Description Mark Janes 2016-06-06 20:13:38 UTC

mesa 505a8fbdf8f2b6d2aaab5a04244cd3329f9dbe97 fixed 24 dEQP tests and regressed 2 piglit tests.  

One of those tests, piglit.spec.arb_gpu_shader5.execution.built-in-functions.fs-ldexp, was fixed by a subsequent change to piglit.

The vertex shader ldexp test continues to fail on all platform IVB and later.  This failure should be designated as a regression or a piglit bug before the Mesa 12.0 release.

Matt, Ken suggests you might be able to take a quick look at this and determine if there is something wrong with the piglit test.

Whoops. Looks like I neglected to update the VS tests at the same time I fixed the FS ones.

I've pushed the following two commits

    arb_gpu_shader5: Remove out of spec ldexp() test case.
    
    Forgot to update the vs test in commit c8dfb932f.

    arb_gpu_shader5: Test ldexp(0.0f, non-zero-exp).
    
    Forgot to update the vs test in commit 5fae1a7ca4d.

which bring the vs test in line with the fs test.
