[PATCH] D70400: [AMDGPU][GFX10] Disabled v_movrel*[sdwa|dpp] opcodes in codegen

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added a comment.

Actually what makes them risky is impuse of M0, so it can be folded around M0 definition. Isn't it cleaner to check for impuse in the SDWA and DPP combiner and disable the combining on these grounds rather than excluding it from codegen completely?
