Subject: mesa: Don't advertise GLES 3.1 without compute support
X-Git-Url: https://git.libre-soc.org/?p=mesa.git;a=commitdiff_plain;h=1d628ea09df4911e897292186dc8242903c7a502

mesa: Don't advertise GLES 3.1 without compute support

The MaxComputeWorkGroupInvocations constant is used in
compute_version_es2() instead of extensions->ARB_compute_shader
as ES has lower requirements than desktop GL.

Both i965 and gallium set this constant before enabling compute support.
