2016-08-29Add fetestexceptflag.Joseph Myers
TS 18661-1 defines an fetestexceptflag function to test the exception state saved in an fexcept_t object by fegetexceptflag. This patch implements this function for glibc. Almost all architectures save exception state in such a way that it can be directly ANDed with exception flag bits, so rather than having lots of fetestexceptflag implementations that all do the same thing, the math/ implementation is made to use this generic logic (which is also OK in the fallback case where FE_ALL_EXCEPT is zero). The only architecture that seems to need anything different is s390. (fegetexceptflag and fesetexceptflag use abbreviated filenames fgetexcptflg.c and fsetexcptflg.c. Because we are no longer concerned by 14-character filename limits, fetestexceptflag uses the obvious filename fetestexceptflag.c.) The NEWS entry is intended to be expanded along the lines given in <https://sourceware.org/ml/libc-alpha/2016-08/msg00356.html> when fegetmode and fesetmode are added. Tested for x86_64, x86, mips64 and powerpc. * math/fetestexceptflag.c: New file. * sysdeps/s390/fpu/fetestexceptflag.c: Likewise.

2016-08-16Add fesetexcept.Joseph Myers
TS 18661-1 defines an fesetexcept function for setting floating-point exception flags without the side-effect of causing enabled traps to be taken. This patch series implements this function for glibc. The present patch adds the fallback stub implementation, x86 and x86_64 implementations, documentation, tests and ABI baseline updates. The remaining patches, some of them untested, add implementations for other architectures. The implementations generally follow those of the fesetexceptflag function. As for fesetexceptflag, the approach taken for architectures where setting flags causes enabled traps to be taken is to set the flags (and potentially cause traps) rather than refusing to set the flags and returning an error. Since ISO C and TS 18661 provide no way to enable traps, this is formally in accordance with the standards. The NEWS entry should be considered a placeholder, since this patch series is intended to be followed by further such series adding other TS 18661-1 features, so that the NEWS entry would end up looking more like * New <fenv.h> features from TS 18661-1:2014 are added to libm: the fesetexcept, fetestexceptflag, fegetmode and fesetmode functions, the femode_t type and the FE_DFL_MODE macro. with hopefully more such entries for other features, rather than having an entry for a single function in the end. I believe we have consensus for adding TS 18661-1 interfaces as per <https://sourceware.org/ml/libc-alpha/2016-06/msg00421.html>.

2016-08-03Support __STDC_WANT_IEC_60559_BFP_EXT__ feature test macro.Joseph Myers
This patch implements support for the __STDC_WANT_IEC_60559_BFP_EXT__ feature test macro from ISO/IEC 18661-1:2014, following the __GLIBC_USE approach now used for __STDC_WANT_LIB_EXT2__. For this macro, the relevant consideration is whether it is defined or undefined when an affected header is included (not what its value is if defined, and not whether it's defined or undefined when any other unaffected system header is included). Currently this macro only affects the issignaling macro and the nextup and nextdown functions (so they can be enabled by defining this macro, not just by defining _GNU_SOURCE as previously). Any further features from this TS added in future would also be conditioned on this macro. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * bits/libc-header-start.h (__GLIBC_USE_IEC_60559_BFP_EXT): New macro. * include/features.h (__STDC_WANT_IEC_60559_BFP_EXT__): Document. * manual/arith.texi (issignaling): Document as ISO from TS 18661-1:2014. (nextup): Likewise. (nextupf): Likewise. (nextupl): Likewise. (nextdown): Likewise. (nextdownf): Likewise.

2016-06-16Add nextup and nextdown math functionsRajalakshmi Srinivasaraghavan
TS 18661 adds nextup and nextdown functions alongside nextafter to provide support for float128 equivalent to it. This patch adds nextupl, nextup, nextupf, nextdownl, nextdown and nextdownf to libm before float128 support. The nextup functions return the next representable value in the direction of positive infinity and the nextdown functions return the next representable value in the direction of negative infinity. These are currently enabled as GNU extensions.
