IntelĀ® Trace Collector 9.1 Update 2 User and Reference Guide
DEMANGLE [on|off]
VT_DEMANGLE
off
IntelĀ® Trace Collector automatically demangles mangled names if this switch is enabled. Name demangling is used in compiler driven instrumentation and in correctness checking reports. Intel® Trace Collector uses __cxa_demangle from the C++ ABI or UnDecorateSymbolName on Windows* OS. On Linux* OS demangling C++ names only works with the naming scheme used by GCC 3.x and newer compilers.
Some versions of Libstdc++ provide __cxa_demangle that does not work properly in all cases.
