Alistair Francis	aa706e13f4	Split up endian.h to minimize exposure of BYTE_ORDER. With only two exceptions (sys/types.h and sys/param.h, both of which historically might have defined BYTE_ORDER) the public headers that include <endian.h> only want to be able to test __BYTE_ORDER against ___ENDIAN. This patch creates a new bits/endian.h that can be included by any header that wants to be able to test __BYTE_ORDER and/or __FLOAT_WORD_ORDER against the ___ENDIAN constants, or needs __LONG_LONG_PAIR. It only defines macros in the implementation namespace. The existing bits/endian.h (which could not be included independently of endian.h, and only defines __BYTE_ORDER and maybe __FLOAT_WORD_ORDER) is renamed to bits/endianness.h. I also took the opportunity to canonicalize the form of this header, which we are stuck with having one copy of per architecture. Since they are so short, this means git doesn’t understand that they were renamed from existing headers, sigh. endian.h itself is a nonstandard header and its only remaining use from a standard header is guarded by __USE_MISC, so I dropped the __USE_MISC conditionals from around all of the public-namespace things it defines. (This means, an application that requests strict library conformance but includes endian.h will still see the definition of BYTE_ORDER.) A few changes to specific bits/endian(ness).h variants deserve mention: - sysdeps/unix/sysv/linux/ia64/bits/endian.h is moved to sysdeps/ia64/bits/endianness.h. If I remember correctly, ia64 did have selectable endianness, but we have assembly code in sysdeps/ia64 that assumes it’s little-endian, so there is no reason to treat the ia64 endianness.h as linux-specific. - The C-SKY port does not fully support big-endian mode, the compile will error out if __CSKYBE__ is defined. - The PowerPC port had extra logic in its bits/endian.h to detect a broken compiler, which strikes me as unnecessary, so I removed it. - The only files that defined __FLOAT_WORD_ORDER always defined it to the same value as __BYTE_ORDER, so I removed those definitions. The SH bits/endian(ness).h had comments inconsistent with the actual setting of __FLOAT_WORD_ORDER, which I also removed. - I removed copyright boilerplate from the few bits/endian(ness).h headers that had it; these files record a single fact in a fashion dictated by an external spec, so I do not think they are copyrightable. As long as I was changing every copy of ieee754.h in the tree, I noticed that only the MIPS variant includes float.h, because it uses LDBL_MANT_DIG to decide among three different versions of ieee854_long_double. This patch makes it not include float.h when GCC’s intrinsic __LDBL_MANT_DIG__ is available. * string/endian.h: Unconditionally define LITTLE_ENDIAN, BIG_ENDIAN, PDP_ENDIAN, and BYTE_ORDER.

Gabriel F. T. Gomes	d11086a939	ldbl-opt: Add error and error_at_line (bug 23984) On platforms where long double may have the same format as double (-mlong-double-64), error and error_at_line do not take that into account and might produce wrong output if a long double conversion is requested by the format string ('%Lf'). This patch adds compatibility functions for this situation and redirects calls via header magic. Tested for powerpc, powerpc64 and powerpc64le.	8 years ago
Gabriel F. T. Gomes	90188e7d1a	ldbl-opt: Add err, errx, verr, verrx, warn, warnx, vwarn, and vwarnx (bug 23984) When support for long double format with 128-bits (-mlong-double-128) was added for platforms where long double had the same format as double, such as powerpc, compatibility versions for the functions listed in the commit title were missed. Since the older format of long double can still be used (with -mlong-double-64), using these functions with a format string that requests the printing of long double variables will produce wrong outputs. This patch adds the missing compatibility functions and header magic to redirect calls to them when -mlong-double-64 is in use. Tested for powerpc, powerpc64 and powerpc64le.	8 years ago
Gabriel F. T. Gomes	6e1f6440b9	ldbl-opt: Add argp_error and argp_failure (bug 23983) The functions argp_error and argp_failure are missing support for printing long double values when long double has the same format as double. This patch adds the new functions __nldbl_argp_error and __nldbl_argp_failure, as well as header magic to redirect calls to them when -mlong-double-64 is in use. Tested for powerpc, powerpc64 and powerpc64le.	8 years ago

Florian Weimer	e47d82c99a	Provide <bits/unistd_ext.h> as a sysdeps header exclusively Non-sysdeps headers cannot be overriden by sysdeps headers across the entire build, so it is necessary to turn such extension headers into sysdeps headers themselves. The approach here follows the existing <bits/shm.h> header (although it uses sysdeps/gnu instead of sysdeps/generic).

