[0/5] teach memory simplification about ASM instructions

Message

Luc Van Oostenryck Feb. 21, 2021, 10:34 p.m. UTC

This series fixes simplify_memops() which didn't took in account the
fact that ASM instructions can also modify the content of the memory:
either because it contains an output memory operand, or because
it explicetly clobbers memory in some other way.

Luc Van Oostenryck (5):
  reorg dominates()
  asm-mem: add testcase for missing reload after asm memops
  asm-mem: does it clobber memory?
  asm-mem: does it output to memory?
  asm-mem: teach dominates() about OP_ASM
