Subject: mesa: Use VERT_{ATTRIB,BIT}* for ARB input validation.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b14c06e10d570edcb4dcbea173d71751563616e7;p=mesa.git

mesa: Use VERT_{ATTRIB,BIT}* for ARB input validation.

For validating ARB program inputs replace hard
coded bitfield and attribute number with the appropriate
VERT_{ATTRIB,BIT}* variant.

This should fix:
