Subject: i965/vec4: Add a brw->gen >= 6 assertion in three-source emitters.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ffde483f3c4da547f2823f72554cea1d1ff25e48;p=mesa.git

i965/vec4: Add a brw->gen >= 6 assertion in three-source emitters.

Three source instructions didn't exist until Gen6.  vec4_generator has
assertions to catch this, but catching it in the visitor provides a
nicer backtrace.
