It certainly makes the code prettier: >00000ce0 <fbFetchPixel_x8r8g8b8>: > ce0: 8b 04 90 mov (%eax,%edx,4),%eax > ce3: 0d 00 00 00 ff or $0xff000000,%eax > ce8: c3 ret > ce9: 8d b4 26 00 00 00 00 lea 0x0(%esi),%esi Obviously a candidate for inlining too. _______________________________________________ Devel mailing list [email protected] http://mailman.laptop.org/mailman/listinfo/devel
