, int)
++void __builtin_sthio (volatile void *, int)
++void __builtin_stwio (volatile void *, int)
++void __builtin_sync (void)
++int __builtin_rdctl (int) 
++void __builtin_wrctl (int, int)
++@end example
++
++The following built-in functions are always available.  They
++all generate a Nios II Custom Instruction. The name of the 
++function represents the types that the function takes and 
++returns. The letter before the @code{n} is the return type
++or void if absent. The @code{n} represnts the first parameter
++to all the custom instructions, the custom instruction number.
++The two letters after the @code{n} represent the up to two 
++parameters to the function.
++
++The letters reprsent the following data types:
++@table @code
++@item <no letter>
++@code{void} for return type and no parameter for parameter types.
++
++@item i
++@code{int} for return type and parameter type
++
++@item f
++@code{float} for return type and parameter type
++
++@item p
++@code{void *} for return type and parameter type
++
++@end table
++
++And the function names are:
++@example

+#
+# Submitted:
+#
+# Dimitry Andric <dimitry@andric.com>, 2004-05-01
+#
+# Description:
+#
+# Nicholas Pitre released this patch for gcc soft-float support here: 
+# http://lists.arm.linux.org.uk/pipermail/linux-arm/2003-October/006436.html
+#
+# This version has been adapted to work with gcc 3.4.0.
+#
+# The original patch doesn't distinguish between softfpa and softvfp modes
+# in the way Nicholas Pitre probably meant.  His description is:
+#
+# "Default is to use APCS-32 mode with soft-vfp.  The old Linux default for
+# floats can be achieved with -mhard-float or with the configure
+# --with-float=hard option.  If -msoft-float or --with-float=soft is used then
+# software float support will be used just like the default but with the legacy
+# big endian word ordering for double float representation instead."
+#
+# Which means the following:
+#
+# * If you compile without -mhard-float or -msoft-float, you should get
+#   software floating point, using the VFP format.  The produced object file
+#   should have these flags in its header:
+#
+#     private flags = 600: [APCS-32] [VFP float format] [software FP]
+#
+# * If you compile with -mhard-float, you should get hardware floating point,
+#   which always uses the FPA format.  Object file header flags should be:
+#
+#     private flags = 0: [APCS-32] [FPA float format]
+#
+# * If you compile with -msoft-float, you should get software floating point,
+#   using the FPA format.  This is done for compatibility reasons with many
+#   existing distributions.  Object file header flags should be:
+#
+#     private flags = 200: [APCS-32] [FPA float format] [software FP]
+#
+# The original patch from Nicholas Pitre contained the following constructs:
+#
+#   #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
+#     %{mhard-float:-mfpu=fpa} \
+#     %{!mhard-float: %{msoft-float:-mfpu=softfpa;:-mfpu=softvfp}}"
+#
+# However, gcc doesn't accept this ";:" notation, used in the 3rd line.  This
+# is probably the reason Robert Schwebel modified it to:
+#
+#   #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
+#     %{mhard-float:-mfpu=fpa} \
+#     %{!mhard-float: %{msoft-float:-mfpu=softfpa -mfpu=softvfp}}"
+#
+# But this causes the following behaviour:
+#
+# * If you compile without -mhard-float or -msoft-float, the compiler generates
+#   software floating point instructions, but *nothing* is passed to the
+#   assembler, which results in an object file which has flags:
+#
+#     private flags = 0: [APCS-32] [FPA float format]
+#
+#   This is not correct!
+#
+# * If you compile with -mhard-float, the compiler generates hardware floating
+#   point instructions, and passes "-mfpu=fpa" to the assembler, which results
+#   in an object file which has the same flags as in the previous item, but now
+#   those *are* correct.
+#    
+# * If you compile with -msoft-float, the compiler generates software floating
+#   point instructions, and passes "-mfpu=softfpa -mfpu=softvfp" (in that
+#   order) to the assembler, which results in an object file with flags:
+#
+#   private flags = 600: [APCS-32] [VFP float format] [software FP]
+#
+#   This is not correct, because the last "-mfpu=" option on the assembler
+#   command line determines the actual FPU convention used (which should be FPA
+#   in this case).
+#
+# Therefore, I modified this patch to get the desired behaviour.  Every
+# instance of the notation:
+#
+#   %{msoft-float:-mfpu=softfpa -mfpu=softvfp}
+#
+# was changed to:
+#
+#   %{msoft-float:-mfpu=softfpa} %{!msoft-float:-mfpu=softvfp}
+#
+# I also did the following:
+# 
+# * Modified all TARGET_DEFAULT macros I could find to include ARM_FLAG_VFP, to
+#   be consistent with Nicholas' original patch.
+# * Removed any "msoft-float" or "mhard-float" from all MULTILIB_DEFAULTS
+#   macros I could find.  I think that if you compile without any options, you
+#   would like to get the defaults. :)
+# * Removed the extra -lfloat option from LIBGCC_SPEC, since it isn't needed
+#   anymore.  (The required functions are now in libgcc.)

