From: Ian Romanick Date: Sat, 6 Jan 2018 02:40:21 +0000 (-0800) Subject: glsl/linker: Mark no locations as invalid instead of marking all locations X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0c9df36157aca1e725f037e5adc54100aa387bd3;p=mesa.git glsl/linker: Mark no locations as invalid instead of marking all locations If max_index were ever 32, the linker would have marked all 32 locations as invalid instead of marking none of them as invalid. It's a good thing the maximum value actually set by any driver for MaxAttribs is 16. Found by inspection while investigating CID 1369628.
