* | ARM: use LLVM's atomicrmw instructions when ldrex/strex are available. | Tim Northover | 2014-07-09 | 1 | -0/+35 |
Having some kind of weird kernel-assisted ABI for these when the native instructions are available appears to be (and should be) the exception; OSs have been gradually opting in for years and the code was getting silly. So let LLVM decide whether it's possible/profitable to inline them by default. Patch by Phoebe Buckheister. llvm-svn: 212598 |
