Subject: i965: clip: Move header_regs into brw_clip_compile.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5a93019a873d4388e80b334982d535c23bbd607f;p=mesa.git

i965: clip: Move header_regs into brw_clip_compile.

This makes header_regs available for computing VUE offsets within clip code.
