* Consistently reference '_end' instead of 'end' in the brk/sbrk implementationguenther2016-05-301-2/+2

* TIB conversion is complete, so set errno in the syscall stub and eliminateguenther2016-05-151-2/+4

* Use a Thread Information Block in both single and multi-threaded programs.guenther2016-05-071-2/+2
| | | | | | | | | | | | | | | | | 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 <errno.h> 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@
* Adds hidden _libc_FOO aliases for the system call stubs.guenther2015-09-051-3/+6
| | | | | | | | 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@
* Hide many (194!) symbols that nothing should be using.guenther2015-08-261-10/+9
| | | | | | | Delete exect(2); it wasn't portable across archs and nothing used it. ports test build by naddy@ ok deraadt@ kettenis@

* Preliminary version for PIC support. Builds and runs standard and profiledrahnds1999-01-281-9/+19
| | | | | just fine. pic version has been compiled, but without a ld.so has not been tested. Needs binutils 2.9.1 or later to build pic version.
* Check-in of powerpc library support.rahnds1996-12-211-0/+32
NOTE: This will not work until the other pieces are checked in. This is primarily the NetBSD powerpc port, with modifications to support ELF.
