* hurd: Align signal stack pointer after allocating stackframeSergey Bugaev2023-05-161-3/+2
| | | | | | | | | | | sizeof (*stackframe) appears to be divisible by 16, but we should not rely on that. So make sure to leave enough space for the stackframe first, and then align the final pointer at 16 bytes. Checked on x86_64-gnu.

* libio: Add __nonnull for FILE * arguments of fclose and freopenXi Ruoyao2023-05-161-3/+3
| | | | | | | | | | Calling fclose or freopen with a null FILE * is undefined behavior, and doing so in practice will cause a SIGSEGV. So it seems suitable for __nonnull. This will help the compiler to warn for some buggy code, like https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109570. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* nss: Reconcile conditional declaration and use of `is_nscd'Arjun Shankar2023-05-161-3/+3
| | | | | | | | | | | | | This change harmonizes the declaration and use of `is_nscd' and fixes a build failure with the "--enable-static-nss --enable-nscd" configuration options due to `is_nscd' being used undeclared. The purpose of `is_nscd' is to avoid (nss <-> nscd) recursion in dynamically linked libc (SHARED) that is nscd-aware (USE_NSCD), and so its declaration and use should be guarded by the definition of those macros.

* hurd: rule out some mach headers when generating errno.hSamuel Thibault2023-05-112-3/+4
| | | | | | | | | | While mach/kern_return.h happens to pull mach/machine/kern_return.h, mach/machine/boolean.h, and mach/machine/vm_types.h (and realpath-ing them exposes the machine-specific machine symlink content), those headers do not actually define anything machine-specific for the content of errno.h. So we can just rule out these machine-specific from the dependency comment.
* Stop checking if MiG supports retcode.Flavio Cruz2023-05-113-65/+0
| | | | | | | | | | | | | | | | We already did the same change for Hurd (https://git.savannah.gnu.org/cgit/hurd/hurd.git/commit/?id=ef5924402864ef049f40a39e73967628583bc1a4) Due to MiG requiring the subsystem to be defined early in order to know the size of a port, this was causing a division by zero error during ./configure. We could have just move subsystem to the top of the snippet, however it is simpler to just remove the check given that we have no plans to use some other MiG anyway. HAVE_MIG_RETCODE is removed completely since this will be a no-op either way (compiling against old Hurd headers will work the same, new Hurd headers will result in the same stubs since retcode is a no-op).

This assumes that mach_msg_type_t is always the same size as int which is not true for x86_64. - Calculate the size and align using PTR_ALIGN_UP, which is a bit cleaner and similar to what we do elsewhere. - Define mach_msg_type_t to check using designated initializers.

* Enable libmvec support for AArch64Joe Ramsay2023-05-0332-19/+983
| | | | | | | | | | | | | | | | | | | | | | | This patch enables libmvec on AArch64. The proposed change is mainly implementing build infrastructure to add the new routines to ABI, tests and benchmarks. I have demonstrated how this all fits together by adding implementations for vector cos, in both single and double precision, targeting both Advanced SIMD and SVE. The implementations of the routines themselves are just loops over the scalar routine from libm for now, as we are more concerned with getting the plumbing right at this point. We plan to contribute vector routines from the Arm Optimized Routines repo that are compliant with requirements described in the libmvec wiki. Building libmvec requires minimum GCC 10 for SVE ACLE. To avoid raising the minimum GCC by such a big jump, we allow users to disable libmvec if their compiler is too old. Note that at this point users have to manually call the vector math functions. This seems to be acceptable to some downstream users. Reviewed-by: Szabolcs Nagy <szabolcs.nagy@arm.com>
