There were a bunch of lost debug location remarks that show up when legalizing tail calls on AArch64. This would happen because we drop the return in the block where we emit the tail call. So, we end up dropping the debug location, which makes the LostDebugLocObserver report a missing debug location. Although it's *true* that we lose these debug locations, this isn't a particularly useful remark. We expect to drop these debug locations when emitting tail calls. Suppressing remarks in this case is preferable, since the amount of noise could hide actual debug location related bugs. To do this, I just plumbed the LostDebugLocObserver through the relevant LegalizerHelper functions. This is the only case I can think of where we need the LostDebugLocObserver in the LegalizerHelper. So, rather than storing it in the LegalizerHelper proper and mucking around with the constructors, I figured it'd be cleanest to take the simplest path for now. This clears up ~20 noisy lost debug location remarks on CTMark in AArch64 at -Os. Differential Revision: https://reviews.llvm.org/D103128 |
