|\ \ | | | | | | new bytecode emitter, GenBCode (11th attempt)
| * | new bytecode emitter, GenBCode, for now under a flagMiguel Garcia2013-06-012-0/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GenBCode is a drop-in replacement for GenASM with several advantages: - faster: ICode isn't necessary anymore. Instead, the ASTs delivered by CleanUp (an expression language) are translated directly into a stack-language (ASM Tree nodes) - future-proofing for Java 8 (MethodHandles, invokedynamic). - documentation included, shared mutable state kept to a minimum, all contributing to making GenBCode more maintainable than its counterpart (its counterpart being GenICode + GenASM). A few tests are modified in this commit, for reasons given below. (1) files/neg/case-collision Just like GenASM, GenBCode also detects output classfiles differing only in case. However the error message differs from that of GenASM (collisions may be show in different order). Thus the original test now has a flags file containing -neo:GenASM and a new test (files/neg/case-collision2) has been added for GenBCode. The .check files in each case show expected output. (2) files/pos/t5031_3 Currently the test above doesn't work with GenBCode (try with -neo:GenBCode in the flags file) The root cause lies in the fix to https://issues.scala-lang.org/browse/SI-5031 which weakened an assertion in GenASM (GenBCode keeps the original assertion). Actually that ticket mentions the fix is a "workaround" (3) files/run/t7008-scala-defined This test also passes only under GenASM and not GenBCode, thus the flags file. GenASM turns a bling eye to: An AbstractTypeSymbol (SI-7122) has reached the bytecode emitter, for which no JVM-level internal name can be found: ScalaClassWithCheckedExceptions_1.E1 The error message above (shown by GenBCode) highlights there's no ScalaClassWithCheckedExceptions_1.E1 class, thus shouldn't show up in the emitted bytecode (GenASM emits bytecode that mentions the inexistent class).

Partially reverting just this change restores the correct behaviour: ``` - if (sym.isStable && pre.isStable && !isByNameParamType(tree.tpe) && + if (treeInfo.admitsTypeSelection(tree) && ``` This patch embeds the check for by-name parameter types into `TreeInfo.isStableIdentifier`. That code already checks for `Symbol#isStable`, which exludes direct references to by-name parameters. But the additional check is required to deal with by-name parameters in function types, e.g `(=> Int) => Any`. Open question: should we go further and embed this check in `isStable`? Currently: final def isStable = isTerm && !isMutable && !(hasFlag(BYNAMEPARAM)) && (!isMethod || hasStableFlag) Such function types are an underspecified corner of the language, albeit one that is pretty useful writing, for example, in the signature of a lazy foldRight that can operate over infinite structures: def foldRight[A, B](fa: F[A], z: => B)(f: (A, => B) => B): B The next commit subjects them to a little testing.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there's no Predef.$scope but xml is being used, the compiler aliases scala.xml.TopScope to $scope. There must be a scala.xml package when xml literals were parsed. For compatibility with the old library, which relied on $scope being in scope, synthesize a `import scala.xml.{TopScope => $scope}` when xml is needed, but there's no Predef.$scope and the old library is detected (scala.xml.TopScope exists).

In that case, the spurious warnings came because we warned in the typechecker, which was also called in erasure. In this case, we are issuing the warning in Uncurry, so we must be mindful of the pattern matchers translations of non-trivial catch patterns, which look like: case (ex8 @ _) => { <synthetic> val x5: Throwable = ex8; case11(){ if ({ case14(){ if (x5.$isInstanceOf[NullPointerException]()) matchEnd13(true) else case15() }; case15(){ if (x5.$isInstanceOf[RuntimeException]()) matchEnd13(true) else case16() }; case16(){ matchEnd13(false) }; matchEnd13(x: Boolean){ x } }) This commit detects that `ex8` is synthetic and disables the warning.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Scala type information is stored in classfiles in encoded in a String in the ScalaSignature annotation. When it is too big for a single String, it is split into an array of Strings in a different annotation, ScalaLongSignature. The enclosed test, with a class containing 3000 methods, uses the latter. It exposes a bug in the way runtime reflection decodes that data. It must concatentate and *then* decode, rather that the other way around.

This led to NPEs for really weird macro defs that refer to local methods as their corresponding macro impls. Now I check for this corner case, and the stuff now longer crashes. This was wrong; this is how I fixed it; the world is now a better place.

Part of this happens in `Typer#stabilize`. This was trying to determine if an Ident or Select node was a call to `getClass` by merits of the name of the tree's symbol and by checking that the its type (if it was a MethodType or PolyType) had no parameters in the primary parameter list. Overloaded user defined `getClass` methods confused this check. In the enclosed test case, the tree `definitions.this.getClass` had an `OverloadedType`, and such types always report an empty list of `params`. This commit: - changes `stabilize` to use `isGetClass`, rather than the homebrew check - changes `isGetClass` to consider a `Set[Symbol]` containing all `getClass` variants. This moves some similar code from `Erasure` to `Definitions` - keeps a fast negative path in `isGetClass` based on the symbol's name

However unlike fields, methods and constructors, inner classes don't need to be entered explicitly - they are entered implicitly when being loaded. This patch fixes the double-enter problem, make sure that enter-on-load uses the correct owner, and also hardens jclassAsScala against double enters that can occur in a different scenario.

Unfortunately, sometimes private methods might be compiled down to public Java methods, so stripping them off might lead to binary incompatibilities. This particular commit recovers from this problem caused by https://github.com/scala/scala/commit/5e715396af.

It turns out this approach was breaking the working variations in the submitted test case even as it was unbreaking the unworking one, but I never managed to uncomment them. Fortunately retronym's test case was not so lackadaisical.

This leads to tighter cohesion and better code reuse as the cake is isolated from the rest of the compiler and is much easier to evolve than just a method body. Increased convenience of coding macro compilation allowed me to further clarify the implementation of the macro engine (e.g. take a look at Validators.scala) and to easily implement additional features, namely: 1) Parameters and return type of macro implementations can now be plain c.Tree's instead of previously mandatory c.Expr's. This makes macros more lightweight as there are a lot of situations when one doesn't need to splice macro params (the only motivation to use exprs over trees). Also as we're on the verge of having quasiquotes in trunk, there soon will be no reason to use exprs at all, since quasiquotes can splice everything. 2) Macro implementations can now be defined in bundles, standalone cakes built around a macro context: http://docs.scala-lang.org/overviews/macros/bundles.html. This further reduces boilerplate by simplifying implementations complex macros due to the fact that macro programmers no longer need to play path-dependent games to use helpers.
