I'd like to propagate bailout reason to cpu profiler. So I need to save it into heap object SharedFunctionInfo. But: 1) all bailout reason strings spread across all the sources. 2) they are native strings and if I convert them into String then I may have a performance issue. 3) one byte is enough for 184 bailout reasons. Otherwise we need 8 bytes for the pointer. Also I think it would be nice to have error strings collected in one place. In that case we will get additional benefits: It allows us to keep this set of messages under control. It gives us a chance to internationalize them. It slightly reduces the binary footprint. From the other hand the developers have to add new strings into that enum.

This is just a rename change with the exception of a bug found along the way in CodeStubGraphBuilder<FastCloneShallowArrayStub>::BuildCodeStub(). There, the intent is to get the boilerplate object from an AllocationSite. But the wrong HObjectAccess was used. It only succeeds because it happened to be the same offset :).

in preparation of the introduction of ES6 'symbols' (aka private/unique names). The SymbolTable became the StringTable. I also made sure to adapt all comments. The only remaining use of the term "symbol" (other than unrelated uses in the parser and such) is now 'NewSymbol' in the API and the 'V8.KeyedLoadGenericSymbol' counter, changing which might break embedders. The one functional change in this CL is that I removed the former 'empty_string' constant, since it is redundant given the 'empty_symbol' constant that we also had (and both were used inconsistently).

This includes: * Adding support for saving callee-clobbered double registers in Crankshaft code. * Adding a new "HTrapAllocationMemento" hydrogen instruction to handle AllocationSiteInfo data in crankshafted stubs. * Adding a new "HAllocate" hydrogen instruction that can allocate raw memory from the GC in crankshafted code. * Support for manipulation of the hole in HChange instructions for Crankshafted stubs. * Utility routines to manually build loops and if statements containing hydrogen code.

we store an AllocationSiteInfo object right after the JSArray, with a pointer to the boilerplate object. Later, if the array transitions we check for the continued existence of the temporary AllocationSiteInfo object (has no roots). If found, we'll use it to transition the boilerplate array as well.

There are now NONE and NONE64 RelocInfo types, but only ARM uses them both at the same time. They were added in: https://chromiumcodereview.appspot.com/11191029/ I'll rename NONE to NONE32 in a later CL. This CL cleans up the RelocInfo::NONE usage by: - Using RelocInfo::IsNone when testing for NONE-ness. - Using NONE on 32-bit platforms (MIPS and IA32), and NONE64 on 64-bit platforms (x64). This cleans up the code and prevents it from evolving bugs in the future because NONE32 and NONE64 are used in misleading ways.

Making the code size predictable is hard, and to make things even more complicated, the start of a function can contain various stuff like calls to a profiling hook, receiver adjustment or dynamic frame alignment. Instead of tackling all these problems separately, we now simply record the offset where patching should happen later in the Code object itself.

When code objects in the heap for FUNCTIONs and OPTIMIZED_FUNCTIONs are marked by the GC, their prologue is patched with a call to a stub that removes the patch. This allows the collector to quickly identify code objects that haven't been executed since the last full collection (they are the ones that sill contain the patch). The functionality is currently disabled, but can be activated by specifying the "--age-code".

1. The write barrier (RecordWriteStub) expects that pointer stored points to an initialized object. Specifically, the map must be set before it is stored. 2. The backing store for smi-only elements can only be reused for double elements if it is in new-space. Otherwise, we need to allocate a fresh one because the old one is in pointer-space and the new one has to be in data-space.