Gabriel F. T. Gomes	1a502f5260	Add *-ldbl.h headers to include/bits On some platforms, long double may have either the same format as double or another, wider format, such as the Quadruple IEC 60559 long double format or the IBM Extended Precision format (both 128-bits wide). Selecting between the available formats is done by using one of the following compiler switches: -mlong-double-128, for the wider format, or -mlong-double-64, for the narrower. On all platforms that provide this choice, the wider format is the default. When the non-default format is selected by user code (i.e.: when building with -mlong-double-64) calls to functions that take long double parameters or return a long double type (e.g.: strfroml) are redirected to a compat function, via assembler redirection, by headers such as bits/stdlib-ldbl.h or bits/misc-ldbl.h. In glibc builds, however, these headers are currently being read from the system directories (/usr/include/bits) rather than from the source directory. Although this works correctly today, it raises reproducibility concerns. Besides that, builds for powerpc64le will need these files from the source directory, because on powerpc64le, the new redirections for long double with IEEE binary128 format will be implemented in these headers. Tested for powerpc64 and powerpc64le.	7 years ago

Joseph Myers	63716ab270	Add build infrastructure for narrowing libm functions. TS 18661-1 defines libm functions that carry out an operation (+ - * / sqrt fma) on their arguments and return a result rounded to a (usually) narrower type, as if the original result were computed to infinite precision and then rounded directly to the result type without any intermediate rounding to the argument type. For example, fadd, faddl and daddl for addition. These are the last remaining TS 18661-1 functions left to be added to glibc. TS 18661-3 extends this to corresponding functions for _FloatN and _FloatNx types. As functions parametrized by two rather than one varying floating-point types, these functions require infrastructure in glibc that was not required for previous libm functions. This patch provides such infrastructure - excluding test support, and actual function implementations, which will be in subsequent patches. Declaring the functions uses a header bits/mathcalls-narrow.h, which is included many times, for each relevant pair of types. This will end up containing macro calls of the form __MATHCALL_NARROW (__MATHCALL_NAME (add), __MATHCALL_REDIR_NAME (add), 2); for each family of narrowing functions. (The structure of this macro call, with the calls to __MATHCALL_NAME and __MATHCALL_REDIR_NAME there rather than in the definition of __MATHCALL_NARROW, arises from the names such as "add" not themselves being reserved identifiers - meaning it's necessary to avoid any indirection that would result in a user-defined "add" macro being expanded.) Whereas for existing functions declaring long double functions is disabled if _LIBC in the case where they alias double functions, to facilitate defining the long double functions as aliases of the double ones, there is no such logic for the narrowing functions in this patch. Rather, the files defining such functions are expected to use #define to hide the original declarations of the alias names, to avoid errors about defining aliases with incompatible types. math/Makefile support is added for building the functions (listed in libm-narrow-fns, currently empty) for all relevant pairs of types. An internal header math-narrow.h is added for macros shared between multiple function implementations - currently a ROUND_TO_ODD macro to facilitate writing functions using the round-to-odd implementation approach, and alias macros to create all the required function aliases. libc_feholdexcept_setroundf128 and libc_feupdateenv_testf128 are added for use when required (only for x86_64). float128_private.h support is added for ldbl-128 narrowing functions to be used for _Float128. Certain things are specifically omitted from this patch and the immediate followups. tgmath.h support is deferred; there remain unresolved questions about how the type-generic macros for these functions are supposed to work, especially in the case of arguments of integer type. The math.h / bits/mathcalls-narrow.h logic, and the logic for determining what functions / aliases to define, will need some adjustments to support the sqrt and fma functions, where e.g. f32xsqrtf64 can just be an alias for sqrt rather than a separate function. TS 18661-1 defines FP_FAST_* macros but no support is included for defining them (they won't in general be true without architecture-specific optimized function versions). For each of the function groups (add sub mul div sqrt fma) there are always six functions present (e.g. fadd, faddl, daddl, f32addf64, f32addf32x, f32xaddf64). When _Float64x and _Float128 are supported, there are seven more (e.g. f32addf64x, f32addf128, f64addf64x, f64addf128, f32xaddf64x, f32xaddf128, f64xaddf128). In addition, in the ldbl-opt case there are function names such as __nldbl_daddl (an alias for f32xaddf64, which is not a reserved name in TS 18661-1, only in TS 18661-3), for calls to daddl to be mapped to in the -mlong-double-64 case. (Calls to faddl just get mapped to fadd, and for sqrt and fma there won't be __nldbl_* functions because dsqrtl and dfmal can just be mapped to sqrt and fma with -mlong-double-64.) While there are six or thirteen functions present in each group (plus __nldbl_* names only as an ABI, not an API), not all are distinct; they fall in various groups of aliases. There are two distinct versions built if long double has the same format as double; four if they have distinct formats but there is no _Float64x or _Float128 support; five if long double has binary128 format; seven when _Float128 is distinct from long double. Architecture-specific optimized versions are possible, but not included in my patches. For example, IA64 generally supports narrowing the result of most floating-point instructions; Power ISA 2.07 (POWER8) supports double values as arguments to float instructions, with the results narrowed as expected; Power ISA 3 (POWER9) supports round-to-odd for float128 instructions, so meaning that approach can be used without needing to set and restore the rounding mode and test "inexact". I intend to leave any such optimized versions to the architecture maintainers. Generally in such cases it would also make sense for calls to these functions to be expanded inline (given -fno-math-errno); I put a suggestion for TS 18661-1 built-in functions at <https://gcc.gnu.org/wiki/SummerOfCode>.

