[Mesa-dev] [PATCH 0/8] nir: Fix and enable global code motion

[Jason Ekstrand]

This patch series has a bunch of fixes and refactors for the global code
motion pass in NIR.  The patch to dominance is needed for correctness while
most of the rest of them are just cleanups or exist to enable patch 7
without regressions.  With the exception of "Deus Ex: Mankind Divided", the
numbers are finally looking really good.

Jason Ekstrand (8):
  nir/dominance: Better handle unreachable blocks
  nir/gcm: Loop over blocks in pin_instructions
  nir/gcm: Use an array for storring the early block
  nir/gcm: Move block choosing into a helper function
  nir/gcm: Add a real concept of "progress"
  nir/gcm: Delete dead instructions
  nir/gcm: Prefer the instruction's original block
  i965/nir: Use GCM and GVN in the first run of nir_optimize
