Subject: Used GCC's __builtin_expect when available.  Change the way code is
X-Git-Tag: 062012170305~23589
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=990dec7ea0ad9eca8340d39fd022baa151c05a03;p=profile%2Fivi%2Fmesa.git

Used GCC's __builtin_expect when available.  Change the way code is
generated for commands that can use RenderLarge packets.  Tweak the code for
__glXFlushRenderBuffer slightly.