Zack Weinberg	6c6c962a20	Post-cleanup 1: move libio.h back out of bits/. We can't go very far with libio cleanups as long as we still have _IO_MTSAFE_IO, and I am not tackling that in this patch series, but we can at least make the maze of stdio-related headers a little less complicated. In this patch, libio.h moves back out of bits/ into the top level of the libio subdirectory, and is merged with libio/bits/libio-ldbl.h (which also used to be installed) and include/libio.h. Since almost no files include libio.h directly, this is quite straightforward. libio.h is now always used with _LIBC defined, so all of the _LIBC \|\| _GLIBCPP_USE_WCHAR_T conditionals are unnecessary. Similarly, the ifdef nest surrounding the definition of _IO_fwide_maybe_incompatible can collapse down to a single SHLIB_COMPAT check. I also took the opportunity to add some checks for configuration botches to libio.h. Installed stripped libraries are unchanged by this patch. * libio/bits/libio.h: Move back to libio/libio.h and adjust multiple-include guard to match. Merge contents of libio/bits/libio-ldbl.h and include/libio.h into this file. Remove preprocessor conditionals that are always true and/or redundant to other preprocessor conditionals in the same nest. Include shlib-compat.h unconditionally. Error out if _LIBC is not defined, or if _ISOMAC is defined, or if _IO_MTSAFE_IO is defined but _IO_lock_t_defined is not defined after including stdio.h.

Zack Weinberg	a4fea3f2c3	Don't install libio.h or _G_config.h. We shipped 2.27 with libio.h and _G_config.h still installed but issuing warnings when used. Let's stop installing them early in 2.28 so that we have plenty of time to think of another plan if there are problems. The public stdio.h had a genuine dependency on libio.h for the complete definitions of FILE and cookie_io_functions_t, and a genuine dependency on _G_config.h for the complete definitions of fpos_t and fpos64_t; these are moved to single-type headers. bits/types/struct_FILE.h also provides a handful of accessor and bitflags macros so that code is not duplicated between bits/stdio.h and libio.h. All the other _IO_ and _G_ names used by the public stdio.h can be replaced with either public names or __-names. In order to minimize the risk of breaking our own compatibility code, bits/types/struct_FILE.h preserves the _IO_USE_OLD_IO_FILE mechanism exactly as it was in libio.h, but you have to define _LIBC to use it, or it'll error out. Similarly, _IO_lock_t_defined is preserved exactly, but will error out if used without defining _LIBC. Internally, include/stdio.h continues to include libio.h, and libio.h scrupulously provides every _IO_* and _G_* name that it always did, perhaps now defined in terms of the public names. This is how this patch avoids touching dozens of files throughout glibc and becoming entangled with the _IO_MTSAFE_IO mess. The remaining patches in this series eliminate most of the _G_ names. Tested on x86_64-linux; in addition to the test suite, I installed the library in a sysroot and verified that a simple program that uses stdio.h could be compiled against the installed library, and I also verified that installed stripped libraries are unchanged. * libio/bits/types/__fpos_t.h, libio/bits/types/__fpos64_t.h: New single-type headers split from _G_config.h. * libio/bits/types/cookie_io_functions_t.h * libio/bits/types/struct_FILE.h New single-type headers split from libio.h. * libio/Makefile: Install the above new headers.

