[Bug 99343] dEQP-GLES31.functional.shaders.builtin_functions.precision.{min, max}.highp_compute.scalar failures

Bug ID: 99343 Summary: dEQP-GLES31.functional.shaders.builtin_functions.preci sion.{min,max}.highp_compute.scalar failures Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: samuel.pitoiset@gmail.com QA Contact: dri-devel@lists.freedesktop.org
Hi,
I have noticed that the following dEQP GLES31 tests fail with latest mesa/llvm:
dEQP-GLES31.functional.shaders.builtin_functions.precision.min.highp_compute.scalar dEQP-GLES31.functional.shaders.builtin_functions.precision.max.highp_compute.scalar
The same tests with lowp instead of highp work fine. Note that it's unrelated to compute because they also fail with vertex shaders.
After glancing at the code, it seems like enabling denorms for 32-bit floats fix them. But it's currently only enabled for 64-bit and 16-bit floats for some reasons.
Marek, Nicolai, any thoughts about that?
I didn't try if these tests pass with Catalyst though, but they do at least on NVIDIA hw.

--- Comment #1 from Marek Olšák maraeo@gmail.com --- Only VI can do FP32 denormals at full rate, which means only VI can enable them and not lose performance.
