2017-11-11resolv: Use test framework in tst-resolv-networkFlorian Weimer
The main function was left in place by accident when the test was imported.
2017-11-09Add jmp_buf-macros.hH.J. Lu
Verify that sizes, alignments and field offsets of jmp_buf as well as sigjmp_buf are unchanged regardless how struct __jmp_buf_tag is defined. Since jmp_buf is target specific, jmp_buf-macros.h is added for each Linux target. A new target must provides its own jmp_buf-macros.h. TODO: Hurd needs to provide a jmp_buf-macros.h.

2017-11-07Handle more _FloatN, _FloatNx types in include/float.h.Joseph Myers
Continuing the preparation for additional _FloatN / _FloatNx type support, this patch adds support in include/float.h. This header defines macros for _Float128 properties when using compilers before GCC 7 that lack those macros in <float.h>. For testing _Float32 / _Float64 / _Float32x / _Float64x functions with older compilers, such macros need to be defined for those types as well; for the older compilers, those types will always be typedefs for another type, so the definitions can be in terms of the macros for that other type.

2017-11-07nptl: Define __PTHREAD_MUTEX_{NUSERS_AFTER_KIND,USE_UNION}Adhemerval Zanella
This patch adds two new internal defines to set the internal pthread_mutex_t layout required by the supported ABIS: 1. __PTHREAD_MUTEX_NUSERS_AFTER_KIND which control whether to define __nusers fields before or after __kind. The preferred value for is 0 for new ports and it sets __nusers before __kind. 2. __PTHREAD_MUTEX_USE_UNION which control whether internal __spins and __list members will be place inside an union for linuxthreads compatibility. The preferred value is 0 for ports and it sets to not use an union to define both fields. It fixes the wrong offsets value for __kind value on x86_64-linux-gnu-x32.

2017-11-07nptl: Change tst-typesizes to _Static_assertAdhemerval Zanella
Instead of rely on runtime check to assure correct pthread types size a better strategy would use _Static_assert to trigger an error on build time (and thus allowing to check to potentially ABI breakage on cross-compiling make check).

2017-11-07nptl: Add tests for internal pthread_mutex_t offsetsAdhemerval Zanella
This patch adds a new build test to check for internal fields offsets for user visible internal field.

2017-11-06arm: Implement memchr ifunc selection in CAdhemerval Zanella
This patch refactor ARM memchr ifunc selector to a C implementation. No functional change is expected, including ifunc resolution rules. It also reorganize the ifunc options code: 1. The memchr_impl.S is renamed to memchr_neon.S and multiple compilation options (which route to armv6t2/memchr one) is removed. The code to build if __ARM_NEON__ is defined is also simplified. 2. A memchr_noneon is added (which as build along previous ifunc resolution) and includes the armv6t2 direct. 3. Same as 2. for loader object.

2017-11-06Do not declare _Float128 support for powerpc64le -mlong-double-64 (bug 22402).Joseph Myers
The powerpc bits/floatn.h declares _Float128 support to be present when the compiler supports it for powerpc64le. However, in the case where -mlong-double-64 is used, __MATH_TG does not actually support _Float128; it only supports _Float128 in the distinct-long-double case. This shows up as a build failure when building glibc mainline with GCC mainline, given the recently added sanity check in math.h for configurations supported by __MATH_TG, as the compat code for -mlong-double-64 fails to build. However, the bug was logically present before that change (including in 2.26), just less visible. This patch fixes the build failure by declaring _Float128 to be unsupported in that case. (Of course this can't actually stop users calling the type-generic macros with _Float128 arguments with -mlong-double-64, just as they could be called with other unsupported types on other platforms, but perhaps makes it less likely by making all the type-specific _Float128 interfaces invisible in that case.) Tested compilation for powerpc64le with build-many-glibcs.py. [BZ #22402] * sysdeps/powerpc/bits/floatn.h: Include <bits/long-double.h>. [__NO_LONG_DOUBLE_MATH] (__HAVE_FLOAT128): Define to 0.

2017-11-03Handle more _FloatN, _FloatNx types in tgmath.h.Joseph Myers
Continuing the preparation for additional _FloatN / _FloatNx type support, this patch improves how <tgmath.h> handles such types. Use of #error is added for cases of distinct types that are not supported by the header, to indicate that additional work on the header would be needed if, for example, _Float16 support were added to glibc. Given that #error, types with the same format as other types are handled automatically by the sizeof-based logic, so the only case needing special handling is that where _Float64x exists, has the same format as _Float128, does not have the same format as long double, and is not a typedef for _Float128. In this case (which will apply for powerpc64le once _Float64x support is added to glibc), the __builtin_types_compatible_p calls testing for _Float128 need corresponding calls testing for _Float64x, which this patch adds.

2017-11-03aarch64: Disable lazy symbol binding of TLSDESCSzabolcs Nagy
Always do TLS descriptor initialization at load time during relocation processing to avoid barriers at every TLS access. In non-dlopened shared libraries the overhead of tls access vs static global access is > 3x bigger when lazy initialization is used (_dl_tlsdesc_return_lazy) compared to bind-now (_dl_tlsdesc_return) so the barriers dominate tls access performance. TLSDESC relocs are in DT_JMPREL which are processed at load time using elf_machine_lazy_rel which is only supposed to do lightweight initialization using the DT_TLSDESC_PLT trampoline (the trampoline code jumps to the entry point in DT_TLSDESC_GOT which does the lazy tlsdesc initialization at runtime). This patch changes elf_machine_lazy_rel in aarch64 to do the symbol binding and initialization as if DF_BIND_NOW was set, so the non-lazy code path of elf/do-rel.h was replicated. The static linker could be changed to emit TLSDESC relocs in DT_REL*, which are processed non-lazily, but the goal of this patch is to always guarantee bind-now semantics, even if the binary was produced with an old linker, so the barriers can be dropped in tls descriptor functions. After this change the synchronizing ldar instructions can be dropped as well as the lazy initialization machinery including the DT_TLSDESC_GOT setup. I believe this should be done on all targets, including ones where no barrier is needed for lazy initialization. There is very little gain in optimizing for large number of symbolic tlsdesc relocations which is an extremely uncommon case. And currently the tlsdesc entries are only readonly protected with -z now and some hardennings against writable JUMPSLOT relocs don't work for TLSDESC so they are a security hazard. (But to fix that the static linker has to be changed.) * sysdeps/aarch64/dl-machine.h (elf_machine_lazy_rel): Do symbol binding and initialization non-lazily for R_AARCH64_TLSDESC.

2017-10-31Adjust __MATH_EVAL_FMT2 definition to handle _Float16 better.Joseph Myers
Continuing the preparation for additional _FloatN / _FloatNx type support, this patch adds an additional case in the definition of __MATH_EVAL_FMT2, as used in defining iseqsig: when __FLT_EVAL_METHOD__ is 0 or 32, it adds 0.0f to the arguments, so that the correct function would be selected in the case of _Float16 arguments with excess precision (were glibc to support _Float16, which of course __MATH_TG and other facilities do not at present - and _Float16 support is not part of what this patch series is aiming for, but this particular fix is simple so is included anyway). Tested for x86_64. * math/math.h [__FLT_EVAL_METHOD__ == 0 || __FLT_EVAL_METHOD__ == 32] (__MATH_EVAL_FMT2): Define to add 0.0f.
