Author: Jose Fonseca <[email protected]> Date: Sun Aug 9 11:25:41 2015 +0100 util: Cope with LONG_BIT not being defined on Windows. Neither MSVC nor MinGW defines LONG_BIT. For MSVC this was not a problem as it doesn't define __x86_64__ macro (it's GCC specific.) However on Windows long type is guaranteed to be 32bits. Also add an #error, as GCC will just warn, not throw any error, when no value is returned. Trivial. --- src/util/rounding.h | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/src/util/rounding.h b/src/util/rounding.h index b0c9918..ec31b47 100644 --- a/src/util/rounding.h +++ b/src/util/rounding.h @@ -96,8 +96,10 @@ _mesa_lroundevenf(float x) #ifdef __x86_64__ #if LONG_BIT == 64 return _mm_cvtss_si64(_mm_load_ss(&x)); -#elif LONG_BIT == 32 +#elif LONG_BIT == 32 || defined(_WIN32) return _mm_cvtss_si32(_mm_load_ss(&x)); +#else +#error "Unsupported or undefined LONG_BIT" #endif #else return lrintf(x); @@ -114,8 +116,10 @@ _mesa_lroundeven(double x) #ifdef __x86_64__ #if LONG_BIT == 64 return _mm_cvtsd_si64(_mm_load_sd(&x)); -#elif LONG_BIT == 32 +#elif LONG_BIT == 32 || defined(_WIN32) return _mm_cvtsd_si32(_mm_load_sd(&x)); +#else +#error "Unsupported or undefined LONG_BIT" #endif #else return lrint(x); _______________________________________________ mesa-commit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-commit
