Some headers required by C++ freestanding implementations that are really really useful are missing, like atomic and type_traits (among others). It would be great if Segger could provide at least the headers required by C++11 freestanding, see en.cppreference.com/w/cpp/freestanding for a list.
The absolute best option would be if segger distributed the full STL as provided by the ARM toolchain, but the minimum conforming freestanding environment would at least be a start.
Thank you for your inquiry.
C++ library support is currently handled in Embedded Studio by an older STL Port which can be downloaded via the Package Manager.
It is based in C++08 with some custom C++11 extensions and can be enabled in project options.
But we are currently planning on providing our own SEGGER run time library for C++ with the latest C++ features by the end of this year.
