[PATCH] D121415: [FunctionAttrs] Infer argmemonly .

[Adam D'Andrea via Phabricator via llvm-commits]

akdandrea added a comment.

Seeing a test-suite failure for benchmark `SingleSource/Benchmarks/Linpack/linpack-pc.test` with `-flto`.  This is not being seen without LTO.
The failing output I'm seeing is as follows:

  ...Linux_LTO.220324/test-suite-build-2022-03-24_14-28-44/tools/fpcmp-target: Compared: 5.949578e+05 and 1.600000e+00
  abs. diff = 5.949562e+05 rel.diff = 3.718476e+05
  Out of tolerance: rel/abs: 1.000000e-04/0.000000e+00

Reverting this commit allows it to pass.

@fhahn let me know if you need more details to reproduce
