a3eb60b77e Add limited outerlining. Much of this will be subsumed by nested trees. 2008-07-27 14:28:56 -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
Andreas Gal
a4fc19765e Don't try to demote slots on secondary traces (we have to recompile the primary trace as well for that, which we currently don't do.) 2008-07-25 19:30:33 -07:00

059abfa50f Added sunspider tests to t/ for dvander. 2008-07-25 18:43:19 -07:00

812989bb8a Eliminate EntryRegs. Its not safe to keep a reference to the entry SP since we might extend the tree from a different outer stack frame. Instead just store the entryStackDepth. 2008-07-25 18:22:15 -07:00
Andreas Gal
bbb1bc89c0 Print real recording point, not entryRegs and add an assert that makes sure the guard we come out of is associated with the tree we entered into. 2008-07-25 18:13:57 -07:00

1b7930d39d The VP engineering broke JSOP_NAME! We have to check whether the slot is actually interned and otherwise abort. 2008-07-25 16:51:42 -07:00

d952f192ba Can't use lr->from. Seems to not get set in certain cases. Go figure. The nanojit tree code is really weird. 2008-07-25 02:29:36 -07:00

6df91a21a0 Make the interpreter notify us when frames are popped so we see he right cx->fp value. Fix return value tracking for JSOP_STOP. 2008-07-24 10:35:10 -07:00
Andreas Gal
5ae4ef819e Backed out changeset a58e7ce6eb7f. stack(0) is wrong, if at all it should have been stack(-(1 + argc)). But anyway, its impossible to write through to the frame via set() at that point because leaveFrame() doesn't actually modify cx->fp. We need to wait for the interpreter to do so. Until then nativeFrameOffset produces incorrect values and the assert fails in set. 2008-07-24 10:09:51 -07:00

41e0593392 Maintain a separate frame for globals using InterpState->gp.
This will allow nested loops to access the globals interned by outer loops while at the same time sharing parts of the stack of the outer loop.

117bc4d9f9 Add a fast path for nativeFrameOffset that walks entire groups at a time, not slots. Check against the result calculated by the FORALL macro in DEBUG builds (for sanity). 2008-07-23 16:39:17 -07:00

df280d08d7 When addressing locations above the stack water level, use ->sp as base. Shaver accidently changed this to ->spbase when merging Igor's patch, so we were writing past the water mark and the stores were killed. 2008-07-23 15:48:15 -07:00

5dd9876515 Lazy fill the stackTracker as we lookup the nativeFrameOffset for values. Purge all entries related to the current frame when it is popped. This code could be further simplified if Tracker was a template. 2008-07-23 02:57:56 -07:00
