Technically 1 << 31 is undefined in C. Practically it works just fine. > > How about 1ull? That works too. FWIW I've always done ULL, not ull -- not sure what the mesa convention is. Oftentimes there are BIT() and BIT64() macros that abstract all this out, but I couldn't find them on a quick scan. -ilia _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
