test case for piglit shader_runner
GLSL spec 1.20 section 4.6.1 mentions all output variables can be forced to be
invariant by:
#pragma STDGL invariant(all)
but the attached test case shows it doesn't take effect, which fails with below
error:
Failed to link:
error: vertex shader output `var' lacks invariant qualifier, but fragment
shader input has invariant qualifier
PIGLIT: {'result': 'fail' }
Tested on Piketon (i965) with mesa master.
