From 292eecca8c4284cbb343d954b76586fcaa26de2a Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Wed, 23 Jun 2010 09:19:18 -0600 Subject: [PATCH] draw: mask off DRAW_PIPE_FLAG_MASK bits in prim decompose code Any elt may potentially have flags bits set so mask off those bits everywhere. Fixes crashes with demos/gamma.c, redbook/polys.c, etc. but polygon stippling is still broken. --- src/gallium/auxiliary/draw/draw_pipe.c | 50 +++++++++++++++++----------------- 1 file changed, 25 insertions(+), 25 deletions(-) diff --git a/src/gallium/auxiliary/draw/draw_pipe.c b/src/gallium/auxiliary/draw/draw_pipe.c index 83556f1..a8b9dc6 100644 --- a/src/gallium/auxiliary/draw/draw_pipe.c +++ b/src/gallium/auxiliary/draw/draw_pipe.c @@ -177,15 +177,15 @@ static void do_triangle( struct draw_context *draw, ( DRAW_PIPE_RESET_STIPPLE | \ DRAW_PIPE_EDGE_FLAG_0 | \ DRAW_PIPE_EDGE_FLAG_1 ), \ - verts + stride * elts[i0], \ - verts + stride * elts[i1], \ - verts + stride * elts[i2]); \ + verts + stride * (elts[i0] & ~DRAW_PIPE_FLAG_MASK), \ + verts + stride * (elts[i1] & ~DRAW_PIPE_FLAG_MASK), \ + verts + stride * (elts[i2] & ~DRAW_PIPE_FLAG_MASK)); \ do_triangle( draw, \ ( DRAW_PIPE_EDGE_FLAG_1 | \ DRAW_PIPE_EDGE_FLAG_2 ), \ - verts + stride * elts[i0], \ - verts + stride * elts[i2], \ - verts + stride * elts[i3]) + verts + stride * (elts[i0] & ~DRAW_PIPE_FLAG_MASK), \ + verts + stride * (elts[i2] & ~DRAW_PIPE_FLAG_MASK), \ + verts + stride * (elts[i3] & ~DRAW_PIPE_FLAG_MASK)) /* emit last quad vertex as last vertex in triangles */ #define QUAD_LAST_PV(i0,i1,i2,i3) \ @@ -193,15 +193,15 @@ static void do_triangle( struct draw_context *draw, ( DRAW_PIPE_RESET_STIPPLE | \ DRAW_PIPE_EDGE_FLAG_0 | \ DRAW_PIPE_EDGE_FLAG_2 ), \ - verts + stride * elts[i0], \ - verts + stride * elts[i1], \ - verts + stride * elts[i3]); \ + verts + stride * (elts[i0] & ~DRAW_PIPE_FLAG_MASK), \ + verts + stride * (elts[i1] & ~DRAW_PIPE_FLAG_MASK), \ + verts + stride * (elts[i3] & ~DRAW_PIPE_FLAG_MASK)); \ do_triangle( draw, \ ( DRAW_PIPE_EDGE_FLAG_0 | \ DRAW_PIPE_EDGE_FLAG_1 ), \ - verts + stride * elts[i1], \ - verts + stride * elts[i2], \ - verts + stride * elts[i3]) + verts + stride * (elts[i1] & ~DRAW_PIPE_FLAG_MASK), \ + verts + stride * (elts[i2] & ~DRAW_PIPE_FLAG_MASK), \ + verts + stride * (elts[i3] & ~DRAW_PIPE_FLAG_MASK)) #define TRIANGLE(flags,i0,i1,i2) \ do_triangle( draw, \ @@ -218,7 +218,7 @@ static void do_triangle( struct draw_context *draw, #define POINT(i0) \ do_point( draw, \ - verts + stride * elts[i0] ) + verts + stride * (elts[i0] & ~DRAW_PIPE_FLAG_MASK) ) #define FUNC pipe_run #define ARGS \ @@ -296,14 +296,14 @@ void draw_pipeline_run( struct draw_context *draw, DRAW_PIPE_EDGE_FLAG_0 | \ DRAW_PIPE_EDGE_FLAG_1 ), \ verts + stride * ((i0) & ~DRAW_PIPE_FLAG_MASK), \ - verts + stride * (i1), \ - verts + stride * (i2)); \ + verts + stride * ((i1) & ~DRAW_PIPE_FLAG_MASK), \ + verts + stride * ((i2) & ~DRAW_PIPE_FLAG_MASK)); \ do_triangle( draw, \ ( DRAW_PIPE_EDGE_FLAG_1 | \ DRAW_PIPE_EDGE_FLAG_2 ), \ verts + stride * ((i0) & ~DRAW_PIPE_FLAG_MASK), \ - verts + stride * (i2), \ - verts + stride * (i3)) + verts + stride * ((i2) & ~DRAW_PIPE_FLAG_MASK), \ + verts + stride * ((i3) & ~DRAW_PIPE_FLAG_MASK)) /* emit last quad vertex as last vertex in triangles */ #define QUAD_LAST_PV(i0,i1,i2,i3) \ @@ -312,31 +312,31 @@ void draw_pipeline_run( struct draw_context *draw, DRAW_PIPE_EDGE_FLAG_0 | \ DRAW_PIPE_EDGE_FLAG_2 ), \ verts + stride * ((i0) & ~DRAW_PIPE_FLAG_MASK), \ - verts + stride * (i1), \ - verts + stride * (i3)); \ + verts + stride * ((i1) & ~DRAW_PIPE_FLAG_MASK), \ + verts + stride * ((i3) & ~DRAW_PIPE_FLAG_MASK)); \ do_triangle( draw, \ ( DRAW_PIPE_EDGE_FLAG_0 | \ DRAW_PIPE_EDGE_FLAG_1 ), \ verts + stride * ((i1) & ~DRAW_PIPE_FLAG_MASK), \ - verts + stride * (i2), \ - verts + stride * (i3)) + verts + stride * ((i2) & ~DRAW_PIPE_FLAG_MASK), \ + verts + stride * ((i3) & ~DRAW_PIPE_FLAG_MASK)) #define TRIANGLE(flags,i0,i1,i2) \ do_triangle( draw, \ flags, /* flags */ \ verts + stride * ((i0) & ~DRAW_PIPE_FLAG_MASK), \ - verts + stride * (i1), \ - verts + stride * (i2)) + verts + stride * ((i1) & ~DRAW_PIPE_FLAG_MASK), \ + verts + stride * ((i2) & ~DRAW_PIPE_FLAG_MASK)) #define LINE(flags,i0,i1) \ do_line( draw, \ flags, \ verts + stride * ((i0) & ~DRAW_PIPE_FLAG_MASK), \ - verts + stride * (i1)) + verts + stride * ((i1) & ~DRAW_PIPE_FLAG_MASK)) #define POINT(i0) \ do_point( draw, \ - verts + stride * i0 ) + verts + stride * ((i0) & ~DRAW_PIPE_FLAG_MASK) ) #define FUNC pipe_run_linear #define ARGS \ -- 2.7.4
