|
* Implement down-recursion.Mike Pall2010-03-011-0/+3
|
* Correctly align and free allocated machine code areas.Mike Pall2010-02-271-1/+1
| | | | Bump default mcode area size to 64K for x64.
* Make penalty PRNG available for general use by compiler.Mike Pall2010-02-261-1/+9
|
* Move SIMD constants to jit_State to keep them in the low 4GB.Mike Pall2010-02-241-8/+20
|
* Randomize penalties for aborts and add blacklisting.Mike Pall2010-02-231-5/+8
|
* Don't eliminate SLOAD restores across RETF.Mike Pall2010-02-231-0/+1
| | | | Move restore-elimination logic into snapshot_slots().
* Back out history buffer for tailcall counts.Mike Pall2010-02-221-1/+1
| | | | Use an aggregate counter independent of frame depth.
* Add region selection for up-recursion and tail-recursion.Mike Pall2010-02-221-1/+1
|
* Eliminate redundant stack checks. Add checks for growing root traces.Mike Pall2010-02-211-1/+5
|
* Use a limited history buffer for tailcall counts while recording.Mike Pall2010-02-181-1/+1
|
* Drop obsolete shadow frame link stack.Mike Pall2010-02-181-1/+0
|
* Add shadow frame link stack for trace recorder.Mike Pall2010-02-041-1/+2
| | | | | Simplifies snapshots. Prerequisite for pre-call snapshots. Increases consistency for fast function calls, too.
* Clean up frame depth checks and loop detection.Mike Pall2010-02-031-0/+1
|
* Add frame and continuation flags to TRef and SnapEntry.Mike Pall2010-01-271-3/+8
|
* Compress snapshots using a simple, extensible 1D-compression.Mike Pall2010-01-261-3/+13
| | | | | | Typically reduces storage overhead for snapshot maps by 60%. The extensible format is a prerequisite for the next redesign steps: Eliminate IR_FRAME and implement return-to-lower-frame.
* Use dedicated type for snapshot map entry.Mike Pall2010-01-251-4/+6
| | | | Preparatory work for compressed snapshots.
* Bump all copyright dates to 2010.Mike Pall2010-01-091-1/+1
