* sys/time.h: Change visibility of gettimeofday.Corinna Vinschen2016-06-201-1/+2
| | | | | | | gettimeofday is currently guarded with __MISC_VISIBLE || __XSI_VISIBLE. However, gettimeofday should be always visible, as in GLibc. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* math.h: Replace usage of INT_MAX with __INT_MAX__Corinna Vinschen2016-05-311-2/+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>
* Feature test macros: ctermid, cuseridYaakov Selkowitz2016-05-232-3/+13
| | | | | | | | | | The proper location for these functions has always been <stdio.h>, however XPG4 and SUSv2 did mandate a duplicate declaration in <unistd.h>. cuserid was dropped in SUSv3 (it was marked legacy since XPG4) and the ctermid declaration in <unistd.h> was made optional and obsolete in SUSv4.

* Make sure to have full configuration info in sys/_types.h.Corinna Vinschen2016-05-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | The following testcase: $ cat > test.c <<EOF #include <sys/select.h> #include <sys/time.h> EOF $ gcc -c test.c emits the following error: /usr/include/sys/reent.h:276:3: error: expected specifier-qualifier-list befor e ‘_fpos64_t’ _fpos64_t _EXFNPTR(_seek64, (struct _reent *, _PTR, _fpos64_t, int)); ^ The reason is that the load order from sys/select.h includes sys/_types.h before sys/config.h has been included from anywhere else. sys/_types.h defines _fpos64_t only if __LARGE64_FILES is defined, but it never is in this scenario. So sys/_types.h has to make sure to get the configuration info by itself. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

| | | | | | | | | | | Resurrect <machine/_user_types.h> for use in <sys/types.h>. Newlib targets may provide an own version of <machine/types.h> in their machine directory to add custom user types for <sys/types.h>. Check the _SYS_TYPES_H header guard to prevent a direct include of <machine/types.h>, since the <machine/types.h> file is a Newlib speciality.

* Provide __size_t via <sys/_types.h>Sebastian Huber2016-04-152-2/+17
| | | | | | | | | | | | | | | | | | | | | Various FreeBSD source and header files need a typedef __size_t via <sys/_types.h>. Unfortunately the GCC provided <stddef.h> uses #if (defined (__FreeBSD__) && (__FreeBSD__ >= 5)) \ || defined(__DragonFly__) \ || defined(__FreeBSD_kernel__) /* __size_t is a typedef on FreeBSD 5, must not trash it. */ #elif defined (__VMS__) /* __size_t is also a typedef on VMS. */ #else #define __size_t #endif and therefore defines __size_t on Newlib targets which would trash a __size_t typedef. Include <stddef.h> before <sys/_types.h> in <sys/types.h> and undefine __size_t in <sys/_types.h> as a workaround. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>

| | | | | | | | | | | | | | | | | | | | | | Newlib defines defaults for internal types via <sys/_types.h> and uses <machine/_types.h> to let targets define their own type if necessary. Previously for example #ifndef __dev_t_defined typedef short __dev_t; #endif However, the __*_t_defined pattern conflicts with the glibc type guard pattern for user types, e.g. dev_t in this example. Introduce a __machine_*_t_defined pattern for internal types (defined by <machine/_types.h>, used by <sys/_types.h>). For example #ifndef __machine_dev_t_defined typedef short __dev_t; #endif Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
* Feature test macros overhaul: string.h and strings.h overlapsYaakov Selkowitz2016-04-132-7/+12

* Eliminate use of Newlib-specific <machine/types.h>Sebastian Huber2016-04-139-35/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change solves a glibc/BSD compatibility problem. glibc and BSD use double underscore types for internal types. The Linux port of Newlib uses some glibc provided internal type definitions which are not protected by guard defines, e.g. __off_t. To avoid a conflict Newlib uses single underscore types for some internal types, e.g. _off_t. However, for BSD compatibility we have to define the internal types with double underscore names in <sys/_types.h>. The header file <machine/types.h> is Newlib-specific. It was used instead of <sys/_types.h> to provide the internal type definitions _CLOCK_T, _TIME_T_, _CLOCKID_T_, _TIMER_T_, and __suseconds_t. Move these definitions to <sys/_types.h> (there exist two instances of this file, one for Linux and one for all other targets). This makes the _HAVE_SYSTYPES configuration define obsolete (could possibly break the __RDOS__ target). Use the standard <sys/_types.h> include throughout. Move __loff_t defintion to default (non-Linux) <sys/_types.h>. Define it via _off64_t to avoid a dependency on the compiler. Provide the __off_t definition via default (non-Linux) <sys/_types.h> based on _off_t for all systems except Cygwin. For Cygwin use _off64_t. Define off_t via __off_t. Provide the __pid_t definition via default (non-Linux) <sys/_types.h>. This prevents a potential __pid_t and pid_t incompatibility. Add BSD guard defines for pid_t.

| | | | | | | | | | | | | | | | | | | | | | | 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.

* 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>

| | | | | | | | | | | | | | | | 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.

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.
