Vulkan: Drop RelaxedPrecision from aliased attributes Take the following example: attribute mediump vec4 a; // location 0 attribute highp vec2 b; // location 0 f(b) This was previously translated to: attribute mediump vec4 a; // location 0 f(a.xy) That difference here is that b was previously highp, but a.xy is mediump. This change drops RelaxedPrecision from attributes so that they are all highp. Note that the temporary SPIR-V ids these attributes are loaded into still retain their RelaxedPrecision decoration (if any), and the precision of calculations in the shader is not increased by this change.