Zack Weinberg	48a8f83281	Deprecate external use of libio.h and _G_config.h. libio.h was originally the header for a set of supported GNU extensions, but they have not been maintained as such in many years, they are now standing in the way of improvements to stdio, and we don't think there are any remaining external users. _G_config.h was never intended for public use, but predates the bits convention. Move both of these headers into the bits directory and provide stubs at top level which issue deprecation warnings. The contents of (bits/)libio.h and (bits/)_G_config.h are still exposed to external software via stdio.h; changing that requires more complex surgery than I have time to attempt right now. * libio/libio.h, libio/_G_config.h: New stub headers which issue a deprecation warning and then include <bits/libio.h>, <bits/_G_config.h> respectively. * libio/libio.h: Rename the original version of this file to libio/bits/libio.h.

Joseph Myers	67f0aff0c6	Fix sigval namespace (bug 21944). XPG4.2 defines the siginfo_t type, but not union sigval or its contents (which were added in the 1993 edition of POSIX.1), resulting in namespace violations for sigval, sival_int and sival_ptr for signal.h and sys/wait.h for that standard because those headers incorrectly expose those names in that case. This patch fixes this problem. The public type in this case is union sigval, but various places in the headers use the sigval_t name for it; direct uses of union sigval are already properly guarded or in headers not in XPG4.2. Now, sigval_t, although not a standard name, does seem to be widely used outside glibc. The approach taken by this patch is to make installed headers use the name __sigval_t instead. __sigval_t is then defined to either union sigval or union __sigval (where union __sigval has __-prefixed member names as well), depending on whether there are any namespace issues with the union sigval name and its members. In the case where union __sigval is used, sigval_t is not defined at all, to avoid the problem of sigval_t having a C++ mangled name that depends on feature test macros. sigval_t is still defined by signal.h if __USE_MISC (reflecting the nonstandard nature of that name). Tested for x86_64.

Zack Weinberg	f0be25b633	Rename xlocale.h to bits/types/__locale_t.h. xlocale.h is already a single-type micro-header, defining struct __locale_struct and the typedefs __locale_t and locale_t. This patch brings it into the bits/types/ scheme: there are now bits/types/__locale_t.h which defines only __locale_struct and __locale_t, and bits/types/locale_t.h which defines locale_t as well as the other two. None of our headers need __locale_t.h, but it appears to me that libstdc++ could make use of it. There are a lot of external uses of xlocale.h, but all the uses I checked had an autoconf test or equivalent for its existence. It has never been available from other C libraries, and it has always contained a comment reading "This file is not standardized, don't rely on it, it can go away without warning" so I think dropping it is pretty safe. I also took the opportunity to clean up comments in various public header files that still talk about the _l interfaces as though they were completely nonstandard. There are a few of them, notably the strtoX_l and wcstoX_l families, that haven't been standardized, but the bulk are in POSIX.1-2008. locale/xlocale.h: Rename to... * locale/bits/types/__locale_t.h: ...here.

Joseph Myers	a66bc30d6b	Define struct rusage in sys/wait.h when required (bug 21575). Some older standards (XPG4.2 through POSIX.1:2001, XSI only) require sys/wait.h to include the definition of struct rusage. This is missing in glibc. This patch adds the required definition. struct rusage is moved to a new header bits/types/struct_rusage.h to avoid bringing in the whole of sys/resource.h (although the standards in question do allow the whole of sys/resource.h to be brought in). In the five bits/resource.h headers, the only variation between the definitions of struct rusage is that the sysdeps/unix/sysv/linux version is prepared for x32 (by having anonymous unions with __syscall_slong_t fields) and the others are not. Thus, this version is suitable for use generically (everything other than x32 simply has __syscall_slong_t the same as long int, so there are no API or ABI changes involved, and anonymous unions are already a required language feature for glibc headers elsewhere), and this patch uses it as a base for the single implementation of bits/types/struct_rusage.h. Tested for x86_64, and with build-many-glibcs.py.