++; ??? This is all really a hack to get Dhrystone to work as fast as possible
++;     things to be fixed:
++;        * let the compiler core handle all of this, for that to work the extra
++;          aliasing needs to be addressed.
++;        * we use three temporary registers for loading and storing to ensure no
++;          ld use stalls, this is excessive, because after the first ld/st only
++;          two are needed. Only two would be needed all the way through if 
++;          we could schedule with other code. Consider:
++;           1  ld $1, 0($src)
++;           2  ld $2, 4($src)
++;           3  ld $3, 8($src)
++;           4  st $1, 0($dest)
++;           5  ld $1, 12($src)
++;           6  st $2, 4($src)
++;           7  etc.
++;          The first store has to wait until 4. If it does not there will be one
++;          cycle of stalling. However, if any other instruction could be placed
++;          between 1 and 4, $3 would not be needed.
++;        * In small we probably don't want to ever do this ourself because there
++;          is no ld use stall.

++## MULTILIB_OPTIONS
++## For some targets, invoking GCC in different ways produces objects that
++## can not be linked together.  For example, for some targets GCC produces
++## both big and little endian code.  For these targets, you must arrange
++## for multiple versions of libgcc.a to be compiled, one for each set of
++## incompatible options.  When GCC invokes the linker, it arranges to link
++## in the right version of libgcc.a, based on the command line options
++## used.
++## The MULTILIB_OPTIONS macro lists the set of options for which special
++## versions of libgcc.a must be built.  Write options that are mutually
++## incompatible side by side, separated by a slash.  Write options that may
++## be used together separated by a space.  The build procedure will build
++## all combinations of compatible options.
++##
++## For example, if you set MULTILIB_OPTIONS to m68000/m68020 msoft-float,
++## Makefile will build special versions of libgcc.a using the following
++## sets of options: -m68000, -m68020, -msoft-float, -m68000 -msoft-float,
++## and -m68020 -msoft-float.
++
++MULTILIB_OPTIONS = mno-hw-mul mhw-mulx
++
++## MULTILIB_DIRNAMES
++## If MULTILIB_OPTIONS is used, this variable specifies the directory names
++## that should be used to hold the various libraries.  Write one element in
++## MULTILIB_DIRNAMES for each element in MULTILIB_OPTIONS. If
++## MULTILIB_DIRNAMES is not used, the default value will be
++## MULTILIB_OPTIONS, with all slashes treated as spaces.
++## For example, if MULTILIB_OPTIONS is set to m68000/m68020 msoft-float,
++## then the default value of MULTILIB_DIRNAMES is m68000 m68020
++## msoft-float.  You may specify a different value if you desire a
++## different set of directory names.
++
++# MULTILIB_DIRNAMES =
++
++## MULTILIB_MATCHES
++## Sometimes the same option may be written in two different ways.  If an
++## option is listed in MULTILIB_OPTIONS, GCC needs to know about any
++## synonyms.  In that case, set MULTILIB_MATCHES to a list of items of the
++## form option=option to describe all relevant synonyms.  For example,
++## m68000=mc68000 m68020=mc68020.
++##
++## MULTILIB_EXCEPTIONS
++## Sometimes when there are multiple sets of MULTILIB_OPTIONS being
++## specified, there are combinations that should not be built.  In that
++## case, set MULTILIB_EXCEPTIONS to be all of the switch exceptions in
++## shell case syntax that should not be built.
++## For example, in the PowerPC embedded ABI support, it is not desirable to
++## build libraries compiled with the -mcall-aix option and either of the
++## -fleading-underscore or -mlittle options at the same time.  Therefore
++## MULTILIB_EXCEPTIONS is set to
++##
++## *mcall-aix/*fleading-underscore* *mlittle/*mcall-aix*
++##
++
++MULTILIB_EXCEPTIONS = *mno-hw-mul/*mhw-mulx*
++
++##
++## MULTILIB_EXTRA_OPTS Sometimes it is desirable that when building
++## multiple versions of libgcc.a certain options should always be passed on
++## to the compiler.  In that case, set MULTILIB_EXTRA_OPTS to be the list
++## of options to be used for all builds.

