New Revision: 256503
URL: http://llvm.org/viewvc/llvm-project?rev=256503&view=rev
Log:
Avoid crash when dumping LocInfoType.
LocInfoType is a helper type used internally inside Sema and Parser, it
does not exist in valid AST. LocInfoType uses code value outside the
range of valid Type codes, as a result, dumping such type causes error.
The fix allows correct dumping LocInfoType.
