* 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>

* hurd: Make it possible to call memcpy very earlySergey Bugaev2023-05-011-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally, in static builds, the first code that runs is _start, in e.g. sysdeps/x86_64/start.S, which quickly calls __libc_start_main, passing it the argv etc. Among the first things __libc_start_main does is initializing the tunables (based on env), then CPU features, and then calls _dl_relocate_static_pie (). Specifically, this runs ifunc resolvers to pick, based on the CPU features discovered earlier, the most suitable implementation of "string" functions such as memcpy. Before that point, calling memcpy (or other ifunc-resolved functions) will not work. In the Hurd port, things are more complex. In order to get argv/env for our process, glibc normally needs to do an RPC to the exec server, unless our args/env are already located on the stack (which is what happens to bootstrap processes spawned by GNU Mach). Fetching our argv/env from the exec server has to be done before the call to __libc_start_main, since we need to know what our argv/env are to pass them to __libc_start_main. On the other hand, the implementation of the RPC (and other initial setup needed on the Hurd before __libc_start_main can be run) is not very trivial. In particular, it may (and on x86_64, will) use memcpy. But as described above, calling memcpy before __libc_start_main can not work, since the GOT entry for it is not yet initialized at that point. Work around this by pre-filling the GOT entry with the baseline version of memcpy, __memcpy_sse2_unaligned. This makes it possible for early calls to memcpy to just work. The initial value of the GOT entry is unused on x86_64, and changing it won't interfere with the relocation being performed later: once _dl_relocate_static_pie () is called, the baseline version will get replaced with the most suitable one, and that is what subsequent calls of memcpy are going to call.
