Doug Coleman 4c6435934b compiler.cfg.stacks.vacant: Fix docs for word rename. 2014-09-08 17:48:22 -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.
