Subject: freedreno/ir3: number instructions from one
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4a7a6c9ef0eb6b26d8410591353142207689d085;p=mesa.git

freedreno/ir3: number instructions from one

ra_block_compute_live_ranges() treats zero as "not yet defined", so
probably best to not let this be a valid instruction #
