From 3456f9149b3009fcfce80054759d05883d3c4ee5 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Mon, 7 Dec 2009 20:35:42 +0100 Subject: gallium/util: fix util_color_[un]pack[-ub] to be strict aliasing safe use pointer to union instead of void pointer. gcc complained a lot, depending what the pointer originally actually was. Looks like it's in fact maybe legal to cast for instance uint pointers to union pointers as long as union contains a uint type, hence use this with some callers, other just use union util_color in the first place. --- src/mesa/state_tracker/st_atom_pixeltransfer.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/mesa/state_tracker') diff --git a/src/mesa/state_tracker/st_atom_pixeltransfer.c b/src/mesa/state_tracker/st_atom_pixeltransfer.c index 4b35f59cc2..5e2ae1bb36 100644 --- a/src/mesa/state_tracker/st_atom_pixeltransfer.c +++ b/src/mesa/state_tracker/st_atom_pixeltransfer.c @@ -167,7 +167,7 @@ load_color_map_texture(GLcontext *ctx, struct pipe_texture *pt) ubyte g = ctx->PixelMaps.GtoG.Map8[i * gSize / texSize]; ubyte b = ctx->PixelMaps.BtoB.Map8[j * bSize / texSize]; ubyte a = ctx->PixelMaps.AtoA.Map8[i * aSize / texSize]; - util_pack_color_ub(r, g, b, a, pt->format, dest + k); + util_pack_color_ub(r, g, b, a, pt->format, (union util_color *)(dest + k)); } } -- cgit v1.2.3
