From 94e82b2e6cabd7ad26ff35067f6b6675168649d3 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 13 Nov 2012 14:40:22 -0800 Subject: [PATCH] mesa: Fix linker-assigned varying component counting since 8fb1e4a462 The goal of that change was to skip counting things that aren't actually outputs from the VS to the FS. However, explicit_location isn't set in the case of linker-assigned locations (the common case), so basically varying component counting got disabled. At this stage of the linker, we've already ensured that var->location is set, so we can just look at it without worrying. Fixes i965 assertion failure with the new piglit glsl-max-varyings --exceed-limits.
