Subject: i965: Move nir_lower_locals_to_regs a bit later.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b5e682a1efa0a929574e739807ac2b046e004561;p=mesa.git

i965: Move nir_lower_locals_to_regs a bit later.

I'm going to add a boolean scheduling pass that I want run late, but
after copy propagation and dead code elimination.  Yet, I don't want
to have to think about registers.  So, move the register conversion
a little later.

No impact on shader-db.  Suggested by Jason Ekstrand.
