They are mostly left-overfrom the $FreeBSD$ removal. A few in libc are still required for macrosthat cdefs.h defines. Keep those.Sponsored by: NetflixDifferential Revision: https://reviews.freebsd.org/D42385(cherry picked from commit 559a218c9b257775fb249b67945fe4a05b7a6b9f) List of files: /freebsd-14.2/lib/libc/sys/wait4.c Wed, 01 Nov 2023 22:43:37 +0000 Warner Losh <imp@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/lib/libc/sys/wait4.c#1d386b48 Remove $FreeBSD$: one-line .c patternRemove /^[\s*]*__FBSDID\("\$FreeBSD\$"\);?\s*\n/ List of files: /freebsd-14.2/lib/libc/sys/wait4.c Wed, 16 Aug 2023 17:54:42 +0000 Warner Losh <imp@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/lib/libc/sys/wait4.c#560e22c8 Remove "All Rights Reserved" from FreeBSD Foundation libc copyrightsAs per the updated FreeBSD copyright template.

Instead, functions calls are indirected through the interposing table, similar to how pthread stubs in libc are already done. Libc by default points either to syscall trampolines or to existing libc implementations. On libthr load, libthr rewrites the pointers to the cancellable implementations already in libthr. The interposition table is separate from pthreads stubs indirection table to not pull pthreads stubs into static binaries.- Postpone the malloc(3) internal mutexes initialization until libthr is loaded. This avoids recursion between calloc(3) and static pthread_mutex_t initialization.- Reinstall signal handlers with wrapper on libthr load. The _rtld_is_dlopened(3) is used to avoid useless calls to sigaction(2) when libthr is statically referenced from the main binary.In the process, fix openat(2), swapcontext(2) and setcontext(2)interposing. The libc symbols were exported at different versionsthan libthr interposers. Export both libc and libthr versions fromlibc now, with default set to the higher version from libthr.Remove unused and disconnected swapcontext(3) userspace implementationfrom libc/gen.No objections from: deischenTested by: pho, antoine (exp-run) (previous versions)Sponsored by: The FreeBSD FoundationMFC after: 1 week List of files: /freebsd-14.2/lib/libc/sys/wait4.c Sat, 03 Jan 2015 18:38:46 +0000 Konstantin Belousov <kib@FreeBSD.org>
