[PATCH] D105742: [AMDGPU] Make some VOP1 instructions rematerializable

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec updated this revision to Diff 358095.
rampitec retitled this revision from "[AMDGPU] Make V_CVT_I32_F64/V_CVT_F64_I32 rematerializable." to "[AMDGPU] Make some VOP1 instructions rematerializable".
rampitec added a comment.

- Make more VOP1 rematerializable.
- Added instructions with SDWA and verified SDWA handling (unused_preserve cannot be rematerialized).
- Dropped old logic to specifically list and handle move instructions, it is covered by the new more generic code.
