[PATCH] D110937: [AMDGPU][GlobalISel] Select v_fma_mix_f32 and v_mad_mix_f32

[Mirko Brkusanin via Phabricator via llvm-commits]

mbrkusanin updated this revision to Diff 379650.
mbrkusanin added a comment.

Updated IgnoreCopy matcher to skip through multiple copies.

IR has matchers like m_TruncOrSelf and m_ZExtOrSelf which match one or zero of those nodes. So I guess it's not unprecedented to have a matcher like this.
Maybe rename to m_CopyOrSelf?