++The following built-in functions are always available.  They
++all generate a Nios II Custom Instruction. The name of the 
++function represents the types that the function takes and 
++returns. The letter before the @code{n} is the return type
++or void if absent. The @code{n} represnts the first parameter
++to all the custom instructions, the custom instruction number.
++The two letters after the @code{n} represent the up to two 
++parameters to the function.
++
++The letters reprsent the following data types:

+# Description:
+#
+# Nicholas Pitre released this patch for gcc soft-float support here: 
+# http://lists.arm.linux.org.uk/pipermail/linux-arm/2003-October/006436.html
+#
+# This version has been adapted to work with gcc 3.4.0.
+#
+# The original patch doesn't distinguish between softfpa and softvfp modes
+# in the way Nicholas Pitre probably meant.  His description is:
+#
+# "Default is to use APCS-32 mode with soft-vfp.  The old Linux default for
+# floats can be achieved with -mhard-float or with the configure
+# --with-float=hard option.  If -msoft-float or --with-float=soft is used then
+# software float support will be used just like the default but with the legacy
+# big endian word ordering for double float representation instead."
+#
+# Which means the following:
+#
+# * If you compile without -mhard-float or -msoft-float, you should get
+#   software floating point, using the VFP format.  The produced object file
+#   should have these flags in its header:
+#
+#     private flags = 600: [APCS-32] [VFP float format] [software FP]
+#
+# * If you compile with -mhard-float, you should get hardware floating point,
+#   which always uses the FPA format.  Object file header flags should be:
+#
+#     private flags = 0: [APCS-32] [FPA float format]
+#
+# * If you compile with -msoft-float, you should get software floating point,
+#   using the FPA format.  This is done for compatibility reasons with many
+#   existing distributions.  Object file header flags should be:
+#
+#     private flags = 200: [APCS-32] [FPA float format] [software FP]
+#
+# The original patch from Nicholas Pitre contained the following constructs:
+#
+#   #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
+#     %{mhard-float:-mfpu=fpa} \
+#     %{!mhard-float: %{msoft-float:-mfpu=softfpa;:-mfpu=softvfp}}"
+#
+# However, gcc doesn't accept this ";:" notation, used in the 3rd line.  This
+# is probably the reason Robert Schwebel modified it to:
+#
+#   #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
+#     %{mhard-float:-mfpu=fpa} \
+#     %{!mhard-float: %{msoft-float:-mfpu=softfpa -mfpu=softvfp}}"
+#
+# But this causes the following behaviour:
+#
+# * If you compile without -mhard-float or -msoft-float, the compiler generates
+#   software floating point instructions, but *nothing* is passed to the
+#   assembler, which results in an object file which has flags:
+#
+#     private flags = 0: [APCS-32] [FPA float format]
+#
+#   This is not correct!
+#
+# * If you compile with -mhard-float, the compiler generates hardware floating
+#   point instructions, and passes "-mfpu=fpa" to the assembler, which results
+#   in an object file which has the same flags as in the previous item, but now
+#   those *are* correct.
+#    
+# * If you compile with -msoft-float, the compiler generates software floating
+#   point instructions, and passes "-mfpu=softfpa -mfpu=softvfp" (in that
+#   order) to the assembler, which results in an object file with flags:
+#
+#   private flags = 600: [APCS-32] [VFP float format] [software FP]
+#
+#   This is not correct, because the last "-mfpu=" option on the assembler
+#   command line determines the actual FPU convention used (which should be FPA
+#   in this case).
+#
+# Therefore, I modified this patch to get the desired behaviour.  Every
+# instance of the notation:
+#
+#   %{msoft-float:-mfpu=softfpa -mfpu=softvfp}
+#
+# was changed to:
+#
+#   %{msoft-float:-mfpu=softfpa} %{!msoft-float:-mfpu=softvfp}
+#
+# I also did the following:
+# 
+# * Modified all TARGET_DEFAULT macros I could find to include ARM_FLAG_VFP, to
+#   be consistent with Nicholas' original patch.
+# * Removed any "msoft-float" or "mhard-float" from all MULTILIB_DEFAULTS
+#   macros I could find.  I think that if you compile without any options, you
+#   would like to get the defaults. :)
+# * Removed the extra -lfloat option from LIBGCC_SPEC, since it isn't needed
+#   anymore.  (The required functions are now in libgcc.)

