sorry, I was confused by the glewinfo which shows
GL_ARB_gpu_shader_fp64: OK [MISSING]
with and without your patches, but glxinfo gets it right.
This is on an RS780 (HD3200?) integrated gpu.
running:
# ./piglit-run.py --dmesg --abort-on-monitored-error -s -l verbose -1 -t
arb_gpu_shader_fp64 all results/fp64
gives ~70% crashes until the system hard locks (or reboots) at some point.
Maybe it had also problems before running some shaders, so it is not necessary
a result of your work.
Because this is a very old platform which will never be able to see GL4, I
don't take this result too serious.
I will redo the tests until it hard locks, so you can get at least a partial
result.
