Xcore target ABI requires const data that is externally visible to be handled differently if it has C-language linkage rather than C++ language linkage. Clang now emits ".cp.rodata" section information. All other externally visible constant data will be placed in the DP section. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201144 91177308-0d34-0410-b5e6-96231b3b80d8
