New Revision: 163859
URL: http://llvm.org/viewvc/llvm-project?rev=163859&view=rev
Log:
Specifically disallow primary-expressions of the form LT_... on the basis of
this decition:
http://sourcerytools.com/pipermail/cxx-abi-dev/2011-August/002422.html .
Failure to disallow this was causing infinite recursion in the demangler when
these symbols show up due to mangling bugs. This patch causes the demangler to
return an invalid mangled name result rather than crash in infinite recursion.
