[PATCH] D108727: [X86][MCA] Address other issues with MULX reported in PR51495.

[Andrea Di Biagio via Phabricator via llvm-commits]

andreadb added a comment.

@lebedev.ri I finally found out what the problem was. Luckily the fix was simple, and I was able to test it using your modified scheduling model.

That bug is fixed by this commit:

  [llvm] 1eb7536 - [MCA][RegisterFile] Consistently update the PRF in the presence of multiple writes to the same register.

Please let me know if that works for you too.

Apologies for all the issues caused by this change.

Thanks,
-Andrea
