Avoid .align 0. Clang's integrated assembler actually honors this directive

Use the userspace-visible thread register directly in __cerror instead

Use internal names for __errno, _memcpy, memset, and {,_}{set,long}jmp

Eliminate pointless use of PIC_SYM() Split out DEFS.h from SYS.h like some other archs ok kettenis@ deraadt@

Consistently reference '_end' instead of 'end' in the brk/sbrk implementation

Remove sigreturn declaration and the now-unused libc syscall stub

2016-05-09T23:55:52Z

Use a Thread Information Block in both single and multi-threaded programs.

This stores errno, the cancelation flags, and related bits for each thread and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable! Make libpthread dlopen'able by moving the cancelation wrappers into libc and doing locking and fork/errno handling via callbacks that libpthread registers when it first initializes. 'errno' *must* be declared via now! Clean up libpthread's symbol exports like libc. On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec.

Merge the sigaction() and sigprocmask() overloads/wrappers from libpthread

into libc, and move pthread_sigmask() as well (just a trivial wrapper). This provides consistent handling of SIGTHR between single- and multi-threaded programs and is a step in the merge of all the libpthread overloads, providing some ASM and Makefile bits that the other wrappers will need. ok deraadt@ millert@

Adds hidden _libc_FOO aliases for the system call stubs.

2015-09-10T13:29:09Z

Stop generating _brk and _sbrk symbols: they've already been hidden. Set the ELF symbol size on the syscall stubs. Give the __{min,cur}brk symbols a size and type, and hide more jump labels. alpha, arm, m88k, sh, sparc, and vax assistance miod@ hppa assistance kettenis@ ok deraadt@ miod@

Hide many (194!) symbols that nothing should be using.

Delete exect(2); it wasn't portable across archs and nothing used it. ports test build by naddy@ ok deraadt@ kettenis@

Make pthread_atfork() track the DSO that called it like atexit() does,

unregistering callbacks if the DSO is unloaded. Move the callback handling from libpthread to libc, though libpthread still overrides the inner call to handle locking and thread-library reinitialization. Major version bump for both libc and libpthread. verification that this fixes various ports ajacoutot@ asm assistance miod@; ok millert@ deraadt@
