2024-02-01Refer to C23 in place of C2X in glibcJoseph Myers1-1/+1
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.

I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah.

2019-08-13Declare most TS 18661-1 interfaces for C2X.Joseph Myers1-1/+1
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).

2018-03-20Remove powerpc, sparc fdim inlines (bug 22987).Joseph Myers1-57/+0
The powerpc and sparc bits/mathinline.h include inlines of fdim and fdimf. These are not restricted to -fno-math-errno, but do not set errno, and wrongly use ordered <= comparisons instead of the required islessequal comparisons (this latter issue is latent on powerpc because GCC wrongly uses unordered comparison instructions for operations that should use ordered comparison instructions). Since we wish to avoid such header inlines anyway, leaving it to the compiler to inline such standard functions under appropriate conditions, this patch fixes those issues by removing the inlines in question (and thus removing the sparc bits/mathinline.h header which had no other inlines left in it). I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85003> for adding correct fdim inlines to GCC, since the function is simple enough that a correct inline is a perfectly reasonable architecture-independent optimization with -fno-math-errno and in the absence of implicit excess precision. Tested with build-many-glibcs.py for all its powerpc and sparc configurations. [BZ #22987] * sysdeps/powerpc/bits/mathinline.h (fdim): Remove inline function. (fdimf): Likewise. * sysdeps/sparc/fpu/bits/mathinline.h: Remove file.
2018-03-15Remove all target specific __ieee754_sqrt(f/l) inlinesWilco Dijkstra1-80/+0
Remove the now unused target specific__ieee754_sqrt(f/l) inlines. Also remove inlines of sqrt which are for really old GCC versions. Removing these is desirable, under the general principle of leaving such inlining to the compiler rather than trying to do it in installed headers, especially when only very old compilers are affected. Note that removing inlines for __ieee754_sqrt disables inlining in the sqrt wrapper functions. Given the sqrt function will typically only be called for negative arguments, it doesn't matter whether the inlining happens or not. * sysdeps/aarch64/fpu/math_private.h (__ieee754_sqrt): Remove.

2017-09-28Simplify C99 isgreater macrosWilco Dijkstra1-99/+0
Simplify the C99 isgreater macros. Although some support was added in GCC 2.97, not all targets added support until GCC 3.1. Therefore only use the builtins in math.h from GCC 3.1 onwards, and defer to generic macros otherwise. Improve the generic isunordered macro to use compares rather than call fpclassify twice - this is not only faster but also correct for signaling NaNs. * math/math.h: Improve handling of C99 isgreater macros. * sysdeps/alpha/fpu/bits/mathinline.h: Remove isgreater macros. * sysdeps/m68k/m680x0/fpu/bits/mathinline.h: Likewise. * sysdeps/powerpc/bits/mathinline.h: Likewise. * sysdeps/sparc/fpu/bits/mathinline.h: Likewise. * sysdeps/x86/fpu/bits/mathinline.h: Likewise.

2016-09-07Add femode_t functions.Joseph Myers1-0/+8
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).
