fe3a6127c5 - Export JSSLOT_ITER_* from jsiter.cpp to jsiter.h, for jstracer.cpp to use. 
- Fix OBJ_GET_SLOT to be STOBJ_GET_SLOT in jsiter.cpp, no thread safety here (bug on file).
- Move JSNativeEnumerator from jsobj.cpp to jsobj.h for jstracer.cpp as well.
- Rename JOF_2BYTE JOF_UINT8 for consistency, and actually decompile it.
- Trace JSOP_FORVAR (can't do anything in JSOP_ITER, it comes before the loop).
- Shortened some guardMyLongSummerVacationWithinBounds names ;-).
- Removed/refactored to avoid dslots_ins obligation on all callers.

f1a5494d05 Major shakeup of the interning code for globals. Globals are now detected on demand as they are used and the slots are noted in treeInfo->globalSlots. At the same time the type is recorded in treeInfo->globalTypeMap. The stack type-map is maintained separately in treeInfo->stackTypeMap. All these structures are lists and are maintained as List<T> objects. Imports for globals can appear at the top (if we have already seen some imports for the loop header and are recompiling), or on the fly for lazily found values. We no longer intern all global properties that happen to match a name in the current function, and we also support inlining of functions that touch globals that are not used in the method where the trace started in. 2008-07-30 04:17:22 -07:00

8a7bb9c550 Smarter speculative demotion of numbers to integers and promotion of the trace seems to require actual doubles. If the number at entry looks like an int we make the slot an int and compile as such. If the loop-tail proves the slot to be a double, we recompile the trace. Currently such miss-speculation cannot be handled on secondary traces since we are currently unable to recompile the primary trace. Such secondary traces are blacklisted. 2008-07-27 02:15:17 -07:00
