I'm planning to use it in DevTools heap profiler. It is a common scenario in debugging memory leaks to enforce GC, then perform an operation, then enforce GC again to check for non-collected (that is, leaked) objects. Using the existing GC extension isn't possible because it doesn't exposed in the normal operation mode of Chromium.

Optimization was only unsafe if new-space was in the low half of memory and an object could be located in the top half at an addressed that only differ from a new-space address by the high bit.

- Restructured the entire function because: During the simple style fix I discovered that this whole routine was hard to read due to a general lack of comments. While adding comments I realized that the function was also skipping entries if there were two consecutive entries in the maps file.

generated in one-pass from the source AST, code is generated from the CFG. Enabled by the flag --multipass and disabled by default. Rudimentary and currently only supports literal expressions and return statements. There are some other known limitations (e.g., missing support for tracing).

AstNode in case we ever want to have some other kind of node.

Allocate the code stubs dictionary and non monomorphic cache dictionary with an initial size which avoids these dictionaries to be expanded during bootstrapping. This gets rid of 9 dictionary expansions during bootstrapping. Preallocate the dictionary when normalizing an object to a size sufficient for holding the number of properties which is expected to be added to the object. This is used when ceating an object from an object literal boilerplate where multiple properties are known to be added. This gets rid of 10 dictionary expansions during bootstrapping. There are now 3 dictionary expansions left during bootstrapping.

Changed CalledAsConstructor to process the raw runtime stack directly, rather than using a StackFrameIterator. Using an interator turns out to be quite expensive and the vast majority of the work done is not relevant to deciding if we've been called as a constructor. This speeds up getElementById by ~13%.

As we'll have several aspects of heap profiling, it is more handy to control them using binary flags than by individual functions. CPU profiling represent just a particular aspect to control, so {Pause,Resume}Profiler and IsProfilerPaused are only left for compatibility. For now, PROFILER_FLAG_HEAP_STATS and PROFILER_FLAG_JS_CONSTRUCTOR are equivalent, but later will be split.

It is activated with '--log-gc' flag. JS object size is calculated as its size + size of 'properties' and 'elements' arrays, if they are non-empty. This doesn't take maps, strings, heap numbers, and other shared objects into account. As Soeren suggested, I've moved ZoneSplayTree from jsregexp to zone, and removed now empty jsregexp-inl header file.
