protozorq writes "In mid Nov. the GNU GCC project announced to support transactional memory (TM) in their future C/C++ compilers, currently available as experimental feature in the version 4.7.0 branch. The support mainly consists of a language extension to mark critical sections for transactions and a suitable Application Binary Interface (ABI) to attach appropriate compiler backends and their TM libraries (see http://gcc.gnu.org/wiki/TransactionalMemory). Language extension and ABI are almost similar to those of the prototypical Intel compiler also supporting TM."
