2015-09-11Move bits/atomic.h to atomic-machine.h (bug 14912).Joseph Myers1-119/+0
It was noted in <https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the bits/*.h naming scheme should only be used for installed headers. This patch renames bits/atomic.h to atomic-machine.h to follow that convention. This is the only change in this series that needs to change the filename rather than simply removing a directory level (because both atomic.h and bits/atomic.h exist at present). Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch).

2015-07-28ia64: atomic.h: fix atomic_exchange_and_add 64bit handlingMike Frysinger1-3/+1
Way back in 2005 the atomic_exchange_and_add function was cleaned up to avoid the explicit size checking and instead let gcc handle things itself. Unfortunately that change ended up leaving beyond a cast to int, even when the incoming value was a long. This has flown under the radar for a long time due to the function not being heavily used in the tree (especially as a full 64bit field), but a recent change to semaphores made some nptl tests fail reliably. This is due to the code packing two 32bit values into one 64bit variable (where the high 32bits contained the number of waiters), and then the whole variable being atomically updated between threads. On ia64, that meant we never atomically updated the count, so sometimes the sem_post would not wake up the waiters.

2014-11-20Add arch-specific configuration for C11 atomics support.Torvald Riegel1-0/+3
This sets __HAVE_64B_ATOMICS if provided. It also sets USE_ATOMIC_COMPILER_BUILTINS to true if the existing atomic ops use the __atomic* builtins (aarch64, mips partially) or if this has been tested (x86_64); otherwise, this is set to false so that C11 atomics will be based on the existing atomic operations.
