[LLVMdev] AsmWriter.cpp:255: error: ambiguous overload for `std::basic_ostream<char,...

[Reid Spencer]

Not sure if this will help, but something is terribly wrong, possibly with 
the definition of int64_t.  Note that the message from the compiler is not 
"can't find overload" but it is "ambiguous overload". It provides what it 
thinks is a close match, that being an operator<< that takes a pointer to a 
function returning basic_ostream<char>& and taken basic_ostream<char>& as an 
argument. Why would it attempt to match an int64_t with a function pointer?

Reid.
