| * | win: libm: add implementation for round/fmin/fmax and variants | Avi Halachmi (:avih) | 2015-11-07 | 1 | -0/+113 |
| | | | | | | | | | | | | | | | | | | | | | round and fmin/fmax are relatively commonly used functions but were not implemented anywhere in the tcc Windows distribution package. Newer mingw(64) math.h stil doesn't include these implementations. Add C implementations for these functions and place it as inline functions at win32/include/tcc/tcc_libm.h - which is already included from math.h . The code is mostly taken from musl-libc rs-1.0 (MIT) [*], musl-libc: http://git.musl-libc.org/cgit/musl/tree/src/math?h=rs-1.0 license: http://git.musl-libc.org/cgit/musl/tree/COPYRIGHT?h=rs-1.0 Potential enhancements: - Check how many useful libm implementations are still missing and consider adding them (some of them already work via the MS runtime). - Consider putting libm implementations in an actual libm.a file, or add a dummy one such that build processes which try to link with libm will not fail. | ||||
| * | win: math.h: fix fpclassify/signbit/etc - use C instead of broken asm | Avi Halachmi (:avih) | 2015-11-07 | 1 | -0/+88 |
| The asm code cannot currently be used with tcc since tcc doesn't support 't' constraint. Use inline C implementation instead, place it win32/include/tcc/tcc_libm.h, and include it from win32/include/math.h. Since fpclassify now works, it also fixes few other macros which depend on it. Implicitly fixed: isfinite, isinf, isnan, isnormal. The implementations were taken from musl-libc rs-1.0 (MIT license). musl-libc: http://git.musl-libc.org/cgit/musl/tree/src/math?h=rs-1.0 license: http://git.musl-libc.org/cgit/musl/tree/COPYRIGHT?h=rs-1.0 | |||||
