| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the preparation for additional _FloatN / _FloatNx type support, this patch adds support to type-generic strtod tests.

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.

* nptl: Add tests for internal pthread_mutex_t offsetsAdhemerval Zanella2017-11-0719-0/+173
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new build test to check for internal fields offsets for user visible internal field. Although currently the only field which is statically initialized to a non zero value is pthread_mutex_t.__data.__kind value, the tests also check the offset of __kind, __spins, __elision (if supported), and __list internal member. A internal header (pthread-offset.h) is added to each major ABI with the reference value.

* Do not declare _Float128 support for powerpc64le -mlong-double-64 (bug 22402).Joseph Myers2017-11-062-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Clean up complex.h handling of float128.Joseph Myers2017-11-012-15/+21
| | | | | | | | | | | | | | | | | | | This patch cleans up the way complex.h handles inclusion of bits/cmathcalls.h for float128. The inclusion was between those for the types float and long double; the patch moves it after that for long double, matching how bits/mathcalls.h and bits/math-finite.h inclusions are ordered. There is no need for the undefine and define of _Mdouble_complex_ to be conditional, since __CFLOAT128 is always defined by bits/floatn.h when _Float128 is supported, so the patch removes the unnecessary conditionals. Tested for x86_64. * math/complex.h [(__HAVE_DISTINCT_FLOAT128 || (__HAVE_FLOAT128 && !LIBC)) && __GLIBC_USE (IEC_60559_TYPES_EXT)]: Move conditional code after that for long double. Do not condition define and undefine of _Mdouble_complex_ on [__CFLOAT128].
* x86: Add sysdeps/x86/sysdep.hH.J. Lu2017-11-014-85/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new header file, sysdeps/x86/sysdep.h, for common assembly code macros between i386 and x86-64. Tested on i686 and x86-64. There are no differences in outputs of "readelf -a" and "objdump -dw" on all glibc shared objects before and after the patch. * sysdeps/i386/sysdep.h: Include <sysdeps/x86/sysdep.h> instead of <sysdeps/generic/sysdep.h>.
