Tim Northover 99ec36c684 X86: delegate expanding atomic libcalls to generic code. ... On targets without cmpxchg16b or cmpxchg8b, the borderline atomic operations were slipping through the gaps. X86AtomicExpand.cpp was delegating to ISelLowering. Generic ISelLowering was delegating to X86ISelLowering and X86ISelLowering was asserting. The correct behaviour is to expand to a libcall, preferably in generic ISelLowering. This can be achieved by X86ISelLowering deciding it doesn't want the faff after all. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212134 91177308-0d34-0410-b5e6-96231b3b80d8		2014-07-01 21:44:59 +00:00
