Subject: i965/vp: Fix crashes with INTEL_DEBUG=vs.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1db9a72351e15d826950fab45889cdabb54c80b4;p=mesa.git

i965/vp: Fix crashes with INTEL_DEBUG=vs.

The VP generation doesn't set up the output reg strings, so if you
didn't happen to get these values as 0 on the stack, you'd lose.
