(In reply to Randy from comment #0) > dEQP-GLES31.functional.shaders.linkage.uniform.block.differing_precision.qpa: > <Result StatusCode="Fail">expected shaders to compile and link properly, but > failed to link.</Result> I have sent a couple of patches to fix it and open a discussion to see if this behaviour is intended or is a spec bug: allowing different precision qualifiers for block members in different definitions of the same shader interface is only allowed in GLSL ES 3.1. In older and newer (GLSL ES 3.2) specs the precision qualifiers should match. https://lists.freedesktop.org/archives/mesa-dev/2016-October/132494.html
Btw. Is there dEQP test for issue in bug 97804?
(In reply to Eero Tamminen from comment #3) > Btw. Is there dEQP test for issue in bug 97804? At first glance, I have not found any neither in dEQP GLES 3.1 nor GLES 3 tests :-(
Patches pushed to master: b50b82b glsl/es31: precision qualifier doesn't need to match in shader interface block members 849390a glsl: move intrastage_match() after interstage_member_mismatch()
