Subject: i965/fs: mark last DF uniform array element as 64 bit live one
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7427425247d80c9f59a3c3ad2dfeeb2429de6f67;p=mesa.git

i965/fs: mark last DF uniform array element as 64 bit live one

This bug can make that we don't detect the end of a contiguous area
correctly and push larger areas than the real ones.
