Björn Lindqvist 837e098d41 compiler.cfg.*: a little more docs 2015-04-29 09:31:54 -07:00
Björn Lindqvist ba4736ff75 compiler.cfg.stacks.local: change current-height to a two-tuple { { d emit-d } { r emit-r } } it makes the code a bit simpler 2015-04-29 09:31:54 -07:00
Björn Lindqvist c360f0123b compiler.cfg.stacks: a few unused words removed 2015-04-29 09:31:54 -07:00
Björn Lindqvist acc1bd3221 compiler.*: removing the check-d and check-r slots from gc-map and adjusting code that depended on those 2015-04-29 09:31:53 -07:00
Björn Lindqvist 2cd2aa498a VM: the compiler doesn't emit any live overinitialized locations anymore
Any overinitialized location immediately becomes garbage and is not
reused again. This is very nice because then the gc maps can be
simpler again.

Björn Lindqvist ded3760d46 compiler.*: merge of ##inc-r and ##inc-d into one instruction ##inc with a loc slot
this is nice because it leads to simpler code and matches how ##peek and ##replace instructions work

Björn Lindqvist 640759ffed compiler.cfg.*: new step in finalization: clear-uninitialized
this step is supposed to analyze the cfg, find where there are peeks
that can cause stack underflow, and insert replace-imm instructions so
that there are no uninitialized stack locations if they do. could fix #1187

Björn Lindqvist ffacc8370d compiler.cfg.stacks.vacant: ##call instructions clear the set of overinitialized locations 2014-09-08 14:54:18 -07:00
Björn Lindqvist 9836d6a1d0 VM: move the stack scrubbing logic to call_frame_slot_visitor to avoid visiting the callstack twice
primitive_minor_gc() iterates the stack twice, first to scrub stack
locations, then to trace overinitialized ones and gc roots. By running
visit_callstack() before visit_stack_elements() you only need to do it
once.

Björn Lindqvist 46082d836a compiler.cfg.stacks.vacant: invert meaning of 0/1 for overinit:ed locs to make some logic simpler 2014-09-08 14:54:17 -07:00
Björn Lindqvist 70e4f2a8b7 compiler.cfg.instructions: added check-d and check-r slots to gc-map
the data is output from compiler.cfg.stacks.vacant in a reasonable
format but not yet used for code generation.

Björn Lindqvist e961a03837 compiler.cfg.stacks.vacant: compiler pass replacing uninitialized for more accurate stack maps
This pass uses a better algorithm for keeping track of all stack
manipulations which means that the stack maps it assigns are much more
precise.
