Use native float math functions for MSVC12 `double` surrogates are slow (e.g. pow is 2x slower than powf), and MSVC12 supports fp-math functions from C99. =================================================================== M source/blender/blenlib/BLI_math_base.h =================================================================== diff --git a/source/blender/blenlib/BLI_math_base.h b/source/blender/blenlib/BLI_math_base.h index 5f94f04..494bc40 100644 --- a/source/blender/blenlib/BLI_math_base.h +++ b/source/blender/blenlib/BLI_math_base.h @@ -83,8 +83,8 @@ static const int NAN_INT = 0x7FC00000; # define NAN_FLT (*((float *)(&NAN_INT))) #endif -/* do not redefine functions from C99 or POSIX.1-2001 */ -#if !(defined(_ISOC99_SOURCE) || (defined(_POSIX_C_SOURCE) && _POSIX_C_SOURCE >= 200112L)) +/* do not redefine functions from C99, POSIX.1-2001 or MSVC12 (partial C99) */ +#if !(defined(_ISOC99_SOURCE) || (defined(_POSIX_C_SOURCE) && _POSIX_C_SOURCE >= 200112L) || (defined(_MSC_VER) && _MSC_VER >= 1800)) #ifndef sqrtf #define sqrtf(a) ((float)sqrt(a)) @@ -138,7 +138,7 @@ static const int NAN_INT = 0x7FC00000; #define copysignf(a, b) ((float)copysign(a, b)) #endif -#endif /* C99 or POSIX.1-2001 */ +#endif /* C99, POSIX.1-2001 or MSVC12 (partial C99) */ #ifdef WIN32 # if defined(_MSC_VER) _______________________________________________ Bf-blender-cvs mailing list [email protected] http://lists.blender.org/mailman/listinfo/bf-blender-cvs
