Subject: ureg: add generic emitters for tex and branch instructions
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c23894295b593b9a8561e9775199e1c78ea4435d;p=mesa.git

ureg: add generic emitters for tex and branch instructions

Couldn't previously emit these except by calling the opcode-specific helper.
