Tomasz Figa fd0cf2c946 glsl: Allow precision mismatch on dead data with GLSL ES 1.00 ... Commit 259fc50545 added linker error for mismatching uniform precision, as required by GLES 3.0 specification and conformance test-suite. Several Android applications, including Forge of Empires, have shaders which violate this rule, on a dead varying that will be eliminated. The problem affects a big number of applications using Cocos2D engine and other GLES implementations accept this, this poses a serious application compatibility issue. Starting from GLSL ES 3.0, declarations with conflicting precision qualifiers are explicitly prohibited. However GLSL ES 1.00 does not clearly specify the behavior, except that "Uniforms are defined to behave as if they are using the same storage in the vertex and fragment processors and may be implemented this way. If uniforms are used in both the vertex and fragment shaders, developers should be warned if the precisions are different. Conversion of precision should never be implicit." The word "used" is not clear in this context and might refer to 1) declared (same as GLES 3.x) 2) referred after post-processing, or 3) linked after all optimizations are done. Looking at existing applications, 2) or 3) seems to be widely adopted. To avoid compatibility issues, turn the error into a warning if GLSL ES version is lower than 3.0 and the data is dead in at least one of the shaders.
