From 792e51b721491b19904e046124fb8c4c0e83f621 Mon Sep 17 00:00:00 2001 From: Corinna Vinschen Date: Mon, 28 Mar 2016 19:35:20 +0200 Subject: Add missing long double functions to Cygwin This patch adds the long double functions missing in newlib to Cygwin. Apart from some self-written additions (exp10l, finite{f,l}, isinf{f,l}, isnan{f,l}, pow10l) the files are taken from the Mingw-w64 math lib. Minor changes were required, e.g. substitue _WIN64 with __x86_64__ and fixing __FLT_RPT_DOMAIN/__FLT_RPT_ERANGE for Cygwin. Cygwin: * math: New subdir with math functions. * Makefile.in (VPATH): Add math subdir. (MATH_OFILES): List of object files collected from building files in math subdir. (DLL_OFILES): Add $(MATH_OFILES). ${CURDIR}/libm.a: Add $(MATH_OFILES) to build. * common.din: Add new functions from math subdir. * i686.din: Align to new math subdir. Remove functions now commonly available. * x86_64.din: Ditto. * math.h: math.h wrapper to define mingw structs used in some files in math subdir. * include/cygwin/version.h: Bump API minor version. newlib: * libc/include/complex.h: Add prototypes for complex long double functions. Only define for Cygwin. * libc/include/math.h: Additionally enable prototypes of long double functions for Cygwin. Add Cygwin-only prototypes for dreml, sincosl, exp10l and pow10l. Explain why we don't add them to newlib. * libc/include/tgmath.h: Enable long double handling on Cygwin.
