X-Git-Tag: upstream/18.1.0~256
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c7e3d31b0b5f22299a6bd72655502ce8427b40bf;p=platform%2Fupstream%2Fmesa.git

glsl: fix compat shaders in GLSL 1.40

The compatibility and core tokens were not added until GLSL 1.50,
for GLSL 1.40 just assume all shaders built with a compat profile
are compat shaders.

Fixes rendering issues in Dawn of War II on radeonsi which has
enabled OpenGL 3.1 compat support.

Fixes: a0c8b49284ef "mesa: enable OpenGL 3.1 with ARB_compatibility"
