libc, libthr: Ditch MD __pthread_distribute_static_tls helpers

2025-05-29T16:06:54Z

_libc_get_static_tls_base() is just _tcb_get() followed by adding (for Variant I) or subtracting (for Variant II) the offset, so just inline that as the implementation (like we do in rtld-elf) rather than having another copy (or equivalent) of _tcb_get()'s assembly. _get_static_tls_base() doesn't even have any MD assembly as it's reading thr->tcb, the only difference is whether to add or subtract, so again just inline that. Whilst here add some missing blank lines to comply with style(9) for elf_utils.c's includes, and use a pointer type rather than uintptr_t to reduce the need to cast, as is done in rtld-elf.

lib{c,sys}: return wrapped syscall APIs to libc

2024-03-13T18:36:02Z

These provide standard APIs, but are implemented using another system call (e.g., pipe implemented in terms of pipe2) or are interposed by the threading library to support cancelation. After discussion with kib (see D44111), I've concluded that it is better to keep most public interfaces in libc with as little as possible in libsys.

libc: move rfork_thread(3) to libsys

2024-02-05T20:34:56Z

rfork_thread(3) is assembly that makes syscalls directly and uses cerror so it belongs in libsys. Reviewed by: kib, emaste, imp Pull Request: https://github.com/freebsd/freebsd-src/pull/908

libc: Move per-arch sys/Makefile.inc to libsys

2024-02-05T20:34:55Z

libc//sys/Makefile.inc -> libsys//Makefile.sys. Require that libsys//Makefile.sys exist. At least for current archtiectures, it's not possible for an architecture to not have and MD syscall bits. powerpcspe/Makefile.sys's structure means it had to be modified when moved so rename detection won't work, but it has trivial contents so the history is unimportant.
