From: Jonathan Marek Date: Wed, 8 May 2019 16:45:48 +0000 (-0400) Subject: nir: allow specifying a set of opcodes in lower_alu_to_scalar X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d0bff89159bead4ba850182e5a30d0745510f773;p=mesa.git nir: allow specifying a set of opcodes in lower_alu_to_scalar This can be used by both etnaviv and freedreno/a2xx as they are both vec4 architectures with some instructions being scalar-only.
