- Update to glibc 2.20 release.
* Reverted change of ABI data structures for s390 and s390x
* Support for file description locks is added to systems running the
Linux kernel
* Optimized strchr implementation for AArch64
* The minimum Linux kernel version that this version of the GNU C Library
can be used with is 2.6.32
* Running the testsuite no longer terminates as soon as a test fails
* The am33 port, which had not worked for several years, has been removed
from ports.
* The _BSD_SOURCE and _SVID_SOURCE feature test macros are no longer
supported; they now act the same as _DEFAULT_SOURCE (but generate a
warning)
* Optimized strcmp implementation for ARMv7
* Added support for TX lock elision of pthread mutexes on s390 and s390x
* All supported architectures now use the main glibc sysdeps directory
instead of some being in a separate "ports" directory
* The NPTL implementation of POSIX pthreads is no longer an "add-on"
* Locale names, including those obtained from environment variables (LANG
and the LC_* variables), are more tightly checked for proper syntax
* On x86-64, the dynamic linker's lazy-binding support is now compatible
with application code using Intel MPX instructions
- Patches from upstream removed
* nss-dns-memleak.patch
* sin-sign.patch
* pldd-wait-ptrace-stop.patch
* nscd-track-startup-failures.patch
* powerpc-opt-power8.patch
* check-pf-alloca.patch
* getaddrinfo-uninit-result.patch
