2017-04-17Remove legacy unions which are no longer usedJeff Johnston1-23/+0
- remove __fmath, __dmath, and __ldmath unions
2016-07-15math.h: fix guards on basic M_ constantsYaakov Selkowitz1-1/+1
MAXFLOAT, M_PI, and friends date back to at least XPG4v2, so this guard was incorrect even prior to the feature test macros overhaul. Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
2016-05-31math.h: Replace usage of INT_MAX with __INT_MAX__Corinna Vinschen1-2/+2
Using INT_MAX requires to include limits.h on most targets. Math.h must not rely on that. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2016-04-05math: update isinf/isnan function comments after move to math.hYaakov Selkowitz1-1/+1

2016-04-04math: guard BSD finite/isinf/isnan functions properly in math.hYaakov Selkowitz1-6/+19
Now that we have properly functioning feature test macros, the BSD floating-point classification functions can go into math.h instead of the non-standard ieeefp.h, and not under the C99 guard: http://man7.org/linux/man-pages/man3/finite.3.html The isnan function was in earlier versions of SUS but removed starting with POSIX.1-2001, compare: http://pubs.opengroup.org/onlinepubs/007908799/xsh/math.h.html http://pubs.opengroup.org/onlinepubs/009695399/basedefs/math.h.html Note that the isinf and isnan functions (but not the variants) conflict with functions by the same name in C++11, hence they (and only they) need to be hidden: https://sourceware.org/git/?p=glibc.git;a=commit;h=d9b965fa56350d6eea9f7f438a0714c7ffbb183f https://sourceware.org/git/?p=glibc.git;a=commit;h=3c47c83a9730c20e602694505b9278c25637b0d0 Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
2016-03-29Add missing long double functions to CygwinCorinna Vinschen1-4/+22
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. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2016-03-26math.h: Use GCC builtins for C99 macros where availableCorinna Vinschen1-19/+55
GCCs builtin functions are mostly type agnostic and architecture indepedent. Prefer to use them if available. * libc/include/math.h (fpclassify, isfinite, isinf, isnan, isnormal): Use matching GCC builtin functions if built with GCC 4.4 or later. (signbit): Use matching GCC builtin functions if built with GCC 4.0 or later. (isgreater, isgreaterequal, isless, islessequal, islessgreater, isunordered): Use matching GCC builtin functions if built with GCC 2.97 or later. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2016-03-17Feature test macros overhaul: math.hYaakov Selkowitz1-20/+23
Simplify the C99 conditionals. Mark the drem and gamma functions as BSD|SVID, the Bessel double functions also XSI and the floats also SUSv3. signgam is BSD|SVID|XSI, and matherr is SVID. Finally, use the internal macros to control the symbolic constants. Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
