[LLVMdev] Reviving the new LLVM concurrency model
...r of locks must be larger than the number of unlocks in the same
thread... for enabling some optimizations, for example, simplifying
trylocks (http://www.hpl.hp.com/techreports/2008/HPL-2008-56.html),
and moving some instructions inside lock acquires
(http://www.hpl.hp.com/techreports/2005/HPL-2005-217R1.html). What is
the rationale that the LLVM memory model ignores such restrictions?

[LLVMdev] Reviving the new LLVM concurrency model
There was some discussion a while back about adding a C++0x-style
memory model and atomics for LLVM a while back
(http://thread.gmane.org/gmane.comp.compilers.llvm.devel/31295), but
it got stalled. I'm going to try and restart progress on it.
Attached are two patches; the first adds a section to LangRef with
just the memory model, without directly changing the documentation or
implementation
