[PATCH] D134809: [AMDGPU][MC][GFX11] Disable non-null src0 for s_waitcnt_*cnt

[Dmitry Preobrazhensky via Phabricator via llvm-commits]

dp added a comment.

As an afterthought, I think this instruction will unlikely exist in future architectures (at least in the current form). I believe src0 will be either removed or repurposed.
