* i386: In makecontext, align the stack before calling exit [BZ #22667]Florian Weimer2018-01-042-1/+243
| | | | | | Before this change, if glibc was compiled with SSE instructions and a sufficiently recent GCC, an unaligned stack access in __run_exit_handlers would cause stdlib/tst-makecontext to crash.

* Simplify tilegx sysdeps folderAdhemerval Zanella2017-12-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With tilepro support removal we can now simplify internal tile support by moving the directory structure to avoid the unnecessary directory levels in tile/tilegx both on generic and linux folders. Checked with a build for tilegx-linux-gnu and tilegx-linux-gnu-32 with and without the patch, there is no difference in generated binary with a dissassemble. * stdlib/bug-getcontext.c (do_test): Remove tilepro mention in comment. * sysdeps/tile/preconfigure: Remove tilegx folder. * sysdeps/tile/tilegx/Implies: Move definitions to ... * sysdeps/tile/Implies: ... here. * sysdeps/tile/tilegx/Makefile: Move rules to ... * sysdeps/tile/Makefile: ... here. * sysdeps/tile/tilegx/atomic-machine.h: Move definitions to ... * sysdeps/tile/atomic-machine.h: ... here.

* Fix testing with read-only source directory.Joseph Myers2017-12-151-1/+1
| | | | | | | | | | | | | | | | | | | | | Three tests fail with a read-only source directory because they try to write into the source directory. None of these write into it in a way that should actually be problematic for concurrent builds sharing the same writable source directory, but avoiding any writing into the source directory (from testing, or from building glibc if the source timestamps are properly ordered) is still a good idea, as being able to build with read-only sources helps make sure there isn't anything that could cause problems for concurrent builds. This patch changes the tests in question to use either /tmp or the build directory to write their temporary files (or to test O_TMPFILE, as applicable). Tested for x86_64. * io/Makefile (tst-open-tmpfile-ARGS): New variable. * posix/tst-mmap-offset.c (fname): Use /tmp. * stdlib/tst-setcontext3.sh (tempfile): Use ${objpfx}.

* 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.

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 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.

* Fix BZ# 22180.Paul Pluzhnikov2017-09-214-4/+171
| | | | | | | | | | | | | | | | | | | POSIX requires that dlclose() and exit() be thread safe, therefore you can have one thread in the middle of dlclose() and another thread executing exit() without causing any undefined behaviour on the part of the implementation. The existing implementation had a flaw that exit() exit handler processing did not consider a concurrent dlclose() and would not mark already run exit handlers using the ef_free flavour. The consequence of this is that a concurrent exit() with dlclose() will run all the exit handlers that dlclose() had not yet run, but then will block on the loader lock. The concurrent dlclose() will continue to run all the exit handlers again (twice) in violation of the Itanium C++ ABI requirements for __cxa_atexit(). This commit fixes this by having exit() mark all handlers with ef_free to ensure that concurrent dlclose() won't re-run registered exit handlers that have already run.

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. Adjust commentary. Only define struct __locale_struct and __locale_t, not locale_t. * locale/bits/types/locale_t.h: New file; define locale_t here. * locale/Makefile (headers): Update to match. * include/xlocale.h: Delete wrapper. * include/bits/types/__locale_t.h: New wrapper. * include/bits/types/locale_t.h: New wrapper. * ctype/ctype.h, include/printf.h, include/time.h * locale/langinfo.h, locale/locale.h, stdlib/monetary.h * stdlib/stdlib.h, string/string.h, string/strings.h, time/time.h * wcsmbs/wchar.h, wctype/wctype.h: Use bits/types/locale_t.h. Correct outdated comments regarding the standardization status of the functions that take locale_t arguments. * stdlib/strtod_l.c, stdlib/strtof_l.c, stdlib/strtol_l.c * stdlib/strtold_l.c, stdlib/strtoul_l.c, stdlib/strtoull_l.c * sysdeps/ieee754/ldbl-128ibm/strtold_l.c * sysdeps/ieee754/ldbl-64-128/strtold_l.c * wcsmbs/wcstod.c, wcsmbs/wcstod_l.c, wcsmbs/wcstof.c * wcsmbs/wcstof_l.c, wcsmbs/wcstold.c, wcsmbs/wcstold_l.c: Don't include xlocale.h. If necessary, include locale.h instead. * stdlib/strtold_l.c: Unconditionally include wchar.h.
* Remove __need macros from errno.h (__need_Emath, __need_error_t).Zack Weinberg2017-06-141-37/+25

There is no reason why these nonstandard headers cannot just go ahead and include all of errno.h; so we do that. __need_Emath is defined only by .S files; what they _really_ need is for errno.h to avoid declaring anything other than the E-constants (e.g. 'extern int __errno_location(void);' is a syntax error in assembly language). This is replaced with a check for __ASSEMBLER__ in errno.h, plus a carefully documented requirement for bits/errno.h not to define anything other than macros. That in turn has the consequence that bits/errno.h must not define errno - fortunately, all live ports use the same definition of errno, so I've moved it to errno.h. The Hurd bits/errno.h must also take care not to define error_t when __ASSEMBLER__ is defined, which involves repeating all of the definitions twice, but it's a generated file so that's okay. * stdlib/errno.h: Remove __need_Emath and __need_error_t logic. Reorganize file. Declare errno here. When __ASSEMBLER__ is defined, don't declare anything other than the E-constants. * include/errno.h: Change conditional for exposing internal declarations to (not _ISOMAC and not __ASSEMBLER__). * bits/errno.h: Remove logic for __need_Emath. Document requirements for a port-specific bits/errno.h. * sysdeps/unix/sysv/linux/bits/errno.h * sysdeps/unix/sysv/linux/alpha/bits/errno.h * sysdeps/unix/sysv/linux/hppa/bits/errno.h * sysdeps/unix/sysv/linux/mips/bits/errno.h * sysdeps/unix/sysv/linux/sparc/bits/errno.h: Add multiple-include guard and check against improper inclusion. Remove __need_Emath logic. Don't declare errno here. Ensure all constants are defined as simple integer literals. Consistent formatting. * sysdeps/mach/hurd/errnos.awk: Likewise. Only define error_t and enum __error_t_codes if __ASSEMBLER__ is not defined. * sysdeps/mach/hurd/bits/errno.h: Regenerate. * argp/argp.h, string/argz.h: Don't define __need_error_t before including errno.h. * sysdeps/i386/i686/fpu/multiarch/s_cosf-sse2.S * sysdeps/i386/i686/fpu/multiarch/s_sincosf-sse2.S * sysdeps/i386/i686/fpu/multiarch/s_sinf-sse2.S * sysdeps/x86_64/fpu/s_cosf.S * sysdeps/x86_64/fpu/s_sincosf.S * sysdeps/x86_64/fpu/s_sinf.S: Just include errno.h; don't define __need_Emath or include bits/errno.h directly.
