[llvm-dev] Problem Compiling AsmParser

[Sky Flyer via llvm-dev]

Thanks Nakamura, that was actually a nice hint.
I added the follow lines (copied from ARMAsmParser.cpp) to the end of my
TestAsmParser.cpp file and it seems like the problem is solved during the
compilation time, though I haven't tested it yet to see if the binary works
as well!

#define GET_REGISTER_MATCHER
#define GET_SUBTARGET_FEATURE_NAME
#define GET_MATCHER_IMPLEMENTATION
#include "TestGenAsmMatcher.inc"

Cheers,
ES
