* math: guard BSD finite/isinf/isnan functions properly in math.hYaakov Selkowitz2016-04-042-19/+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>

* cygwin: make POSIX/XSI version macros dependent on feature test macrosYaakov Selkowitz2016-04-041-10/+37
| | | | | | | | | | | | | Each version of SUS specifies a different value for _POSIX_VERSION, _POSIX2_VERSION, and _XOPEN_VERSION. glibc also changes the value of the other _POSIX2_ variables but not the _POSIX_* variables. _POSIX_TIMERS should be set to a version number, not just 1. The _POSIX_V7_* macros were missing, which was not noticed because the V6 values were aliased in sysconf (<unistd.h>). Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>

* Add missing long double functions to CygwinCorinna Vinschen2016-03-293-9/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Add simple versions of random() and srandom()Joel Sherrill2016-03-281-0/+6
| | | | | | | | | | | | | Prototypes also added for initstate() and setstate() but they were not implemented in the shared newlib code. * newlib/libc/include/cygwin/stdlib.h: Prototypes added. * winsup/cygwin/include/cygwin/stdlib.h: Prototypes removed. * newlib/libc/stdlib/random.c: New file. * newlib/libc/machine/epiphany/machine/stdlib.h: Removed * newlib/libc/stdlib/Makefile.am: Added random.c. * newlib/libc/stdlib/stdlib.tex: Added random.def. * newlib/libc/stdlib/Makefile.in: Regenerated.
* math.h: Use GCC builtins for C99 macros where availableCorinna Vinschen2016-03-261-19/+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.

| | | | | | | | | | | | | | | | | | | | | | | | u_char, u_short, u_int, u_long are BSD-only types. Remove them from Cygwin headers which are supposed to be used in a non-BSD scenario. Drop special Cygwin handling of those types in sys/types.h. newlib: * libc/include/sys/types.h (u_char,u_short,u_int,u_long): Drop Cygwin exception. cygwin: * fhandler_socket.cc (fhandler_socket::ioctl): Accommodate change in include/asm/socket.h. Continue using u_long since that's the MS type here. * include/asm/socket.h: Since the type given in _IOR/_IOW macros is only used for its sizeof, replace u_long with equivalent long. * netdb.h (getnetbyaddr): Fix prototype. * netinet/ip.h: Replace old BSD-only types with generically defined old BSD types (u_char -> u_int8_t, etc). * netinet/tcp.h: Ditto. * netinet/udp.h: Ditto.

* Feature test macros overhaul: C++ TR1Yaakov Selkowitz2016-03-231-5/+5
| | | | | | | | | | | | While C++11 was the first version of the standard to use C99 functionality, TR1 (for C++03) also does, and G++ does not distinguish between C++98 and C++03, or when TR1 is in use. Therefore, while not strictly correct for "pure" C++98, enabling C99 for all C++ usage is the simplest solution (and much better than always using -D_GNU_SOURCE as on Linux).

* Add arc4random() etc. from OpenBSD 5.8Sebastian Huber2016-03-183-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | According to the OpenBSD man page, "A Replacement Call for Random". It offers high quality random numbers derived from input data obtained by the OpenBSD specific getentropy() system call which is declared in <unistd.h> and must be implemented for each Newlib port externally. The arc4random() functions are used for example in LibreSSL and OpenSSH. Cygwin provides currently its own implementation of the arc4random family. Maybe it makes sense to use this getentropy() implementation: http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/lib/libcrypto/crypto/getentropy_win.c?rev=1.4&content-type=text/x-cvsweb-markup * libc/include/stdlib.h (arc4random): Declare if __BSD_VISIBLE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the complete rework of the feature tests macros for better compatibility with GNU libc, primarily based on the Linux man pages documentation: http://man7.org/linux/man-pages/man7/feature_test_macros.7.html The previous implementation was flawed in its approach that macros were often used to hide symbols if defined (e.g. !defined __STRICT_ANSI__ or !defined _POSIX_SOURCE), whereas the approach of glibc is that these macros make symbols available when defined (e.g. defined _BSD_SOURCE, or as used internally, #if __BSD_VISIBLE). As much open-source software is written with glibc in mind, this necessitated patching numerous packages just to compile. In particular, __STRICT_ANSI__ (which is defined by gcc -ansi or -std=c*) was given too much importance. This implementation limits the influence of __STRICT_ANSI__ to controlling the default when no other feature test macros are defined, and to the inclusion of <alloca.h> in <stdlib.h> as documented. These are the only places where __STRICT_ANSI__ should be tested. The following macros are now accepted: _ATFILE_SOURCE, _BSD_SOURCE, _DEFAULT_SOURCE, _ISOC99_SOURCE, _ISOC11_SOURCE, _LARGEFILE_SOURCE, _SVID_SOURCE, _XOPEN_SOURCE_EXTENDED. The existing __*_VISIBLE internal macros have been kept mostly compatible with the original BSD implementation, with some changes to the criteria which controls them. Several more macros in this style have been added where needed for concision or accuracy. Enabling C++11 or newer in the compiler also enables C99 and C11 functions. Doing so should help move away from the need to define _GNU_SOURCE in g++ for _GLIBCXX_USE_C99 support as on Linux: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51749 Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
