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

COFF sections also contain stuff like IMAGE_SCN_CNT_CODE and IMAGE_SCN_CNT_INITIALIZED_DATA. 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.

...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_...
