47ae25da20 Make entryFrame/entryRegs relative to the tree entry since we only adjust ip/sp/rp when exiting from the tree, not in between fragments. 2008-07-18 16:21:22 -07:00

9f761173f0 Added a callstack that will track the pc of the call that caused a function call to be inlined. This is necessary to recover from deep side exits inside inline functions. The callstack is subject to store elimination, so unnecessary stores to the stack will go dead automatically during compilation (i.e. if we inline a function that doesn't have side exits.) 2008-07-14 19:12:50 -07:00

b5e654f120 5 hours of debugging, and 9 keystrokes to fix it. That was one expensive bug. shaver's reduced fannkuch example works now. I think independently of this one we don't check properly for index underflow in dense arrays. Shaver is going to have to take a look at that (this fix makes fannkuch indexes not become negative, but doesn't explain why we crash so hard if they do become negative). 2008-07-12 00:27:21 -07:00

b222836a73 Don't demote u2f conversions and sink the type cast into the side exit type map, because this loses the sign bit for unsigned values. We could fix this by adding an explicit unsigned type to the map, but for now I think we should stick to int/double only since there is the risk of fanning out trees. Crypto doesn't seem to use ush all that much so we should be ok performance-wise. 2008-07-11 13:18:29 -07:00

20a5a9ef31 1. Fix inc to address the right result stack slot; 2. Require via assertions that the interpreter memoize implicit gvars (patch to do that next; bitwise-and will assert until that lands). 2008-07-09 15:15:32 -07:00

202ec610da Removed assert that compares nativeFrameSlots to nativeFrameOffset since nativeFrameOffset is undefined in case sp is at sp+depth, so the assert sometimes randomly bites. Also fixed typo in cmp(). trace-test.js compiles now. 2008-07-09 10:05:59 -07:00

19a2dcb6f5 Fixed bug in nativeFrameSlots and use an assert to compare the result with nativeFrameOffset (which is slower, but more precise). 2008-07-09 00:26:01 -07:00

1c24e264ad Removed numMapEntries since typeMap is not really part of the SideExit struct yet anyway. 2008-07-09 00:13:35 -07:00

216f33a0bb sp_adj is now maintained in bytes, not words, so +8 is now the magic value to point to the top of the stack. All stores above that watermark are eliminated by StackFilter in nanojit. 2008-07-08 21:03:30 -07:00
