The main user of semihosting in system mode is standalone binaries compiled with the gnu toolchain using a newlib that targets semihosting. These generally use SYS_HEAPINFO on startup to find out where to put the stack etc, rather than hardwiring it in the linker map. This applies to both M-profile and A-profile. -- PMM