++   FLOAT_ONLY: Used with FLOAT, to implement a `float' only library, i.e.
++     don't include float->double conversion which requires the double library.
++     This is useful only for machines which can't support doubles, e.g. some

++   CMPtype: Specify the type that floating point compares should return.
++     This defaults to SItype, aka int.
++   US_SOFTWARE_GOFAST: This makes all entry points use the same names as the
++     US Software goFast library.
++   _DEBUG_BITFLOAT: This makes debugging the code a little easier, by adding
++     two integers to the FLO_union_type.
++   NO_DENORMALS: Disable handling of denormals.
++   NO_NANS: Disable nan and infinity handling
++   SMALL_MACHINE: Useful when operations on QIs and HIs are faster

++; ??? This is all really a hack to get Dhrystone to work as fast as possible
++;     things to be fixed:
++;        * let the compiler core handle all of this, for that to work the extra
++;          aliasing needs to be addressed.
++;        * we use three temporary registers for loading and storing to ensure no
++;          ld use stalls, this is excessive, because after the first ld/st only
++;          two are needed. Only two would be needed all the way through if 
++;          we could schedule with other code. Consider:
++;           1  ld $1, 0($src)
++;           2  ld $2, 4($src)
++;           3  ld $3, 8($src)
++;           4  st $1, 0($dest)
++;           5  ld $1, 12($src)
++;           6  st $2, 4($src)
++;           7  etc.
++;          The first store has to wait until 4. If it does not there will be one
++;          cycle of stalling. However, if any other instruction could be placed
++;          between 1 and 4, $3 would not be needed.
++;        * In small we probably don't want to ever do this ourself because there
++;          is no ld use stall.

++##
++## MULTILIB_OPTIONS
++## For some targets, invoking GCC in different ways produces objects that
++## can not be linked together.  For example, for some targets GCC produces
++## both big and little endian code.  For these targets, you must arrange
++## for multiple versions of libgcc.a to be compiled, one for each set of
++## incompatible options.  When GCC invokes the linker, it arranges to link
++## in the right version of libgcc.a, based on the command line options
++## used.
++## The MULTILIB_OPTIONS macro lists the set of options for which special
++## versions of libgcc.a must be built.  Write options that are mutually
++## incompatible side by side, separated by a slash.  Write options that may
++## be used together separated by a space.  The build procedure will build
++## all combinations of compatible options.
++##
++## For example, if you set MULTILIB_OPTIONS to m68000/m68020 msoft-float,
++## Makefile will build special versions of libgcc.a using the following
++## sets of options: -m68000, -m68020, -msoft-float, -m68000 -msoft-float,
++## and -m68020 -msoft-float.
++
++MULTILIB_OPTIONS = mno-hw-mul mhw-mulx
++
++## MULTILIB_DIRNAMES
++## If MULTILIB_OPTIONS is used, this variable specifies the directory names
++## that should be used to hold the various libraries.  Write one element in
++## MULTILIB_DIRNAMES for each element in MULTILIB_OPTIONS. If
++## MULTILIB_DIRNAMES is not used, the default value will be
++## MULTILIB_OPTIONS, with all slashes treated as spaces.
++## For example, if MULTILIB_OPTIONS is set to m68000/m68020 msoft-float,
++## then the default value of MULTILIB_DIRNAMES is m68000 m68020
++## msoft-float.  You may specify a different value if you desire a
++## different set of directory names.
++
++# MULTILIB_DIRNAMES =
++
++## MULTILIB_MATCHES
++## Sometimes the same option may be written in two different ways.  If an
++## option is listed in MULTILIB_OPTIONS, GCC needs to know about any
++## synonyms.  In that case, set MULTILIB_MATCHES to a list of items of the
++## form option=option to describe all relevant synonyms.  For example,
++## m68000=mc68000 m68020=mc68020.
++##
++## MULTILIB_EXCEPTIONS
++## Sometimes when there are multiple sets of MULTILIB_OPTIONS being
++## specified, there are combinations that should not be built.  In that
++## case, set MULTILIB_EXCEPTIONS to be all of the switch exceptions in
++## shell case syntax that should not be built.
++## For example, in the PowerPC embedded ABI support, it is not desirable to
++## build libraries compiled with the -mcall-aix option and either of the
++## -fleading-underscore or -mlittle options at the same time.  Therefore
++## MULTILIB_EXCEPTIONS is set to
++##
++## *mcall-aix/*fleading-underscore* *mlittle/*mcall-aix*
++##
++
++MULTILIB_EXCEPTIONS = *mno-hw-mul/*mhw-mulx*
++
++##
++## MULTILIB_EXTRA_OPTS Sometimes it is desirable that when building
++## multiple versions of libgcc.a certain options should always be passed on
++## to the compiler.  In that case, set MULTILIB_EXTRA_OPTS to be the list
++## of options to be used for all builds.

