2024-02-01Refer to C23 in place of C2X in glibcJoseph Myers
WG14 decided to use the name C23 as the informal name of the next revision of the C standard (notwithstanding the publication date in 2024). Update references to C2X in glibc to use the C23 name. This is intended to update everything *except* where it involves renaming files (the changes involving renaming tests are intended to be done separately). In the case of the _ISOC2X_SOURCE feature test macro - the only user-visible interface involved - support for that macro is kept for backwards compatibility, while adding _ISOC23_SOURCE. Tested for x86_64.

2019-10-01Split up endian.h to minimize exposure of BYTE_ORDER.Alistair Francis
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.

2019-08-13Declare most TS 18661-1 interfaces for C2X.Joseph Myers
C2X adds the interfaces from TS 18661-1, and all except a handful in Annex F are unconditionally visible in C2X rather than only visible when __STDC_WANT_IEC_60559_BFP_EXT__ is defined. This patch updates glibc headers accordingly: most uses of __GLIBC_USE (IEC_60559_BFP_EXT) are changed to a new __GLIBC_USE (IEC_60559_BFP_EXT_C2X).

2018-08-02Do not define various fenv.h macros for MIPS soft-float (bug 23479).Joseph Myers
MIPS soft-float glibc does not support floating-point exceptions and rounding modes, and uses a different ABI from hard-float so a soft-float compilation cannot use a glibc that does support floating-point exceptions and rounding modes. Thus, bits/fenv.h should not, when compiling for soft-float, define macros for the unsupported features. This patch changes it accordingly to define those macros only for hard-float. None of the exception macros are defined for soft-float, with FE_ALL_EXCEPT defined to 0 in that case, and only FE_TONEAREST is defined of the rounding-mode macros, and FE_NOMASK_ENV is not defined; this is consistent with how architectures lacking exception and rounding mode support generally define things in this header. As well as making the header more correct for this case, this also means the generic math_private.h optimizations for this case automatically apply (inlining libm-internal fenv.h function calls that are trivial when exceptions and rounding modes are not supported). The mips64 sfp-machine.h then needs similar changes to disable more of the exception and rounding mode handling for soft-float. (The mips32 sfp-machine.h is already used only for soft-float, has no integration with hardware exceptions or rounding modes and so needs no changes.) Existing binaries might use the old FE_NOMASK_ENV value as an argument to fesetenv / feupdateenv and expect an error for it (given that it was defined in a header that also defined FE_ALL_EXCEPT to a nonzero value). To preserve that error, wrappers for the fallback fesetenv and feupdateenv are created in sysdeps/mips/nofpu/. Tested for mips64 (hard-float and soft-float, all three ABIs).

2017-10-19Install correct bits/long-double.h for MIPS64 (bug 22322).Joseph Myers
Similar to bug 21987 for SPARC, MIPS64 wrongly installs the ldbl-128 version of bits/long-double.h, meaning incorrect results when using headers installed from a 64-bit installation for a 32-bit build. (I haven't actually seen this cause build failures before its interaction with bits/floatn.h did so - installed headers wrongly expecting _Float128 to be available in a 32-bit configuration.) This patch fixes the bug by moving the MIPS header to sysdeps/mips/ieee754, which comes before sysdeps/ieee754/ldbl-128 in the sysdeps directory ordering. (bits/floatn.h will need a similar fix - duplicating the ldbl-128 version for MIPS will suffice - for headers from a 32-bit installation to be correct for 64-bit builds.) Tested with build-many-glibcs.py (compilers build for mips64-linux-gnu, where there was previously a libstdc++ build failure as at <https://sourceware.org/ml/libc-testresults/2017-q4/msg00130.html>).

2017-08-31Simplify NAN definitions.Joseph Myers
Similar to my patches for HUGE_VAL and INFINITY. this patch eliminates the bits/nan.h headers. __builtin_nanf ("") is used to define NAN for GCC 3.3 and later; the fallback is (0.0f / 0.0f), which is a constant expression for a quiet NaN of type float, but raises a spurious "invalid" exception outside static initializers, which seems the best that can be done purely in standard C. Again, if anyone actually uses a compiler with its own incompatible extension for producing a constant quiet NaN, we can add compiler conditionals. Tested for x86_64. * math/math.h [__USE_ISOC99] (NAN): Define directly here. Do not include <bits/nan.h>. * math/Makefile (headers): Remove bits/nan.h. * bits/nan.h: Remove. * sysdeps/ieee754/bits/nan.h: Likewise. * sysdeps/mips/bits/nan.h: Likewise.
2017-08-08Do not use __ptr_t.Joseph Myers
sys/cdefs.h has a macro __ptr_t, which a few places in glibc use instead of void *. void * is a well-understood standard type for that purpose and in a post-C89 context there is no need for a macro for it; this patch changes those places to use void * directly instead. Unlike __long_double_t, __ptr_t is widely used outside glibc (or at least has many hits on codesearch.debian.net). I don't know how many of those uses would break if sys/cdefs.h ceased to define the macro, but there's enough risk that this patch leaves the definition and just removes the uses within glibc; removal of the definition can be considered separately if desired.

