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

Oh right, actually delete this now that __cerror is unused

TIB conversion is complete, so set errno in the syscall stub and eliminate

Remove sigreturn declaration and the now-unused libc syscall stub

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. Testing by various, particularly sthen@ and patrick@ ok kettenis@

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@

Backtrack a little bit and don't try to use the per-thread errno location if

r2 is zero. Some upcoming changes will probably change the offset at which the errno pointer is stored, or might even store errno directly. Instead, call __errno to get the location of errno. Make sure we go through the PLT such that we call the version in libpthread if it is linked in. Set up r30 for this purpose. The ___cerrno function itself remains protected. ok guenther@

Fix previous: restore a PSEUDO_SUFFIX macro to actually handle errno and return

cone of shame guenther@ ok deraadt@

Adds hidden _libc_FOO aliases for the system call stubs.

2015-09-05T06:22:46Z

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. ok deraadt@
