Subject: r300/compiler: print stats based on the initial number of instructions
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c6ace30028a9b96cf9f26d82837760f4fc78f8e2;p=mesa.git

r300/compiler: print stats based on the initial number of instructions

The same number of shaders is now printed regardless of optimizations being
enabled or not, so that we can compare shader stats side by side easily.
