Subject: [PATCH 0/5] teach memory simplification about ASM instructions
Date: Sun, 21 Feb 2021 23:34:47 +0100 [thread overview]
Message-ID: <20210221223452.8075-1-luc.vanoostenryck@gmail.com> (raw)
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
