[PATCH] D110076: [AMDGPU][GlobalISel] Code quality: Combine V_RSQ

[Mateja Marjanovic via Phabricator via llvm-commits]

matejam updated this revision to Diff 390062.
matejam added a comment.

Added .ll test. Don't cover the G_FDIV + G_FSQRT case, only with rcp intrinsic (by the time it gets to the postlegalizer it will be transformed to that).
