* ctrl-C will no longer kill the repl unless you hit it again
* ctrl-Z will no longer make the repl useless because of jline
In the service of the first I wrote signal handling code, which we can
put to use in other ways as well. No review.

I avoided creating any dependency on yourkit. In addition, there was
no way to give arguments to the JVM without losing the ones defined in
ANT_OPTS, which has been a massive pain for a while. So there is now
"jvm.opts" which is simply appended to ANT_OPTS, e.g.
% ant -Djvm.opts=-verbose
[echo] Forking with JVM opts: -Xms1536M -Xmx2g -Xss1M -XX:MaxPermSize=192M -XX:+UseParallelGC -verbose
There is a minimal stub defining a profiler interface:
scala.tools.util.Profiling
Then the yourkit wrapper implements that interface. Once your locker has
been rebuilt once, you can do this:
ant yourkit.run
And it will build quick.lib/comp with profiling enabled, assuming it
can find the necessary files. See the yourkit.init target for values to
change: or ant -Dyourkit.home=/path/to/it might be enough.

been ignoring their painstakingly set classpaths and using whatever they
can find in the vicinity of the scala script, which works OK for pack
but not so well for quick.
I also added a build.xml feature so you can drop jars into a dir
and have them automatically used everywhere. The directory is
lib/extra. Pro tip: add lib/extra to .gitignore and put jars like
yjp-controller-api-redist.jar in there.
Closes #3706, no review.

Another exciting development in the world of -Y options which I and
three other people will use. Today's is -Yrich-exceptions. Use it like
so:
SOURCEPATH=/path/to/src scalac -Yrich-exceptions a.scala
In the repl, -Yrich-exceptions will cause lastException to be bound to
an Exceptional instead of old rusty Throwable. That spins up new powers:
scala> Nil.head
[Nil.head] (List.scala:389)
(access lastException for the full trace)
scala> lastException.show
/* The repl internal portion of the stack trace is elided. */
[Nil.head]
386: override def isEmpty = true
387: override def head: Nothing =
388: throw new NoSuchElementException("head of empty list")
*389: override def tail: List[Nothing] =
390: throw new UnsupportedOperationException("tail of empty list")
391: // Removal of equals method here might lead to an infinite recursion similar to IntMap.equals.
392: override def equals(that: Any) = that match {
[line0.<init>] (<console>:6)
[line0.<clinit>] (<console>:-1)
Also try "lastException.showTable" but this is getting a little long for
more excerpt. No review.

Half of an implementation of sealedness for java enums. Since it's only
half it's behind -Xexperimental, but it works like a charm for the half
where it works (that being compiling against bytecode.) Need input on
how to approach the source half. References ticket #2442. Review by
moors.

Some more work on options related to showing compiler structures during
compilation. The pickler knew more than was healthy about things like
compiler settings, so I let the pickler worry about pickling and moved
that logic somewhere closer to the surface. Some convenience oriented
tweaks to command line phase parsing. The end result is as follows (some
output trimmed for brevity.)
// dippy.scala
class Dippy {
def f[T <: Dippy](x: T) = (x, x)
object DingusDippy extends util.Random { }
}
// className@phaseString should be reliably unambiguous
% scalac -Xshow-class Dippy@typer,erasure,jvm dippy.scala
<<-- class Dippy after phase 'typer' -->>

final object DingusDippy extends object Dippy.this.DingusDippy
def f[T <: Dippy](x: T): (T, T)

While investigating the cause of #3984, discovered that set hashcodes
were being calculated like:
elems map (_.hashCode) sum
This looks totally correct, except that because of set+map semantics it
drops all the duplicate hashcodes and therefore calculates the wrong
sum anytime there are unequal elements with equal hashcodes. If we're
married to the set+map semantics (and I don't know what could be done
about it) I had better get a proper -Xlint going because this is one of
those traps which shoots bees out of its mouth. No review.

distribution can now be built with that option, with or without
optimization, and almost all tests cases can. (Those which can't are due
to different -Ycheck: issues.)
Major changes of interest are as follows:
* LOAD_EXCEPTION and THROW are parameterized on the throwable symbol.
* Does not squash all traits down to AnyRef, but instead deals with
issues as they arise. By observation the cases where one needs a "Foo
with Product" to manifest as both a "Foo" and a "Product" at different
places are quite rare, so we need not throw out the whole baby. *
Exception handlers now have positions. * The remaining checker failures
removed, such as CALL_METHOD wanting to pop a value off the stack
after calling a constructor. * Many multiply defined values such as
REFERENCE(ObjectClass) put in one place (ICodes.scala) and reused. *
-Ycheck:icode output (if also given -Ydebug) worthy of Michelangelo.
Here is a class and the -Ycheck:icode -Ydebug output for f's block.

def f(x: Int, y: String) =
try println(x + y.length)

Modified the lub calculation in TypeKinds to avoid the icode checker
failures described in ticket #3872. This does not alter the compiler's
lub calculation as I'd hoped because I could not figure out how to
accomplish this without having unintended consequences. I think that
either Symbol.isLess could be adjusted, or perhaps the implementation of
spanningTypes, or other places... but it eluded me and I defer to the
type wizards. No review.

A bit of -Xshow-class / -Xshow-object which didn't quite make the Global
patch. Now type selections should do the right thing, e.g.
scalac -Xshow-class Global#Run
src/compiler/scala/tools/nsc/Global.scala

even more thrills. No review.
