@ -65,6 +65,12 @@ Version 2.18
* Added new API functions pthread_getattr_default_np and
pthread_setattr_default_np to get and set the default pthread
attributes of a process.
* Added support for TSX lock elision for pthread mutexes on i386 and x86-64.
This may improve lock scaling of existing programs on TSX capable systems.
When the --enable-lock-elision=yes parameter is specified at configure
time lock elision will be enabled by default for all PTHREAD_MUTEX_DEFAULT
mutexes.
