[PATCH] D69172: AMDGPU: Fix SMEM WAR hazard for gfx10 readlane

[Jay Foad via Phabricator via llvm-commits]

foad added a comment.

Hi @kerbowa, why is this needed for gfx10? The public RDNA documentation says:

  4.5. Manually Inserted Wait States (NOPs)
  Inserting S_NOP is never required to achieve correct operation.

Is this not the full story?
