DEMANGLE

Syntax

DEMANGLE [on|off]

Variable

VT_DEMANGLE

Default

off

Description

Intel® Trace Analyzer and 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 Analyzer and 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.
