* Move __fentry__ version definition to sysdeps/{i386,x86_64}Ilya Leoshkevich2018-08-101-3/+0
| | | | | | | | | | | | | | __fentry__ symbol is currently not defined for other architectures. Attempts to introduce it cause abicheck to fail, because it will be available since 2.29 earliest, and not 2.13, which is the case for Intel. With the new code, abicheck passes for i686-linux-gnu, x86_64-linux-gnu and x86_64-linux-gnu32 triples. ChangeLog: * stdlib/Versions: Remove __fentry__. * sysdeps/i386/Versions: Add __fentry__. * sysdeps/x86_64/Versions: Add __fentry__.
* Add _Float32 function aliases.Joseph Myers2017-12-071-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch concludes filling out TS 18661-3 support for different types by adding *f32 function aliases of float functions to support _Float32. As with _Float64 and _Float32x, this is supported for all glibc configurations. As with the previous such patches there are some x86 ulps updates because of inline functions present for float but not for _Float32. The patch also has the usual bits/floatn-common.h update, symbol versions, ABI baselines updates, test enablement and documentation. Tested for x86_64 and x86, and with build-many-glibcs.py, with both GCC 6 and GCC 7. * bits/floatn-common.h (__HAVE_FLOAT32): Define to 1. * manual/math.texi (Mathematics): Document support for _Float32. * math/Makefile (test-types): Add float32. * math/Versions (GLIBC_2.27): Add _Float32 functions. * stdlib/Versions (GLIBC_2.27): Likewise. * wcsmbs/Versions (GLIBC_2.27): Likewise. * sysdeps/unix/sysv/linux/aarch64/libc.abilist: Update. * sysdeps/unix/sysv/linux/aarch64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/alpha/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/alpha/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/arm/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/arm/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/hppa/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/hppa/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/i386/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/i386/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/ia64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/ia64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/m680x0/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/m680x0/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/microblaze/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/microblaze/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/fpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/nofpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/nios2/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/nios2/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc-le.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm-le.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/sh/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/sh/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/libm.abilist: Likewise. * sysdeps/i386/fpu/libm-test-ulps: Likewise. * sysdeps/i386/i686/fpu/multiarch/libm-test-ulps: Likewise.

These types are supported for all glibc configurations. The API corresponds exactly to that for _Float128 and _Float64x. _Float32 aliases to float functions remain to be added in subsequent patches to complete this process (then there are a few miscellaneous functions in TS 18661-3 to implement that aren't simply versions of existing functions for new types). The patch enables the feature in bits/floatn-common.h, adds symbol versions and documentation with updates to ABI baselines, and arranges for the libm functions for the new types to be tested. As with the _Float64x changes there are some x86 ulps updates because of header inlines not used for the new types (and one other change to the non-multiarch libm-test-ulps, which I suppose comes from using a different compiler version / configuration from when it was last regenerated).

(It so happens the set of such platforms is exactly the same as the set of platforms with _Float128 support, although on x86_64, x86 and ia32 the _Float64x format is Intel extended rather than binary128.) The API provided corresponds exactly to that provided for _Float128, mostly coming from TS 18661-3. As these functions always alias those for another type (long double, _Float128 or both), __* function names are not provided, as in other cases of alias types. Given the preparation done in previous patches, this one just enables the feature via Makeconfig and bits/floatn.h, adds symbol versions, and updates documentation and ABI baselines. The symbol versions are present unconditionally as GLIBC_2.27 in the relevant Versions files, as it's OK for those to specify versions for functions that may not be present in some configurations; no additional complexity is needed unless in future some configuration gains support for this type that didn't have such support in 2.27. The Makeconfig additions for ia64 and x86 aren't strictly needed, as those configurations also get float64x-alias-fcts definitions from sysdeps/ieee754/float128/Makeconfig, but still seem appropriate given that _Float64x is not _Float128 for those configurations. A libm-test-ulps update for x86 is included. This is because bits/mathinline.h does not have _Float64x support added and for two functions the use of out-of-line functions results in increased ulps (ifloat64x shares ulps with ildouble / ifloat128 as appropriate). Given that we'd like generally to eliminate bits/mathinline.h optimizations, preferring to have such optimizations in GCC instead, it seems reasonable not to add such support there for new types. GCC support for _FloatN / _FloatNx built-in functions is limited, but has been improved in GCC 8, and at some point I hope the full set of libm built-in functions in GCC, and other optimizations with per-floating-type aspects, will be enabled for all _FloatN / _FloatNx types.

* Move wcstof128 symbol versions to wcsmbs/Versions.Joseph Myers2017-11-241-2/+0
| | | | | | | | | | | | | | This patch moves wcstof128 and wcstof128_l Versions file entries from stdlib/Versions to wcsmbs/Versions, which is a more appropriate place for them. Tested for x86_64, and with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * stdlib/Versions (libc): Move entries for wcstof128 and wcstof128_l to .... * wcsmbs/Versions (libc): ... here.

