* Move mutex, condvar, and thread-specific data routes, pthread_once, andguenther2017-09-051-20/+1
| | | | | | | | pthread_exit from libpthread to libc, along with low-level bits to support them. Major bump to both libc and libpthread. Requested by libressl team. Ports testing by naddy@ ok kettenis@
* Less lock contention by using more pools for mult-threaded programs.otto2016-09-011-3/+3

* Use a Thread Information Block in both single and multi-threaded programs.guenther2016-05-071-0/+41
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@
