Description

Created attachment 141854 Test shader

In GLSL versions 1.00 ES, 1.10 and 1.20, Mesa includes some built-in functions which shouldn't be present in that version, namely:

genIType abs(genIType x) genIType sign(genIType x) genIType min(genIType x, genIType y) genIType min(genIType x, int y) genIType max(genIType x, genIType y) genIType max(genIType x, int y) genIType clamp(genIType x, genIType minVal, genIType maxVal) genIType clamp(genIType x, int minVal, int maxVal) genType trunc(genType x) genType round(genType x) genType roundEven(genType x) genType modf(genType x, out genType i)

I attached a shader that defines all these functions. It compiles with glslang for every GLSL version, but not with Mesa for GLSL version <=1.20