* Move some float128 symbol version definitions.Joseph Myers2017-10-161-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With support for _Float128 functions on platforms where that type has the same ABI as long double, as well as on platforms where it is ABI-distinct, those functions will need to be exported from glibc's shared libraries at appropriate symbol versions in each case. This patch avoids duplication of lists of symbols to export by moving the symbols other than __* to math/Versions and stdlib/Versions. There, they are conditional on <float128-abi.h> defining FLOAT128_VERSION and a default version of that header is added that does not define that macro. Enabling the float128 function aliases will then include adding a sysdeps/ieee754/ldbl-128/float128-abi.h that defines FLOAT128_VERSION to GLIBC_2.27. Symbols __* remain in sysdeps/ieee754/float128/Versions; those symbols should be present only once per floating-point format, not once per type. Note that if any platforms currently lacking support for a type with binary128 format get glibc support for such a type in future (whether only as _Float128, or also as a new long double format), and new libm functions (present for all types) have been added by then, additional macros will be needed to allow such functions to get a version of the form "GLIBC_2.28 if the platform had _Float128 support by then, or the later version at which that platform had _Float128 support added". This is not however a preexisting condition, but would have applied equally to the existing support for _Float128 as an ABI-distinct type. New all-type libm functions should just be added to the appropriate symbol version (currently GLIBC_2.27) for all types, with such special-case handling for _Float128 versions (and _Float64x as well in future) waiting until someone actually wants to add support for _Float128 to an existing platform after a release in which that platform and a post-2.26 libm function had support but that platform lacked _Float128 support. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. Also tested in conjunction with the remaining changes to enable float128 aliases. * sysdeps/generic/float128-abi.h: New file. * sysdeps/ieee754/float128/Versions (FLOAT128_VERSION): Move non-__prefixed symbols to .... * math/Versions: ... here.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As noted in <https://sourceware.org/ml/libc-alpha/2012-12/msg00240.html>, stdlib/Versions and wcsmbs/Versions list some functions as __strto*_internal and __wcsto*_internal rather than explicitly listing the symbols to be exported (so any new internal function matching one of those patterns would be wrongly added to version GLIBC_2.0), which seems like a bad idea. This patch changes those files to list the exported symbols explicitly. There are still entries in sysdeps/nacl/Versions for __nacl_irt_*, but as GLIBC_PRIVATE symbols that seems less significant.

* Add strfromd, strfromf, and strfroml functionsGabriel F. T. Gomes2016-10-251-0/+4
| | | | | | | ISO/IEC TS 18661-1 adds several functions in the strfrom family to stdlib. This patch adds strfromd, strfromf, and strfroml. This is being done in preparation for the new floating-point type, float128. The added functions convert a floating-point value into a string, with configurable format.
* Bug 20198: quick_exit should not call destructors.Carlos O'Donell2016-06-061-0/+3
| | | | | | | | | | | | | | | | | | In C++11 18.5.12 says "Objects shall not be destroyed as a result of calling quick_exit." In C11 quick_exit is silent about thread object destruction. Therefore to make glibc C++ compliant we do not call any thread local destructors. A new regression test verifies the fix. I will note that C++11 18.5.3 makes it clear that C++ defines additional requirements for _Exit() to prevent it from executing destructors. Given that the point of _Exit() is to terminate the process immediately it makes sense the C and C++ should line up and avoid calling destructors. No failures. New regtest passes.
* Fix nan functions handling of payload strings (bug 16961, bug 16962).Joseph Myers2015-12-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The nan, nanf and nanl functions handle payload strings by doing e.g.: if (tagp[0] != '\0') { char buf[6 + strlen (tagp)]; sprintf (buf, "NAN(%s)", tagp); return strtod (buf, NULL); } This is an unbounded stack allocation based on the length of the argument. Furthermore, if the argument starts with an n-char-sequence followed by ')', that n-char-sequence is wrongly treated as significant for determining the payload of the resulting NaN, when ISO C says the call should be equivalent to strtod ("NAN", NULL), without being affected by that initial n-char-sequence. This patch fixes both those problems by using the __strtod_nan etc. functions recently factored out of strtod etc. for that purpose, with those functions being exported from libc at version GLIBC_PRIVATE. Tested for x86_64, x86, mips64 and powerpc.

| | | | | | | | | | | This feature is specifically for the C++ compiler to offload calling thread_local object destructors on thread program exit, to glibc. This is to overcome the possible complication of destructors of thread_local objects getting called after the DSO in which they're defined is unloaded by the dynamic linker. The DSO is marked as 'unloadable' if it has a constructed thread_local object and marked as 'unloadable' again when all the constructed thread_local objects defined in it are destroyed.
