[Mesa-dev] [PATCH 2/6] i965: Create prog_data temporary variables in PS state upload code.

Kenneth Graunke kenneth at whitecape.org
Mon Nov 24 22:03:11 PST 2014


prog_data->foo is a bit more readable than brw->wm.prog_data->foo.
The local variable definition is also a great location to put the
obligatory /* CACHE_NEW_WM_PROG */ comment.