2016-12-14Refactor long double information into bits/long-double.h.Joseph Myers
Information about whether the ABI of long double is the same as that of double is split between bits/mathdef.h and bits/wordsize.h. When the ABIs are the same, bits/mathdef.h defines __NO_LONG_DOUBLE_MATH. In addition, in the case where the same glibc binary supports both -mlong-double-64 and -mlong-double-128, bits/wordsize.h defines __LONG_DOUBLE_MATH_OPTIONAL, along with __NO_LONG_DOUBLE_MATH if this particular compilation is with -mlong-double-64. As part of the refactoring I proposed in <https://sourceware.org/ml/libc-alpha/2016-11/msg00745.html>, this patch puts all that information in a single header, bits/long-double.h. It is included from sys/cdefs.h alongside the include of bits/wordsize.h, so other headers generally do not need to include bits/long-double.h directly. Previously, various bits/mathdef.h headers and bits/wordsize.h headers had this long double information (including implicitly in some bits/mathdef.h headers through not having the defines present in the default version). After the patch, it's all in six bits/long-double.h headers. Furthermore, most of those new headers are not architecture-specific. Architectures with optional long double all use the ldbl-opt sysdeps directory, either in the order (ldbl-64-128, ldbl-opt, ldbl-128) or (ldbl-128ibm, ldbl-opt). Thus a generic header for the case where long double = double, and headers in ldbl-128, ldbl-96 and ldbl-opt, suffices to cover every architecture except for cases where long double properties vary between different ABIs sharing a set of installed headers; fortunately all the ldbl-opt cases share a single compiler-predefined macro __LONG_DOUBLE_128__ that can be used to tell whether this compilation is -mlong-double-64 or -mlong-double-128. The two cases where a set of headers is shared between ABIs with different long double properties, MIPS (o32 has long double = double, other ABIs use ldbl-128) and SPARC (32-bit has optional long double, 64-bit has required long double), need their own bits/long-double.h headers. As with bits/wordsize.h, multiple-include protection for this header is generally implicit through the include guards on sys/cdefs.h, and multiple inclusion is harmless in any case. There is one subtlety: the header must not define __LONG_DOUBLE_MATH_OPTIONAL if __NO_LONG_DOUBLE_MATH was defined before its inclusion, because doing so breaks how sysdeps/ieee754/ldbl-opt/nldbl-compat.h defines __NO_LONG_DOUBLE_MATH itself before including system headers. Subject to keeping that working, it would be reasonable to move these macros from defined/undefined #ifdef to always-defined 1/0 #if semantics, but this patch does not attempt to do so, just rearranges where the macros are defined. After this patch, the only use of bits/mathdef.h is the alpha one for modifying complex function ABIs for old GCC.

2016-12-01Refactor FP_ILOGB* out of bits/mathdef.h.Joseph Myers
Continuing the refactoring of bits/mathdef.h, this patch stops it defining FP_ILOGB0 and FP_ILOGBNAN, moving the required information to a new header bits/fp-logb.h. There are only two possible values of each of those macros permitted by ISO C. TS 18661-1 adds corresponding macros for llogb, and their values are required to correspond to those of the ilogb macros in the obvious way. Thus two boolean values - for which the same choices are correct for most architectures - suffice to determine the value of all these macros, and by defining macros for those boolean values in bits/fp-logb.h we can then define the public FP_* macros in math.h and avoid the present duplication of the associated feature test macro logic. This patch duly moves to bits/fp-logb.h defining __FP_LOGB0_IS_MIN and __FP_LOGBNAN_IS_MIN. Default definitions of those to 0 are correct for both architectures, while ia64, m68k and x86 get their own versions of bits/fp-logb.h to reflect their use of values different from the defaults. The patch renders many copies of bits/mathdef.h trivial (needed only to avoid the default __NO_LONG_DOUBLE_MATH). I'll revise <https://sourceware.org/ml/libc-alpha/2016-11/msg00865.html> accordingly so that it removes all bits/mathdef.h headers except the default one and the alpha one, and arranges for the header to be included only by complex.h as the only remaining use at that point will be for the alpha ABI issues there. Tested for x86_64 and x86. Also did compile-only testing with build-many-glibcs.py (using glibc sources from before the commit that introduced many build failures with undefined __GI___sigsetjmp). * bits/fp-logb.h: New file. * sysdeps/ia64/bits/fp-logb.h: Likewise. * sysdeps/m68k/m680x0/bits/fp-logb.h: Likewise. * sysdeps/x86/bits/fp-logb.h: Likewise. * math/Makefile (headers): Add bits/fp-logb.h. * math/math.h: Include <bits/fp-logb.h>.

