Steps to reproduce: $ cd <deqp-home> $ cd modules/gles3 $ ./deqp-gles3 -n dEQP-GLES3.functional.shaders.builtin_functions.precision.sign.lowp_fragment.vec2 (...) Test run totals: Passed: 0/1 (0.0%) Failed: 1/1 (100.0%) Not supported: 0/1 (0.0%) Warnings: 0/1 (0.0%) The complete list of affected dEQP tests is: dEQP-GLES3.functional.shaders.builtin_functions.precision.sign.lowp_fragment.vec2 dEQP-GLES3.functional.shaders.builtin_functions.precision.sign.lowp_fragment.vec3 dEQP-GLES3.functional.shaders.builtin_functions.precision.sign.mediump_fragment.vec2 dEQP-GLES3.functional.shaders.builtin_functions.precision.sign.mediump_fragment.vec3 The commit that introduced the regression is: commit d91390634ff8c50b217d55372db186d03996e9f7 Author: Matt Turner <mattst88@gmail.com> Date: Fri Jan 23 21:58:51 2015 -0800 i965: Add LINTERP/CINTERP to can_do_cmod(). LINTERP is implemented as a PLN instruction or a LINE+MAC. PLN and MAC can do conditional mod. CINTERP is just a MOV. total instructions in shared programs: 5952103 -> 5950284 (-0.03%) instructions in affected programs: 324573 -> 322754 (-0.56%) helped: 1819 We lose the SIMD16 in one Unigine Heaven shader which appears six times in shader-db.
I'll send a patch shortly.
