[LLVMdev] possible bug in COFFObjectFile::getSymbolType()
...ut the test is (read & !write), so the symbol gets marked as ST_Data instead of ST_Other.

Are either of those set on the section in question? It may make more sense to try to key off of those section characteristics as well. On Fri, Aug 22, 2014 at 9:55 AM, Ted Woodward <ted.w...

[LLVMdev] possible bug in COFFObjectFile::getSymbolType()
...type SymbolRef::ST_Data instead of disassembling them. This causes llvm/test/MC/ARM/Windows/mov32t-range.s to fail, because the symbol "truncation" comes back as SymbolRef::ST_Data, and the code gets dumped as bytes instead of disassembled. I traced the problem back to COFFObjectFile::getSymbolType() in llvm/lib/Object/COFFObjectFile.cpp : if (Characteristics & COFF::IMAGE_SCN_MEM_READ && ~Characteristics & COFF::IMAGE_SCN_MEM_WRITE) // Read only. Result = SymbolRef::ST_Data; I think it should also check for ~Characteristics & COFF::IMAGE_SCN_MEM_...