2016-11-24Refactor float_t, double_t information into bits/flt-eval-method.h.Joseph Myers
At present, definitions of float_t and double_t are split among many bits/mathdef.h headers. For all but three architectures, these types are float and double. Furthermore, if you assume __FLT_EVAL_METHOD__ to be defined, that provides a more generic way of determining the correct values of these typedefs. Defining these typedefs more generally based on __FLT_EVAL_METHOD__ was previously proposed by Paul Eggert in <https://sourceware.org/ml/libc-alpha/2012-02/msg00002.html>. This patch refactors things in the way I proposed in <https://sourceware.org/ml/libc-alpha/2016-11/msg00745.html>. A new header bits/flt-eval-method.h defines a single macro, __GLIBC_FLT_EVAL_METHOD, which is then used by math.h to define float_t and double_t. The default is based on __FLT_EVAL_METHOD__ (although actually a default to 0 would have the same effect for current ports, because ports where values other than 0 or 16 are possible all have their own headers). To avoid changing the existing semantics in any case, including for compilers not defining __FLT_EVAL_METHOD__, architecture-specific files are then added for m68k, s390, x86 which replicate the existing semantics. At least with __FLT_EVAL_METHOD__ values possible with GCC, there should be no change to the choices of float_t and double_t for any supported configuration. Architecture maintainer notes: * m68k: sysdeps/m68k/m680x0/bits/flt-eval-method.h always defines __GLIBC_FLT_EVAL_METHOD to 2 to replicate the existing logic. But actually GCC defines __FLT_EVAL_METHOD__ to 0 if TARGET_68040. It might make sense to make the header prefer to base things on __FLT_EVAL_METHOD__ if defined, like the x86 version, and so make the choices of these types more accurate (with a NEWS entry as for the other changes to these types on particular architectures). * s390: sysdeps/s390/bits/flt-eval-method.h always defines __GLIBC_FLT_EVAL_METHOD to 1 to replicate the existing logic. As previously discussed, it might make sense in coordination with GCC to eliminate the historic mistake, avoid excess precision in the -fexcess-precision=standard case and make the typedefs match (with a NEWS entry, again). Tested for x86-64 and x86.

2016-09-07Add femode_t functions.Joseph Myers
TS 18661-1 defines a type femode_t to represent the set of dynamic floating-point control modes (such as the rounding mode and trap enablement modes), and functions fegetmode and fesetmode to manipulate those modes (without affecting other state such as the raised exception flags) and a corresponding macro FE_DFL_MODE. This patch series implements those interfaces for glibc. This first patch adds the architecture-independent pieces, the x86 and x86_64 implementations, and the <bits/fenv.h> and ABI baseline updates for all architectures so glibc keeps building and passing the ABI tests on all architectures. Subsequent patches add the fegetmode and fesetmode implementations for other architectures. femode_t is generally an integer type - the same type as fenv_t, or as the single element of fenv_t where fenv_t is a structure containing a single integer (or the single relevant element, where it has elements for both status and control registers) - except where architecture properties or consistency with the fenv_t implementation indicate otherwise. FE_DFL_MODE follows FE_DFL_ENV in whether it's a magic pointer value (-1 cast to const femode_t *), a value that can be distinguished from valid pointers by its high bits but otherwise contains a representation of the desired register contents, or a pointer to a constant variable (the powerpc case; __fe_dfl_mode is added as an exported constant object, an alias to __fe_dfl_env). Note that where architectures (that share a register between control and status bits) gain definitions of new floating-point control or status bits in future, the implementations of fesetmode for those architectures may need updating (depending on whether the new bits are control or status bits and what the implementation does with previously unknown bits), just like existing implementations of <fenv.h> functions that take care not to touch reserved bits may need updating when the set of reserved bits changes. (As any new bits are outside the scope of ISO C, that's just a quality-of-implementation issue for supporting them, not a conformance issue.) As with fenv_t, femode_t should properly include any software DFP rounding mode (and for both fenv_t and femode_t I'd consider that fragment of DFP support appropriate for inclusion in glibc even in the absence of the rest of libdfp; hardware DFP rounding modes should already be included if the definitions of which bits are status / control bits are correct). Tested for x86_64, x86, mips64 (hard float, and soft float to test the fallback version), arm (hard float) and powerpc (hard float, soft float and e500).

2015-09-11Move bits/atomic.h to atomic-machine.h (bug 14912).Joseph Myers
It was noted in <https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the bits/*.h naming scheme should only be used for installed headers.

