* Avoid reuse of PHI registers, even for duplicate right PHIs.Mike Pall2010-01-271-1/+1
|
* Eliminate IR_FRAME. Replace with KGC and TRef/SnapEntry flags.Mike Pall2010-01-271-39/+28
|
* Add frame and continuation flags to TRef and SnapEntry.Mike Pall2010-01-271-17/+17
|
* Compress snapshots using a simple, extensible 1D-compression.Mike Pall2010-01-261-53/+48
| | | | | | 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.
* Add missing eviction in asm_obar().Mike Pall2010-01-261-0/+1
|
* Fill gaps in frames (caused by metamethod calls) with nil.Mike Pall2010-01-261-2/+2
| | | | Simplifies storing snapshots to stack.
* Use dedicated type for snapshot map entry.Mike Pall2010-01-251-5/+5
| | | | Preparatory work for compressed snapshots.
* Decouple guard vs. INT check vs. TYPECHECK semantics for SLOAD.Mike Pall2010-01-191-2/+4
|
* Fix broken intarith + testop optimization.Mike Pall2010-01-191-1/+1

* Improve alias analysis of upvalues using a disambiguation hash value.Mike Pall2010-01-091-3/+3
| | | | | | | | All upvalue objects hold a disambiguation hash value now. It's built from the parent prototype and the slot number. Different hash values imply the upvalues cannot alias. Same hash values don't imply anything (collision or different closures). Upvalue disambiguation makes use of a reduced hash due to IR contraints.
* Fix 32/64 bit portability issue with upval->v.Mike Pall2010-01-091-1/+1
|
* Bump all copyright dates to 2010.Mike Pall2010-01-091-1/+1
|
* Add SSE variant of pow/powi to interpreter.Mike Pall2009-12-251-39/+72
| | | | | | Use SSE pow/powi helper functions from compiled code. Cleanup use of helper functions. Related cleanups of folding functions in x64 interpreter.
* Use SSE variants for IRFPM_FLOOR/CEIL/TRUNC unless SSE4.1 available.Mike Pall2009-12-221-0/+18
|
* Fast forward to sync public repo.Mike Pall2009-12-081-251/+347
| | | | | | | | Compile math.sinh(), math.cosh(), math.tanh() and math.random(). Compile various io.*() functions. Drive the GC forward on string allocations in the parser. Improve KNUM fuse vs. load heuristics. Add abstract C call handling to IR.
