Subject: i965/sf: Drop useless push/pop state from flag register mashing code.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=41afb3ade46c9a10c7a1e61df55c7b51281b0247;p=mesa.git

i965/sf: Drop useless push/pop state from flag register mashing code.

There's no point in pushing and popping the default state; the code
between the two stack operations doesn't alter anything.
