Subject: i965/vec4: Pass dst register to the vec4_instruction constructor.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=16b911257440afbd77a6eb762e28df62e3c19bc7;p=mesa.git

i965/vec4: Pass dst register to the vec4_instruction constructor.

So regs_written gets initialized with a sensible value.
