The semihosting ABI [1] states: > Multi-byte values in memory must be formatted as pure little-endian or pure > big-endian to match the endianness mapping configuration of the processor. This commits ensures that semihosting data is properly byte-swapped if the guest's CPU is currently in a different runtime-configurable endianness than the host's CPU.
