DEMANGLE

Syntax
DEMANGLE [on|off]
Variable
VT_DEMANGLE
Default
off
Description
Intel® 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.
Note
Some versions of Libstdc++ provide
__cxa_demangle
that does not work properly in all cases.
