Seth Brenith 252acd7ffc Revert "Move branch inversion on ==0 into platform-agnostic reducer" ... This reverts commit 0c72c71900. Reason for revert: Wasm code size increase because not all pipelines use CommonOperatorReducer Original change's description: > Move branch inversion on ==0 into platform-agnostic reducer > > This change is based on a discussion from > https://crrev.com/c/v8/v8/+/2053769/4/src/compiler/machine-operator-reducer.cc#1696 > wherein Tobias suggested moving the folding away of ==0 operations out > of the platform-specific instruction selectors and into the > MachineOperatorReducer. I noticed that CommonOperatorReducer already > handles some very similar cases, so I have tried putting the ==0 folding > into CommonOperatorReducer instead. I'm happy to move it into > MachineOperatorReducer if that's better; I still don't have a very good > understanding of how roles are separated among reducers. > > Change-Id: Ia0285bd9fafeef29d87cc88654bd6d355d467e8f > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2076498 > Commit-Queue: Seth Brenith <seth.brenith@microsoft.com> > Reviewed-by: Tobias Tebbi <tebbi@chromium.org> > Reviewed-by: Clemens Backes <clemensb@chromium.org> > Reviewed-by: Georg Neis <neis@chromium.org> > Cr-Commit-Position: refs/heads/master@{#66688} # Not skipping CQ checks because original CL landed > 1 day ago.