This is the only change in this series that needs to change the filename rather than simply removing a directory level (because both atomic.h and bits/atomic.h exist at present).

2015-09-08MIPS: Only use .set mips* assembler directives when necessaryAndrew Bennett
There are a few .set mips* assembler directives used in the MIPS specific sysdep code that force an instruction to be assembled for a specific ISA. The reason for these is to allow an instruction to be encoded when it might not be supported in the current ISA (when the code is run the Linux kernel will trap and emulate any unsupported instructions). Unfortunately forcing a specific ISA means that when assembling for a newer ISA, where the instruction has a different encoding, the wrong encoding will be used. * sysdeps/mips/bits/atomic.h [_MIPS_SIM == _ABIO32] (MIPS_PUSH_MIPS2): Only use .set mips2 if the current ISA is below mips2. * sysdeps/mips/sys/tas.h [_MIPS_SIM == _ABIO32] (_test_and_set): Likewise. * sysdeps/mips/nptl/tls.h (READ_THREAD_POINTER): Only use .set mips32r2 if the current ISA is below mips32r2. * sysdeps/mips/tls-macros.h (TLS_RDHWR): New define.

2015-09-04Rename bits/linkmap.h to linkmap.h (bug 14912).Joseph Myers
It was noted in <https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the bits/*.h naming scheme should only be used for installed headers. This patch renames bits/linkmap.h to plain linkmap.h to follow that convention. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch).

2015-01-28Disable 64-bit atomics for MIPS n32.Joseph Myers
This patch disables use of 64-bit atomics for MIPS n32 to fix the problems with unaligned semaphores. Before 64-bit atomics are used for anything for which such alignment issues do not arise, and before the addition of any new ILP32 ports with 64-bit semaphores for which the ABI can be set to have the greater alignment (AARCH64?), a better approach will need to be established that allows architectures to declare their 64-bit atomics availability accurately, without doing so causing inappropriate use of such atomics on unaligned semaphores. Tested for MIPS n32 that this fixes the nptl/tst-sem3 failure. * sysdeps/mips/bits/atomic.h [_MIPS_SIM == _ABIN32] (__HAVE_64B_ATOMICS): Define to 0.

2014-11-20Add arch-specific configuration for C11 atomics support.Torvald Riegel
This sets __HAVE_64B_ATOMICS if provided. It also sets USE_ATOMIC_COMPILER_BUILTINS to true if the existing atomic ops use the __atomic* builtins (aarch64, mips partially) or if this has been tested (x86_64); otherwise, this is set to false so that C11 atomics will be based on the existing atomic operations.
2014-03-21Fix -Wundef warnings for _ABI* on MIPS.Joseph Myers
This patch fixes -Wundef warnings related to the _ABI* macros on MIPS. GCC predefines only the _ABI* macro related to the ABI actually in use, meaning that a conditional such as "#if _MIPS_SIM == _ABI64" is true only for the ABI in question (all the macros are nonzero), but produces a -Wundef warning for the other ABIs. The normal approach to using these macros is to include <sgidefs.h>, which ensures that all three _ABI* macros are defined rather than just one; this patch does so in the places that caused warnings (the bulk of the warnings arising from <bits/wordsize.h>). Tested that the warnings are fixed. * sysdeps/mips/bits/wordsize.h: Include <sgidefs.h>. * sysdeps/unix/sysv/linux/mips/getrlimit64.c: Likewise. * sysdeps/unix/sysv/linux/mips/setrlimit64.c: Likewise.
2014-02-10Move mips from ports to libc.Joseph Myers
I've moved the MIPS port from ports to the main sysdeps hierarchy. Beyond the README update, the move of the files was simply git mv ports/sysdeps/mips sysdeps/mips git mv ports/sysdeps/unix/mips sysdeps/unix/mips git mv ports/sysdeps/unix/sysv/linux/mips sysdeps/unix/sysv/linux/mips and in addition to the ChangeLog entries here, I put a note at the top of ports/ChangeLog.mips similar to those in other files. Tested that disassembly of installed shared libraries for mips is the same before and after this patch (except for ld.so where paths in assertions are involved, as for arm). * sysdeps/mips: Move directory from ports/sysdeps/mips. * sysdeps/unix/mips: Move directory from ports/sysdeps/unix/mips. * sysdeps/unix/sysv/linux/mips: Move directory from ports/sysdeps/unix/sysv/linux/mips. * README: Update listing for mips-*-linux-gnu and mips64-*-linux-gnu. * sysdeps/mips: Move directory to ../sysdeps/mips. * sysdeps/unix/mips: Move directory to ../sysdeps/unix/mips. * sysdeps/unix/sysv/linux/mips: Move directory to ../sysdeps/unix/sysv/linux/mips.
