New Revision: 274012
URL: http://llvm.org/viewvc/llvm-project?rev=274012&view=rev
Log:
[SPARC] Allows inlining of atomics for Sparc32 with appropriate store barrier.
The final change is required to extend the back-end's AtomicExpandPass that was
implemented for Sparc (64 bit) and later extended for Sparc (32 bit).
