[PATCH] D144033: [AMDGPU][MC][GFX11] Add partial NSA format for image sample instructions

[Mirko Brkusanin via Phabricator via llvm-commits]

mbrkusanin added a comment.

Same could be done for GFX10, however differences between GFX10.1 and GFX10.3 cause inconveniences. 
MaxNSA size for 10.1 is 5 and for 10.3 is 13 so _V6, _V7,... opcodes for GFX10 already exist where every vaddr is a VGPR_32. 
We would need new versions exclusive for non-10.3.

Not sure if that is the best approach. We would end up with opcodes like:
IMAGE_SAMPLE_D_V1_V6_nsa_gfx10
IMAGE_SAMPLE_D_V1_V6_partial_nsa_gfx10
or
IMAGE_SAMPLE_D_V1_V6_nsa_gfx1030
IMAGE_SAMPLE_D_V1_V6_nsa_gfx1010
or
IMAGE_SAMPLE_D_V1_V6_nsa_navi2_gfx10
IMAGE_SAMPLE_D_V1_V6_nsa_navi1_gfx10
