Björn Lindqvist 163fef12f9 compiler.cfg.*: detached the normalize-height and schedule-instructions passes
those stages cause uninitialized "holes" in the stacks which in turn
causes gc errors if stack underflows occur

John Benediktsson 068ddd6c7b compiler: cleanup cfg passes to have stack effect ( cfg -- ) 2014-12-11 12:48:43 -08:00
Björn Lindqvist c85175c10c compiler.cfg.*: new utility word apply-passes to improve the looks of long cleave's where each quotation only contains one word 2014-12-11 14:30:47 +01:00
Björn Lindqvist 8744d908b6 compiler.cfg.*: fix stack effect of compiler passes in optimize-cfg
since they all modify the cfg in place, it is better if their stack
effect is ( cfg -- ) instead of ( cfg -- cfg' )

Slava Pestov 1e841e5086 compiler.cfg.ssa.destruction: more aggressive coalescing work in progress 2009-09-27 17:17:26 -05:00
Slava Pestov daff63071f Fix the build 2009-09-09 13:44:54 -05:00
Slava Pestov 7e2f0e5dbf compiler: separate ##save-context instruction from ##alien-invoke, generate a ##save-context for libm calls, and add a pass to combine multiple context saves within a basic block. Fixes crashes with FP traps thrown by libm functions on x86-32 2009-09-08 21:50:55 -05:00
Doug Coleman 3f3d57032b Delete empty unit tests files, remove 1- and 1+, reorder IN: lines in a lot of places, minor refactoring 2009-08-13 19:21:44 -05:00
Slava Pestov d0c393aa60 compiler.cfg: new system to track when results of analyses need to be recomputed (reverse post order, linear order, predecessors, dominance, loops). Passes can now call needs-predecessors, needs-dominance, needs-loops at the beginning, and cfg-changed, predecessors-changd at the end. Linearization order now takes loop nesting into account, and linear scan now uses linearization order instead of RPO. 2009-08-08 20:02:56 -05:00
Slava Pestov e21ca289c3 compiler.cfg.representations: new pass to make global unboxing decisions, relies on new compiler.cfg.loop-detection pass for loop nesting information 2009-08-08 00:24:46 -05:00
Slava Pestov 725280d424 Split off the notion of a register representation from a register class 2009-08-07 17:44:50 -05:00
Slava Pestov 370f4c081d compiler.cfg: convert code into two-operand form before SSA destruction; SSA destruction now operates on a relaxed SSA form where multiple defs of the same vreg are allowed, but only within a single basic block. This makes linear scan's coalescing redundant, allowing it to be removed completely 2009-08-05 18:57:46 -05:00

Slava Pestov 44bcd258f6 Insert _loop-entry in linearization pass instead of in CFG builder, so that optimizations don't have to worry about it 2009-07-22 06:05:17 -05:00
Slava Pestov 25c42d04fd compiler.cfg: Fix conflicts after merging local optimization refactoring into DCN branch 2009-07-22 03:17:53 -05:00
Slava Pestov 21a012e3d7 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
