Subject: pan/bi: Move bi_registers to common IR structures
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=79f30d8a86e9f9fe0f542c75f8ebf2e617f13135;p=mesa.git

pan/bi: Move bi_registers to common IR structures

Port assignments are critical to scheduling, this can't just live in
bi_pack.
