Embedded Memory Explorer fails to Demangle some template names. I believe this may have to do with providing a class literal as a template type(C++20). arm-none-eabi-c++filt.exe in the GCC 14.2.1 toolchain properly decodes the following example Embedded Memory Explorer fails on:

Could Sysprog either fix this or provide a way to plugin custom demanglers? A plugin method would be welcome as then the char arrays could be displayed as strings.
Hi,
No problem, the demangler is already a separate DLL with a very simple interface (demangle.dll/demangle64.dll).
#include <cxxabi.h> #include <stdlib.h> extern "C" char *__declspec(dllexport) DemangleCXXName2(const char *pName) { int status = -1; return abi::__cxa_demangle(pName, 0, 0, &status); } extern "C" void __declspec(dllexport) FreeDemangledCXXName(char *pName) { free(pName); }You can build with MinGW using the following command line:
g++.exe demangle.cpp -o demangle.dll -shared -static-libgcc -static-libstdc++
We will update the version shipped with VisualGDB based on the latest MinGW toolchain in the final v6.1 release.
