From: Maciej Cencora Date: Thu, 16 Apr 2009 15:50:13 +0000 (+0200) Subject: r300: cleanup frag prog setup a little X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d7d5c97a215e6845ffa9fc60cee52da6a2d3148a;p=mesa.git r300: cleanup frag prog setup a little Use proper fields for marking if fp is translated, and if is translated succesfully. Now if fp gets translated (even unsuccesfully) fp->translated is true. If the translation failed (i.e. because we exceeded limit of maximum texture indirections) the fp->error is set. With a little updated fallback function it prevents non native fragment programs from beeing translated with every frame (the translation would fail anyway so there's no point to try again). Also implement IsProgramNative function for GL_FRAGMENT_PROGRAM_ARB (it should give some performance boost in apps that checks if program is native and falls back to simpler shader to meet hw limits if necessary) and cleanup indentation (remove whitespaces on empty lines). --- diff --git a/src/mesa/drivers/dri/r300/r300_fragprog.c b/src/mesa/drivers/dri/r300/r300_fragprog.c index 32182bb6674..f2d7cec5d36 100644 --- a/src/mesa/drivers/dri/r300/r300_fragprog.c +++ b/src/mesa/drivers/dri/r300/r300_fragprog.c @@ -175,7 +175,7 @@ static GLboolean transform_TEX( inst.SrcReg[0].File = PROGRAM_TEMPORARY;
