From: José Fonseca Date: Thu, 18 Jun 2009 13:46:45 +0000 (+0100) Subject: draw: Replace pointer arithmetic with cast. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=21bfd0f4bdd4222346c7f2db956e7fc1645d2130;p=mesa.git draw: Replace pointer arithmetic with cast. Using uintptr_t as intermediate type for pointer -> integer conversions is easier to understand and does not cause any size mismatch warnings. uintptr_t is part of C99, and we already provide a suitable replacement definition for all platforms we care about. --- diff --git a/src/gallium/auxiliary/draw/draw_pt_elts.c b/src/gallium/auxiliary/draw/draw_pt_elts.c index b7780fb5073..88f4d9f495a 100644 --- a/src/gallium/auxiliary/draw/draw_pt_elts.c +++ b/src/gallium/auxiliary/draw/draw_pt_elts.c @@ -54,7 +54,8 @@ static unsigned elt_ubyte( const void *elts, unsigned idx ) static unsigned elt_vert( const void *elts, unsigned idx ) { - return (const ubyte *)elts - (const ubyte *)NULL + idx; + /* unsigned index is packed in the pointer */ + return (unsigned)(uintptr_t)elts + idx; } pt_elt_func draw_pt_elt_func( struct draw_context *draw )
