marja [Thu, 12 Feb 2015 13:02:30 +0000 (05:02 -0800)]
Parsing: Make Parser not know about Isolate during background parsing.

Parser must be able to operate independent of Isolate and the V8 heap during
parsing. After the heap-independent phase, there is a heap dependent phase,
during which we internalize strings, handle errors, etc.

This makes Isolate (also via CompilationInfo) unaccessible during parsing, and
thus decreases the probability of accidental code changes which would add
heap-dependent operations into the heap-independent phase.

Since Isolate is also accessible via CompilationInfo, now CompilationInfo is
only passed to the entry points of parsing, and not stored in Parser.

Copy the corresponding opt_count_and_bailout_reason info when invoking Runtime_SetCode.

  This error is exposed by this CL:  https://codereview.chromium.org/817293005.

   This CL set all Buildin JS function to optimization_disabled.
   And set the bailout reason to "kBuiltinFunctionCannotBeOptimized". But in Runtime_SetCode() function.
   It copied the the compiler_hints which include the "bool optimization_disabled" value,
   But the corresponding Bailout reason is not copied.
   This leads to the check error in "CompilationInfo::AbortOptimization(...)" function.

  This issue is exposed on turbofan unsupported X87 platform. Crankshaft is invoked to compile
 the typed array function Uint8Array.

X87:  Parsing: Make Scope not know about Isolate.

port 5d68529be240a1fc9fcc67c8950ead4baf7604e4 (r26546)

original commit message:

   Parsing: Make Scope not know about Isolate.

  Scope, like Parser, must be able to operate independent of Isolate and the V8
  heap (for background parsing). After the heap-independent phase, there is a heap
  dependent phase, during which we do operations such as scope anaylysis.

  This CL makes the phases explicit by not telling Scope about the Isolate too
  early (during the heap-independent phase, Scope should know nothing about
  Isolate). This decreases the probability of accidental code changes which would
  add heap-dependent operations into the heap-independent phase.

  2) c_entry_fp assignment call was added to EntryGenerator::Generate

A CompilationInfo constructed from just an Isolate* and a Zone* is in
weird an inconsistent state (calling e.g. flags() on it will crash),

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.

MIPS64: Propagate DeoptInfo to cpu-profiler

Port 86cae1633caa31f2225b6932850fb13d3a21cf59

Original commit message:
1) Deoptimizer::Reason was replaced with Deoptimizer::DeoptInfo
because it also has raw position. Also the old name clashes with DeoptReason enum.

2) c_entry_fp assignment call was added to EntryGenerator::Generate
So we can calculate sp and have a chance to record the stack for the deopting function.
btw it makes the test stable.

3) new kind of CodeEvents was added to cpu-profiler

4) GetDeoptInfo method was extracted from PrintDeoptLocation.
So it could be reused in cpu profiler.

MIPS: Parsing: Make Scope not know about Isolate.

Port 5d68529be240a1fc9fcc67c8950ead4baf7604e4

Original commit message:
Scope, like Parser, must be able to operate independent of Isolate and the V8
heap (for background parsing). After the heap-independent phase, there is a heap
dependent phase, during which we do operations such as scope anaylysis.

This CL makes the phases explicit by not telling Scope about the Isolate too
early (during the heap-independent phase, Scope should know nothing about
Isolate). This decreases the probability of accidental code changes which would
add heap-dependent operations into the heap-independent phase.