++The following built-in functions are always available.  They
++all generate a Nios II Custom Instruction. The name of the 
++function represents the types that the function takes and 
++returns. The letter before the @code{n} is the return type
++or void if absent. The @code{n} represnts the first parameter
++to all the custom instructions, the custom instruction number.
++The two letters after the @code{n} represent the up to two 
++parameters to the function.
++
++The letters reprsent the following data types:
++@table @code
++@item <no letter>
++@code{void} for return type and no parameter for parameter types.
++
++@item i
++@code{int} for return type and parameter type
++
++@item f
++@code{float} for return type and parameter type
++
++@item p
++@code{void *} for return type and parameter type
++

+# Submitted:
+#
+# Dimitry Andric <dimitry@andric.com>, 2004-05-01
+#
+# Description:
+#
+# Nicholas Pitre released this patch for gcc soft-float support here: 
+# http://lists.arm.linux.org.uk/pipermail/linux-arm/2003-October/006436.html
+#
+# This version has been adapted to work with gcc 3.4.0.
+#
+# The original patch doesn't distinguish between softfpa and softvfp modes
+# in the way Nicholas Pitre probably meant.  His description is:
+#
+# "Default is to use APCS-32 mode with soft-vfp.  The old Linux default for
+# floats can be achieved with -mhard-float or with the configure
+# --with-float=hard option.  If -msoft-float or --with-float=soft is used then
+# software float support will be used just like the default but with the legacy
+# big endian word ordering for double float representation instead."
+#
+# Which means the following:
+#
+# * If you compile without -mhard-float or -msoft-float, you should get
+#   software floating point, using the VFP format.  The produced object file
+#   should have these flags in its header:
+#
+#     private flags = 600: [APCS-32] [VFP float format] [software FP]
+#
+# * If you compile with -mhard-float, you should get hardware floating point,
+#   which always uses the FPA format.  Object file header flags should be:
+#
+#     private flags = 0: [APCS-32] [FPA float format]
+#
+# * If you compile with -msoft-float, you should get software floating point,
+#   using the FPA format.  This is done for compatibility reasons with many
+#   existing distributions.  Object file header flags should be:
+#
+#     private flags = 200: [APCS-32] [FPA float format] [software FP]
+#
+# The original patch from Nicholas Pitre contained the following constructs:
+#
+#   #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
+#     %{mhard-float:-mfpu=fpa} \
+#     %{!mhard-float: %{msoft-float:-mfpu=softfpa;:-mfpu=softvfp}}"
+#
+# However, gcc doesn't accept this ";:" notation, used in the 3rd line.  This
+# is probably the reason Robert Schwebel modified it to:
+#
+#   #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
+#     %{mhard-float:-mfpu=fpa} \
+#     %{!mhard-float: %{msoft-float:-mfpu=softfpa -mfpu=softvfp}}"
+#
+# But this causes the following behaviour:
+#
+# * If you compile without -mhard-float or -msoft-float, the compiler generates
+#   software floating point instructions, but *nothing* is passed to the
+#   assembler, which results in an object file which has flags:
+#
+#     private flags = 0: [APCS-32] [FPA float format]
+#
+#   This is not correct!
+#
+# * If you compile with -mhard-float, the compiler generates hardware floating
+#   point instructions, and passes "-mfpu=fpa" to the assembler, which results
+#   in an object file which has the same flags as in the previous item, but now
+#   those *are* correct.
+#    
+# * If you compile with -msoft-float, the compiler generates software floating
+#   point instructions, and passes "-mfpu=softfpa -mfpu=softvfp" (in that
+#   order) to the assembler, which results in an object file with flags:
+#
+#   private flags = 600: [APCS-32] [VFP float format] [software FP]
+#
+#   This is not correct, because the last "-mfpu=" option on the assembler
+#   command line determines the actual FPU convention used (which should be FPA
+#   in this case).
+#
+# Therefore, I modified this patch to get the desired behaviour.  Every
+# instance of the notation:
+#
+#   %{msoft-float:-mfpu=softfpa -mfpu=softvfp}
+#
+# was changed to:
+#
+#   %{msoft-float:-mfpu=softfpa} %{!msoft-float:-mfpu=softvfp}
+#
+# I also did the following:
+# 
+# * Modified all TARGET_DEFAULT macros I could find to include ARM_FLAG_VFP, to
+#   be consistent with Nicholas' original patch.
+# * Removed any "msoft-float" or "mhard-float" from all MULTILIB_DEFAULTS
+#   macros I could find.  I think that if you compile without any options, you
+#   would like to get the defaults. :)
+# * Removed the extra -lfloat option from LIBGCC_SPEC, since it isn't needed
+#   anymore.  (The required functions are now in libgcc.)

