[PATCH] D111317: [DebugInfo][InstrRef] Track instructions that write-to-stack after having a spill fused into them

[Jeremy Morse via Phabricator via llvm-commits]

jmorse updated this revision to Diff 381803.
jmorse added a comment.

... and while I'm here, we should substitute instruction numbers when loads are folded into an instruction. See the added test memory-operand-load-folding.mir where the CVTTSS2SIrr (convert single precision number to signed int?) has a load folded into it. The instruction number should be preserved (with a substitution) for the sake of the value the instruction defines.