Zack Weinberg	37f802f864	Remove __need_IOV_MAX and __need_FOPEN_MAX. __need_FOPEN_MAX wasn't being used anywhere. __need_IOV_MAX was more complicated; the basic deal is that sys/uio.h wants to define a constant named UIO_MAXIOV and bits/xopen_lim.h wants to define a constant named IOV_MAX, with the same meaning. For no apparent reason this was being handled via bits/stdio_lim.h -- stdio.h is NOT supposed to define IOV_MAX -- and some mess in Makerules. Also, bits/uio.h on Linux was being used as a dumping ground for extension functions. So now we have bits/uio_lim.h, which defines __IOV_MAX. bits/xopen_lim.h and sys/uio.h use that to define their respective constants. We also now have bits/uio-ext.h, which is the official Proper Home for extensions to sys/uio.h. bits/uio.h is removed, and stdio_lim.h doesn't define IOV_MAX at all. * bits/uio_lim.h, sysdeps/unix/sysv/linux/bits/uio_lim.h * bits/uio-ext.h, sysdeps/unix/sysv/linux/bits/uio-ext.h: New file. * bits/uio.h, sysdeps/unix/sysv/linux/bits/uio.h: Delete file. * include/bits/xopen_lim.h: Use bits/uio_lim.h to get the value for IOV_MAX. * misc/Makefile: Install bits/uio-ext.h and bits/uio_lim.h.

Zack Weinberg	46ee3da55e	Remove __need_schedparam and __cpu_set_t_defined. bits/sched.h has logic to expose only an impl-namespace variant of struct sched_param (i.e. struct __sched_param), but nothing uses it, and the only header that includes bits/sched.h is sched.h. The __need_schedparam logic can therefore be removed. bits/sched.h also has a great deal of code relating to cpu_set_t objects that was almost the same between the two versions of bits/sched.h in the tree; a little spelunking indicated that this is because some bug fixes got applied to the Linux-specific bits/sched.h but not the generic one. Introduce a new header, bits/cpu-set.h, containing the version of that code with the bugfixes, have sched.h include it directly, and delete all of the code from both versions of bits/sched.h. Also remove the unnecessary name mangling in the definition of struct sched_param -- POSIX specifies a field 'sched_priority', so there is no reason to define it as '__sched_priority' and then paper over that with a macro. (Just in case someone was using the internal name, 'sched_priority' remains a macro defined to expand to itself, and '__sched_priority' now expands to 'sched_priority'.) Finally, as long as I'm touching these files anyway, merge new constants from linux/sched.h into the Linux bits/sched.h. * bits/sched.h: Remove __need_schedparam logic and replace with a normal multiple-include guard. Change field name in struct sched_param from __sched_priority to sched_priority. Delete everything under #ifndef __cpu_set_t_defined. * sysdeps/unix/sysv/linux/bits/sched.h: Likewise. Also sync with kernel sched.h, adding SCHED_ISO and SCHED_DEADLINE constants. * posix/sched.h: Include bits/cpu-set.h as well as bits/sched.h. For compatibility, #define sched_priority to itself, and #define __sched_priority as sched_priority. * posix/bits/cpu-set.h: New file containing, verbatim, the code that was under #ifndef __cpu_set_t_defined in sysdeps/unix/sysv/linux/bits/sched.h. * include/bits/cpu-set.h: New wrapper. * posix/Makefile: Install bits/cpu-set.h.	9 years ago
Zack Weinberg	199fc19d3a	Remove __need macros from stdio.h and wchar.h. wint_t is a little finicky because it might be defined by stddef.h, which belongs to the compiler.

Joseph Myers	81df4d253d	Fix include paths in include/bits/types/.h. Various include/bits/types/.h files do where the path specified is relative to the toplevel glibc source directory. That has the wrong number of ../ components to achieve the desired effect; it actually searches relative to include/ for a file that does not exist there, then goes on to search the #include <> paths specified with -I, eventually finding the desired file via such a path (e.g. sysdeps/nptl/) with the right number of directory components. Before that it searches include/../.. because of the -Iinclude, meaning that an appropriately named file outside the glibc source tree can affect the build. This patch changes all those files to do #include <path> without the ../../, as some such files already do.

