Andrea Di Biagio bbff24bad4 [llvm-mca] Add the ability to mark register reads/writes associated with dep-breaking instructions. NFCI ... This patch adds two new boolean fields: - Field `ReadState::IndependentFromDef`. - Field `WriteState::WritesZero`. Field `IndependentFromDef` is set for ReadState objects associated with dependency-breaking instructions. It is used by the simulator when updating data dependencies between registers. Field `WritesZero` is set by WriteState objects associated with dependency breaking zero-idiom instructions. It helps the PRF identify which writes don't consume any physical registers. llvm-svn: 342483		2018-09-18 15:00:06 +00:00
