Subject: i965: fix jump count on sandybridge
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c5a3b25bb954db49dcb5e7737018979782d2edba;hp=9c39a9fcb2c76897e9b5aff68ce197a411c4e25c;p=mesa.git

i965: fix jump count on sandybridge

Jump count is for 64bit long each, so one instruction requires 2
like on Ironlake.