Zack Weinberg	a992f506ff	Remove __need macros from signal.h. The types affected are __sig_atomic_t, sig_atomic_t, __sigset_t, sigset_t, sigval_t, sigevent_t, and siginfo_t. __sig_atomic_t is a scalar, so it's now directly available from bits/types.h. The others get bits/types/ headers. Side effects include: There have been small changes to which non-signal headers expose which subset of the signal-related types. A couple of architectures' nested siginfo_t fields had to be renamed to prevent undesired macro expansion. Internal code that wants to manipulate signal masks must now include <sigsetops.h> (which is not installed) and should be aware that __sigaddset, __sigandset, __sigdelset, __sigemptyset, and __sigorset no longer return a value (unlike the public API). Relatedly, the public signal.h no longer declares any of those functions. The obsolete sigmask() macro no longer has a system-specific definition -- in the cases where it matters, it didn't work anyway. New Linux architectures should create bits/siginfo-arch.h and/or bits/siginfo-consts-arch.h to customize their siginfo_t, rather than duplicating everything in bits/siginfo.h (which no longer exists). Add new __SI_* macros if necessary.

Zack Weinberg	500b3a499f	Remove __need_list_t and __need_res_state. These __need macros are only used internally, by nptl/descr.h. However, including all of resolv.h from descr.h causes build failures due to resolv.h's dozens of pseudo-struct-field macros, some of which collide with struct fields in NPTL internal data structures. Similarly, including all of list.h from descr.h produces an include cycle, atomic.h -> atomic-machine.h -> tls.h -> descr.h -> list.h -> atomic.h, and then list.h tries to use atomic.h macros that haven't been defined yet.

Joseph Myers	0bcec5321f	Split up bits/sigstack.h. bits/sigstack.h contains four things: the legacy struct sigstack type, the preferred stack_t type, the SS_* enum values and macros for signal stack sizes. These vary in different ways between glibc configurations; in particular, the stack sizes vary much more than any of the other pieces. Furthermore, these pieces have different standard namespace rules for when they should be visible (not currently visible in conform/ results both because the relevant tests are XFAILed for sys/ucontext.h namespace issues, and because some of the expectations are incorrect in the same way as the headers, e.g. neither expectations nor headers reflect that current POSIX no longer has either the sigstack function or the sigstack structure). To reduce duplication of identical definitions, and facilitate namespace fixes without requiring the same feature test macro conditions to be repeated in many versions of the same header, this patch splits bits/sigstack.h up into four headers. It keeps the stack size macros, while new bits/types/struct_sigstack.h, bits/types/stack_t.h and bits/ss_flags.h are added for the other pieces. bits/types/struct_sigstack.h is the same everywhere, bits/types/stack_t.h has three variants different in the order of the structure elements (generic = MIPS Linux, and other Linux), and bits/ss_flags.h has generic and Linux variants. This patch includes the new headers everywhere that included <bits/sigstack.h>, so should cause no difference to what any public header defines.

Joseph Myers	9fe3c80c7c	Fix sys/socket.h namespace issues from sys/uio.h inclusion (bug 21426). sys/socket.h includes sys/uio.h to get the definition of the iovec structure. POSIX allows sys/socket.h to make all sys/uio.h symbols visible. However, all of sys/uio.h is XSI-shaded, so for non-XSI POSIX this results in conformtest failures (for sys/socket.h and other headers that include it): Namespace violation: "UIO_MAXIOV" Namespace violation: "readv" Namespace violation: "writev" Now, there is some ambiguity in POSIX about what namespace reservations apply in this case - see http://austingroupbugs.net/view.php?id=1127 - but glibc convention would still avoid declaring readv and writev, for example, for feature test macros that don't include them (if only headers from the relevant standard are included), even if such declarations are permitted, so there is a bug here according to glibc conventions. This patch moves the struct iovec definition to a new bits/types/struct_iovec.h header and includes that from sys/socket.h instead of including the whole of sys/uio.h. This fixes the namespace issue; however, three files in glibc that were relying on the implicit inclusion needed to be updated to include sys/uio.h explicitly. So there is a question of whether sys/socket.h should continue to include sys/uio.h under some conditions, such as __USE_XOPEN or __USE_MISC or __USE_XOPEN \|\| __USE_MISC, for greater compatibility with code that (wrongly) expects this optional inclusion to be present there. (I think the three affected files in glibc should still have explicit sys/uio.h inclusions added in any case, however.) Tested for x86_64.

