__declspec is not a core Clang language extension. Instead, require -fms-extensions or -fborland to enable the language extension. Note: __declspec is also temporarily enabled when compiling for a CUDA target because there are implementation details relying on __declspec(property) support currently. When those details change, __declspec should be disabled for CUDA targets. llvm-svn: 238238

CodeGen: support dll{ex,im}port on WoA Add ARM support for dllexport and dllimport attributes. This is a relatively conservative change. The alternative is to entirely drop the architecture requirement. The dllimport and dllexport attributes are not restricted to any architecture, simply to platforms that support this attribute (currently Windows). llvm-svn: 208486

Bring r325915 back. The tests that failed on a windows host have been fixed. Original message: Start setting dso_local for COFF. With this there are still some GVs where we don't set dso_local because setGVProperties is never called. I intend to fix that in followup commits. This is just the bare minimum to teach shouldAssumeDSOLocal what it should do for COFF. llvm-svn: 325940
