Slava Pestov bb202805d8 compiler.cfg: don't generate useless methods in instruction meta-programming. reduces bootstrap time 2009-11-02 20:11:29 -06:00
Slava Pestov 775b9af2f7 compiler: eliminate boilerplate by centralizing info in declarative INSN: syntax 2009-09-02 06:22:37 -05:00
Slava Pestov b35a01879e %box-displaced-alien: fix clobberage found by Doug 2009-08-30 05:11:08 -05:00
Slava Pestov 9caf3f9248 compiler: new inline intrinsic for <displaced-alien> where the inputs have known types; value numbering now eliminates unnecessary allocation of displaced aliens if the result is immediately unboxed again 2009-08-27 00:06:19 -05:00
Slava Pestov 2d575d7ec9 compiler.cfg: virtual registers are integers now, and representations are stored off to the side. Fix bug in representation selection that would manifest if a value was used as a float and a fixnum in different branches; cannot globally unbox float in this case 2009-08-08 04:02:18 -05:00
Slava Pestov 4d2160799f Split off the notion of a register representation from a register class 2009-08-07 17:44:50 -05:00
Slava Pestov 68d06c4b06 compiler.cfg.linear-scan.assignment: modifies instructions in place instead of storing a registers assoc for further compile-time performance improvement 2009-07-29 06:36:14 -05:00
Slava Pestov a2ae560a8a compiler.cfg.ssa.construction: use the optimization from the pruned-SSA paper to minimize stack pushing and popping 2009-07-28 11:52:42 -05:00
Slava Pestov 127de28195 compiler.cfg.copy-prop: Global copy propagation 2009-07-24 05:30:46 -05:00
Slava Pestov 5d9f7b0ed2 compiler.cfg: Major restructuring -- do not compute liveness before local optimization, and instead change local optimizations to be more permissive of undefined values. Now, liveness is only computed once, after phi elimination and before register allocation. This means liveness analysis does not need to take phi nodes into account and can now use the new compiler.cfg.dataflow-analysis framework 2009-07-22 03:08:28 -05:00
Slava Pestov 9b3c593332 compiler.cfg.ssa: Cytron's SSA construction algorithm 2009-07-21 17:49:30 -05:00
Slava Pestov 99faf3c79f Overflowing fixnum intrinsics now expand into several CFG nodes. This speeds up the common case since only the uncommon case is now a stack syncpoint 2009-07-16 18:29:40 -05:00
Slava Pestov 01f9addc3a compiler.cfg.branch-splitting: split blocks with successors 2009-07-13 10:44:08 -05:00
Slava Pestov fe32e13fb0 compiler.cfg.value-numbering: factor out value renaming into a separate compiler.cfg.renaming vocabulary 2009-07-09 23:14:26 -05:00
