The ELF format is used on Windows by the MCJIT engine. Thus, on Windows, the ELFObjectWriter can encounter symbols mangled using the MS Visual Studio C++ name mangling. Symbols mangled using the MSVC C++ name mangling can legally have "@@@" as a substring. The EFLObjectWriter should not interpret the "@@@" substring as specifying GNU-style symbol versioning. The ELFObjectWriter therefore check for the MSVC C++ name mangling prefix which is either "?", "@?", "imp_?" or "imp_?@". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@226830 91177308-0d34-0410-b5e6-96231b3b80d8
