[Mesa-dev] [PATCH 0/5] NIR opcodes and constant folding

[Connor Abbott]

Hi,

This is a series I had floating around a while. The idea is to have all the
opcode stuff, including constant folding, derived from a single Python file.
I've cleaned it up a little by using {}-style Python formatting instead of the
pile of text-replacement and regular expressions we had before for getting the
constant expressions to a state where they could be compiled as C code.

Connor Abbott (5):
  nir: add generated file to .gitignore
  nir: use Python to autogenerate opcode information
  nir: add new constant folding infrastructure
  nir/constant_folding: use the new constant folding infrastructure
  nir/lower_vars_to_ssa: fix a bug with boolean constants
