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 :).

Refactoring: * consistent use of SmiTag/Untag * added a few Smi macros and helpers Improvements * small optimisations (e.g. merging untag and cmp #0) * added fixed point to double conversion instructions for simpler conversions More on the last point: a Smi can be seen as a fixed point number with the a one bit fractional part. Fixed to double instructions allow us to convert a Smi to a double without untagging.

First of all, it has nothing to do with Isolates, it is related to the assembler at hand. Furthermore, the saving/restoring is platform-independent. Cleaned up some platform-specific stuff on the way. Note that there are some things which still need some cleanup, like e.g. using EnumSet instead of uint64_t, making Probe() more uniform across platforms etc., but the CL is already big enough.

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).

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.

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".
