Hi! Now that OpenMP 3.1 has been released for a few weeks and what we have on gomp-3_1-branch should be feature complete (though in the future could benefit from various optimizations, in particular: 1) avoid atomic insns for atomic reads and stores if aligned and hw/backend can guarantee atomicity of the store/load - use volatile loads/stores instead - here I hope some interaction with Andrew's C++0x stuff will be useful 2) taskyield - currently stubbed, I think especially if we have a different task scheduler it will be useful to implement it 3) mergeable task clonning), I'd like to merge this to trunk.
Bootstrapped/regtested on x86_64-linux and i686-linux, will commit unless
I hear objections in the next day or so.
