[Mesa-dev] [PATCH 0/7] precision qualifiers for ir_variable

[Tapani Pälli]

Hi;

I rebased Iago's patches and fixed some issues that I saw. On top of it
is 2 patches that fix precision related ES 3.1 CTS errors.

Any comments appreciated. What should be included in validation seems a
bit vague in the specs and I did not include anything else than precision
since this is what CTS explicitly checks for. Also, I noticed that Mesa
sets INVALID_OPERATION error always when validation fails, I don't think
this is correct. Spec lists the cases when error should happen and
otherwise only the validation state should be changed, this is also how
CTS expects it to work.

Currently we fail almost all dEQP tests for separate shader objects, these
patches did not have any effect on dEQP. I believe changes from Gregory
Hainut will fix some of those issues.

Thanks;
