Subject: intel/fs: Move the scalar-region conversion to the generator.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c0504569eac5e5c305e9f0c240e248aca9d8891f;p=mesa.git

intel/fs: Move the scalar-region conversion to the generator.

Move the scalar-region conversion from the IR to the generator, so it
doesn't affect the Gen11 path. We need the non-scalar regioning
for a later lowering pass that we are adding.

v2: Better commit message (Matt)