Zack Weinberg	10a33cf8b4	getopt: eliminate __need_getopt by splitting up getopt.h. __need_getopt is misnamed; what it really means is "we want only the getopt features specified in POSIX, not the GNU extensions". Because this code is shared with gnulib, it winds up being cleanest to split getopt.h into four headers. getopt_core.h and getopt_ext.h will be shared with gnulib, getopt_posix.h will be just for glibc, and each project will have its own copy of getopt.h. * posix/bits/getopt_core.h, posix/bits/getopt_ext.h: New files, intended to be shared with gnulib. * posix/bits/getopt_posix.h: New file, not intended to be shared with gnulib. * posix/getopt.h: Now just includes features.h, bits/getopt_core.h, and bits/getopt_ext.h.

Gabriel F. T. Gomes	ff80ec4283	Split helper classification macros from mathcalls.h The classification macros: finite, fpclassify, iseqsig, isinf, isnan, issignaling, and signbit are defined by ISO C11 and declared in mathcalls.h for each of the floating-point types: float, double, and long double. TS 18661-3 does not mention these macros for float128, however support for them must be present when _Float128 is present. This is true, even when the feature test macro __STDC_WANT_IEC_60559_TYPES_EXT__ is false. Other function declarations in mathcalls.h, on the other hand, depend on __STDC_WANT_IEC_60559_TYPES_EXT__. This patch splits the helper functions (__finite, __fpclassify, __iseqsig, __isinf, __isnan, __issignaling, and __signbit) from mathcalls.h, so that these helper functions can be declared for _Float128, even when __STDC_WANT_IEC_60559_TYPES_EXT__ is false. Tested for powerpc64le, s390x, and x86_64. * include/bits/mathcalls-helper-functions.h: New file. * math/Makefile (headers): Add bits/mathcalls-helper-functions.h. * math/bits/mathcalls.h (__finite, __fpclassify, __iseqsig) (__isinf, __isnan, __issignaling, __signbit): Move declarations to math/bits/mathcalls-helper-functions.h. * math/bits/mathcalls-helper-functions.h: New file. * math/math.h: Include bits/mathcalls-helper-functions.h for float, double, and long double.	9 years ago

Adhemerval Zanella	38765ab68f	Use fortify macros for b{zero,copy} along decl from strings.h As described in BZ#20558, bzero and bcopy declaration can only benefit from fortified macros when decl came from string.h and when __USE_MISC is defined (default behaviour). This is due no standard includes those functions in string.h, so they are only declared if __USE_MISC is defined (as pointed out in comment 4). However fortification should be orthogona to other features test macros, i.e, any function should be fortified if that function is declared. To fix this behavior, the patch moved the bzero, bcopy, and __explicit_bzero_chk to a common header (string/bits/strings_fortified.h) and explicit fortified inclusion macros similar to string.h is added on strings.h. This allows to get fortified declarions by only including strings.h. Checked on x86_64-linux-gnu and along on a bootstrap installation to check if the fortified are correctly triggered with example from bug report. [BZ #20558] * string/bits/string3.h [__USE_MISC] (bcopy): Move to strings_fortified.h. [__USE_MISC] (bzero): Likewise.

