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.

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
