GNU C Library
summary
The GNU C Library is shipping a microbenchmark suite (used so far to vet libm patches), has integrated systemtap traces into the dynamic loader to trace malloc and pthread slow paths, and has TSX-based transactional memory via TSX patches for pthread mutexes posted for review; 2.18 development aims to close ~54 key bugs and 2 CVEs, add AR64 support from 2.17, and provide bootstrap cross build support. Work remaining includes resolver RFC fixes, splitting sunrpc/tipc, better bug triage, wider microbenchmark coverage and mechanisms for live runtime tunables.
