[AMDGPU][True16][MC] true16 for v_minmax/maxmin_f16 #119586

broxigarchen · 2024-12-11T16:45:40Z

Support true16 format for v_minmax/maxmin_f16 in MC.

Since we are replacing v_minmax/maxmin_f16 to v_minmax/maxmin_f16_t16 / v_minmax/maxmin_f16_fake16 in Post-GFX11, have to update the CodeGen pattern for v_minmax/maxmin_f16 to get CodeGen test passing.

Hi Jay Thanks for pointing this out. Revert this commit here #120594

#120594) This reverts commit e0526b0. The `v_minmax/maxmin_f16`(GFX11) needs to be updated to t16 with `v_minmax/maxmin_num_f16`(GFX12) together since they share the same codegen pattern. Revert the old patch and resubmit