+Status: submitted similar patch 2004-12-08
+
+This patch cleans up the initialization of thread_db.  It works for static
+binaries now.  The vsyscall patches hide this problem, since new static
+binaries will load the vsyscall DSO and then trigger thread_db; but
+this is still a good cleanup.

+Status: Unsuitable for upstream (at least, without a lot of arguing).
+
+GCC does not specify the state of every last register in the CIE.  Since
+GCC's focus is on correctness of runtime unwinding, any registers which
+have to be unwound will be specified; but unmodified registers will not
+be explicitly marked.  (How about modified, call-clobbered registers?
+I'm not sure if they are marked as unavailable.)
+
+GDB issues a noisy warning about this.  The warning is generally not useful,
+and we can get it extremely frequently (any time we load a new CIE).
+
+This patch disables the warning.  Alternately we could set the complaints
+threshold to zero, or implement a default frame init-register method for
+every architecture.  But someday the compiler will support using different
+calling conventions for internal functions, so that's not much of a stopgap. 
+ARM has a complex algorithm for handling this, involving scanning all CIEs -
+benefit not completely clear outside of the ARM context of flexible register
+sets.

+
+/* ============== original README ===================
+ *
+ * sstrip is a small utility that removes the contents at the end of an
+ * ELF file that are not part of the program's memory image.
+ * 
+ * Most ELF executables are built with both a program header table and a
+ * section header table. However, only the former is required in order
+ * for the OS to load, link and execute a program. sstrip attempts to
+ * extract the ELF header, the program header table, and its contents,
+ * leaving everything else in the bit bucket. It can only remove parts of
+ * the file that occur at the end, after the parts to be saved. However,
+ * this almost always includes the section header table, and occasionally
+ * a few random sections that are not used when running a program.
+ * 
+ * It should be noted that the GNU bfd library is (understandably)
+ * dependent on the section header table as an index to the file's
+ * contents. Thus, an executable file that has no section header table
+ * cannot be used with gdb, objdump, or any other program based upon the
+ * bfd library, at all. In fact, the program will not even recognize the
+ * file as a valid executable. (This limitation is noted in the source
+ * code comments for bfd, and is marked "FIXME", so this may change at
+ * some future date. However, I would imagine that it is a pretty
+ * low-priority item, as executables without a section header table are
+ * rare in the extreme.) This probably also explains why strip doesn't
+ * offer the option to do this.
+ * 
+ * Shared library files may also have their section header table removed.
+ * Such a library will still function; however, it will no longer be
+ * possible for a compiler to link a new program against it.
+ * 
+ * As an added bonus, sstrip also tries to removes trailing zero bytes
+ * from the end of the file. (This normally cannot be done with an
+ * executable that has a section header table.)
+ * 
+ * sstrip is a very simplistic program. It depends upon the common
+ * practice of putting the parts of the file that contribute to the
+ * memory image at the front, and the remaining material at the end. This
+ * permits it to discard the latter material without affecting file
+ * offsets and memory addresses in what remains. Of course, the ELF
+ * standard permits files to be organized in almost any order, so if a
+ * pathological linker decided to put its section headers at the top,
+ * sstrip would be useless on such executables.
