bmeurer	acd9c46ca7	[turbofan] Optimize certain chains of Branch into a Switch. This adds a new ControlFlowOptimizer that - for now - recognizes chains of Branches generated by the SwitchBuilder for a subset of javascript switches into Switch nodes. Those Switch nodes are then lowered to either table or lookup switches. Also rename Case to IfValue (and introduce IfDefault) for consistency.

svenpanne	d1b5aa0716	Removed most of the bogus CompilationInfo constructor calls. A CompilationInfo constructed from just an Isolate* and a Zone* is in weird an inconsistent state (calling e.g. flags() on it will crash), so we need to avoid them. This CL removes almost all of them, the remaining 2 call sites in (for testing only) will be handled in a separate CL. Things which have been changed: * Linkage is basically a decorator for CallDescriptor now. * ChangeLowering doesn't need Linkage at all. * JSGenericLowering doesn't need a full CompilationInfo, just a single flag. JSContextSpecializer doesn't need the full CompilationInfo, just a Context. * Removed unused CompilationInfo from SimplifiedLoweringTester. This nicely decouples things already a bit more, but there's still work to do...

michael_dawson	308d913a92	Contribution of PowerPC port (continuation of 422063005) - PPC dir update Contribution of PowerPC port (continuation of 422063005, 817143002 and 866843003) This patch brings the ppc directories up to date with our repo. We have removed 5 individual optimizations which require changes in both the ppc and common directories so they can be more easily reviewed on their own in subsequent patches. Subsequent patches will cover: - individual optimizations for PPC (5) - remaining AIX changes not resolved by 4.8 compiler (4.8 is only recently available for AIX) - incremental updates required to ppc directories due to platform specific changes made in google repos while we complete the above steps. With the update there are still some timeouts seen when run in simulated mode which may be a result of the missing optimizations. Once we have the optimizations in we will review the simulation results and address/exclude tests as necessary so that the simulated runs are clean. new file: src/compiler/ppc/code-generator-ppc.cc new file: src/compiler/ppc/instruction-codes-ppc.h new file: src/compiler/ppc/instruction-selector-ppc.cc new file: src/compiler/ppc/linkage-ppc.cc modified: src/ic/ppc/handler-compiler-ppc.cc modified: src/ic/ppc/ic-compiler-ppc.cc modified: src/ic/ppc/ic-ppc.cc modified: src/ic/ppc/stub-cache-ppc.cc modified: src/ppc/assembler-ppc.cc modified: src/ppc/assembler-ppc.h modified: src/ppc/builtins-ppc.cc modified: src/ppc/code-stubs-ppc.cc modified: src/ppc/code-stubs-ppc.h modified: src/ppc/codegen-ppc.cc modified: src/ppc/constants-ppc.h modified: src/ppc/deoptimizer-ppc.cc modified: src/ppc/disasm-ppc.cc modified: src/ppc/full-codegen-ppc.cc modified: src/ppc/interface-descriptors-ppc.cc modified: src/ppc/lithium-codegen-ppc.cc modified: src/ppc/lithium-codegen-ppc.h modified: src/ppc/lithium-ppc.cc modified: src/ppc/lithium-ppc.h modified: src/ppc/macro-assembler-ppc.cc modified: src/ppc/macro-assembler-ppc.h modified: src/ppc/regexp-macro-assembler-ppc.cc modified: src/ppc/regexp-macro-assembler-ppc.h modified: src/ppc/simulator-ppc.cc modified: src/ppc/simulator-ppc.h new file: test/unittests/compiler/ppc/instruction-selector-ppc-unittest.cc R=danno@chromium.org, svenpanne@chromium.org BUG= Review URL: https://codereview.chromium.org/901083004 Cr-Commit-Position: refs/heads/master@{#26471}	2015-02-05 19:02:07 +00:00

marja	c7851da4ae	Introduce LanguageMode, drop StrictMode. This enables adding more language modes in the future. For maximum flexibility, LanguageMode is a bitmask, so we're not restricted to use a sequence of language modes which are progressively stricter, but we can express the language mode as combination of features. For now, LanguageMode can only be "sloppy" or "strict", and there are STATIC_ASSERTS in places which need to change when more modes are added. LanguageMode is a bit like the old LanguageMode when "extended" mode was still around (see https://codereview.chromium.org/8417035 and https://codereview.chromium.org/181543002 ) except that it's transmitted through all the layers (there's no StrictModeFlag).

Benedikt Meurer	d8cfbc633d	[turbofan] Split pure nodes in the scheduler if beneficial. If a (pure) node has two or more uses, but there exists a path from the common dominator of these uses to end, which does not contain a use, then we split the node such that no unnecessary computation takes place.

bmeurer	59a02ebdbe	[turbofan] Ensure that NTLs are always properly connected to the end. Up until now we used a special Terminate node to artifically connect non terminating loops to the End node, but this was kind of adhoc and didn't work for the CFG. So without all kinds of weird hacks, the end block in the CFG will not be connected to NTLs, which makes it impossible to compute post dominance / control dependence in the current setting. So instead of Terminate, we add a special Branch to NTLs, whose condition is the special Always node, which corresponds to True, except that it cannot be folded away. This way we don't need any special machinery in the scheduler, since it's just a regular Branch.

jarin@chromium.org	bb5b39260b	Relax representation requirement in FrameStates. This change enables non-tagged representations in FrameStates. That allows us to run zlib with deoptimization support and have almost the same performance of the generated code (as the code with no deoptimization). Unfortunately, the frame states seem to confuse typer. As a consequence, we generate more representation changes, which in turn causes the scheduler to take a lot more time and memory (>4x). The added compiler time makes zlib with deopt be about 50% slower.

bmeurer@chromium.org	db33f07f79	[turbofan] Reenable value numbering.

bmeurer@chromium.org	8617b3acf8	[turbofan] Fix HashCode/Equals for floating point operators.

bmeurer@chromium.org	a17289f4bc	[turbofan] Drop broken StaticParameterTraits. The StaticParameterTraits are broken by design, and cause way too much trouble. The compilers usually pick the wrong specialization (i.e. the default specialization is picked for Load and Phi even tho there is a specialization for MachineType), which is not only the reason why GVN is ineffective and slow, but can also lead to correctness issues in some rare cases. Also clean up some minor bugs/inconsistencies on the way.