Zack Weinberg	05b68e14b1	Installed-header hygiene (BZ#20366): time.h types. Many headers are expected to expose a subset of the type definitions in time.h. time.h has a whole bunch of messy logic for conditionally defining some its types and structs, but, as best I can tell, this has never worked 100%. In particular, __need_timespec is ineffective if _TIME_H has already been defined, which means that if you compile #include <time.h> #include <sched.h> with e.g. -fsyntax-only -std=c89 -Wall -Wsystem-headers, you will get In file included from test.c:2:0: /usr/include/sched.h:74:57: warning: "struct timespec" declared inside parameter list will not be visible outside of this definition or declaration extern int sched_rr_get_interval (__pid_t __pid, struct timespec __t) __THROW; ^~~~~~~~ And if you want to _use_ sched_rr_get_interval in a TU compiled that way, you're hosed. This patch replaces all of that with small bits/types/TYPE.h headers as introduced earlier. time.h and bits/time.h are now much* simpler, and a lot of other headers are slightly simpler. * time/time.h, bits/time.h, sysdeps/unix/sysv/linux/bits/time.h: Remove all logic conditional on __need macros. Move all the conditionally defined types to their own headers... * time/bits/types/clock_t.h: Define clock_t here. * time/bits/types/clockid_t.h: Define clockid_t here. * time/bits/types/struct_itimerspec.h: Define struct itimerspec here. * time/bits/types/struct_timespec.h: Define struct timespec here. * time/bits/types/struct_timeval.h: Define struct timeval here. * time/bits/types/struct_tm.h: Define struct tm here. * time/bits/types/time_t.h: Define time_t here. * time/bits/types/timer_t.h: Define timer_t here. * time/Makefile: Install the new headers. * bits/resource.h, io/fcntl.h, io/sys/poll.h, io/sys/stat.h * io/utime.h, misc/sys/select.h, posix/sched.h, posix/sys/times.h * posix/sys/types.h, resolv/netdb.h, rt/aio.h, rt/mqueue.h * signal/signal.h, pthread/semaphore.h, sysdeps/nptl/pthread.h * sysdeps/unix/sysv/linux/alpha/bits/resource.h * sysdeps/unix/sysv/linux/alpha/sys/acct.h * sysdeps/unix/sysv/linux/bits/resource.h * sysdeps/unix/sysv/linux/bits/timex.h * sysdeps/unix/sysv/linux/mips/bits/resource.h * sysdeps/unix/sysv/linux/net/ppp_defs.h * sysdeps/unix/sysv/linux/sparc/bits/resource.h * sysdeps/unix/sysv/linux/sys/acct.h * sysdeps/unix/sysv/linux/sys/timerfd.h * sysvipc/sys/msg.h, sysvipc/sys/sem.h, sysvipc/sys/shm.h * time/sys/time.h, time/sys/timeb.h Use the new bits/types headers. * include/time.h: Remove __need logic. * include/bits/time.h * include/bits/types/clock_t.h, include/bits/types/clockid_t.h * include/bits/types/time_t.h, include/bits/types/timer_t.h * include/bits/types/struct_itimerspec.h * include/bits/types/struct_timespec.h * include/bits/types/struct_timeval.h * include/bits/types/struct_tm.h: New wrapper headers.	10 years ago
Zack Weinberg	f2bea4da2e	Installed-header hygiene (BZ#20366): conditionally defined structures. Several network-related structures are defined conditionally under __USE_MISC, but unconditionally used by other headers. The path of least resistance is usually to condition the uses on __USE_MISC as well. * sysdeps/mach/hurd/net/if_ppp.h * sysdeps/unix/sysv/linux/net/if_ppp.h: Only define struct ifpppstatsreq and struct ifpppcstatsreq if __USE_MISC is defined, to ensure struct ifreq is declared. * inet/netinet/ether.h: Condition all function prototypes on __USE_MISC, to ensure struct ether_addr is declared. sys/socket.h defines struct osockaddr only under __USE_MISC, whereas protocols/talkd.h requires it unconditionally. Here it doesn't make sense to condition the entire body of protocols/talkd.h on __USE_MISC. Rather than complicate sys/socket.h with a __need macro or duplicate the definition, I am introducing a new concept: tiny headers named bits/types/TYPE.h that define TYPE and nothing else. This can, I hope, ultimately replace all the __need macros. The guard macro for such headers will be __TYPE_defined, just in case application or third-party library code is looking at them. * socket/bits/types/struct_osockaddr.h: New header. * include/bits/types/struct_osockaddr.h: New wrapper. * socket/Makefile: Install the new header. * socket/sys/socket.h, inet/protocols/talkd.h: Refer to bits/types/struct_osockaddr.h for the definition of struct osockaddr.	10 years ago
Joseph Myers	eb64b6d457	Fix limits.h NL_NMAX namespace (bug 19929). bits/xopen_lim.h (included by limits.h if __USE_XOPEN) defines NL_NMAX, but this constant was removed in the 2008 edition of POSIX so should not be defined in that case. This patch duly disables that define for __USE_XOPEN2K8. It remains enabled for __USE_GNU to avoid affecting sysconf (_SC_NL_NMAX), the implementation of which uses "#ifdef NL_NMAX". Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch).

Ten conformtest failures arise from the internal header include/bits/ipc.h failing to condition internal declarations, outside the public namespace of headers including bits/ipc.h, on [!_ISOMAC]. As discussed in <https://sourceware.org/ml/libc-alpha/2015-06/msg00653.html>, the internal declarations that are actually relevant are in ipc_priv.h and so include/bits/ipc.h should not be needed at all; this patch removes it. (Ten further conformtest failures for other headers including bits/ipc.h remain because of other conformance issues in those headers.)
