Subject: radeonsi: decrease maximum supported GENERIC varying index from 42 to 31
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1c99a13f89b743cbe4328a1c2cfc854dca05184d;p=mesa.git

radeonsi: decrease maximum supported GENERIC varying index from 42 to 31

This can decrease LDS and/or memory usage for shader outputs when geometry
shaders or tessellation is used.

Only PS inputs support higher indices and those aren't eliminated by
kill_outputs.
