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/gallium/auxiliary/util/u_clear.h | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'src/gallium/auxiliary/util/u_clear.h') diff --git a/src/gallium/auxiliary/util/u_clear.h b/src/gallium/auxiliary/util/u_clear.h index 1e65a035ae..2c32db6175 100644 --- a/src/gallium/auxiliary/util/u_clear.h +++ b/src/gallium/auxiliary/util/u_clear.h @@ -46,13 +46,13 @@ util_clear(struct pipe_context *pipe, { if (buffers & PIPE_CLEAR_COLOR) { struct pipe_surface *ps = framebuffer->cbufs[0]; - unsigned color; + union util_color uc; - util_pack_color(rgba, ps->format, &color); + util_pack_color(rgba, ps->format, &uc); if (pipe->surface_fill) { - pipe->surface_fill(pipe, ps, 0, 0, ps->width, ps->height, color); + pipe->surface_fill(pipe, ps, 0, 0, ps->width, ps->height, uc.ui); } else { - util_surface_fill(pipe, ps, 0, 0, ps->width, ps->height, color); + util_surface_fill(pipe, ps, 0, 0, ps->width, ps->height, uc.ui); } } -- cgit v1.2.3
