Subject: i965: Actually check every primitive for cut index support.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9f7d5870a31bc9fab6c42acba4ae97e4f9bdb2b9;p=mesa.git

i965: Actually check every primitive for cut index support.

can_cut_index_handle_prims() was passed an array of _mesa_prim objects
and a count, and ran a loop for that many iterations.  However, it
treated the array like a pointer, repeatedly checking the first element.

This patch makes it actually check every primitive.
