I've created svn://gcc.gnu.org/svn/gcc/branches/transactional-memory/
for the development of support for transactional memory within gcc. This branch will track mainline gcc. There are some folks that have already been working on this project; their page is at http://www.hipeac.net/node/2419 So far, I've applied their patch (which is vs 4.3) against mainline, fixed up *.rej, and committed the result. I've not yet gone through their patch to convert it to tuples, or anything else that would let it compile. That I'll begin doing next week. Please mark anything related to this branch with [trans-mem]. Cheers, r~
