            Bug ID: 23354
           Summary: Missing LLVM-C interface for building atomic compare
                    exchange instructions
           Product: libraries
           Version: 3.6
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: Core LLVM classes
          Assignee: unassignedbugs at nondot.org
          Reporter: coder0xff at gmail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

The LLVMBuildAtomicRMW function doesn't seem to support an op code for compare
exchange, and I couldn't find a function for building compare exchange in
specific. It's either missing, or I just had no luck searching for it.
