[Mesa-dev] [PATCH v2 0/4] Rewrite the register-based into-SSA pass to use the phi builder API

[Jason Ekstrand]

This is a quick v2 of the regs_to_ssa rewrite.  Immediately after sending
it out and asking Rob and Eric to test it because we didn't use it for
anything with control-flow, I realized I could easily test it by hacking
our driver to call regs_to_ssa immediately after going out of SSA and then
go out of SSA again.  When I did, I found bugs.  This version has those
bugs fixed and passes Jenkins with that hack and another to silently ignore
indirects on registers.

Jason Ekstrand (4):
  nir: Rename convert_to_ssa lower_regs_to_ssa
  nir: Add foreach_register helper macros
  nir/phi-builder: Set the value in the block when creating a phi
  nir: Rewrite lower_regs_to_ssa to use the phi builder
