            Bug ID: 48009
           Summary: _ExtInt example doesn't demangle, but does in c++filt
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: llvm-c++filt
          Assignee: unassignedbugs at nondot.org
          Reporter: erich.keane at intel.com
                CC: llvm-bugs at lists.llvm.org

bash-4.2$ c++filt
'_Z29__spirv_ArbitraryFloatEQINTELILi79ELi79EEbU7_ExtIntIXT_EEiiU7_ExtIntIXT0_EEii'
bool __spirv_ArbitraryFloatEQINTEL<79, 79>(int _ExtInt<79>, int, int
_ExtInt<79>, int)
bash-4.2$ ./llvm-cxxfilt
'_Z29__spirv_ArbitraryFloatEQINTELILi79ELi79EEbU7_ExtIntIXT_EEiiU7_ExtIntIXT0_EEii'
_Z29__spirv_ArbitraryFloatEQINTELILi79ELi79EEbU7_ExtIntIXT_EEiiU7_ExtIntIXT0_EEii


For some reason, llvm-cxxfilt cannot demangle that, but it does in GNU's
demangler (also on demangler.com).  Currently doesn't work on 'trunk' as of
today, and c++filt is from binutils 2.32.
