	  Semihosting is a mechanism that enables code running on an ARM or
	  RISC-V target to communicate and use the Input/Output facilities on
	  a host computer that is running a debugger.
	  Additional information can be found in:

	  https://github.com/riscv/riscv-semihosting-spec/blob/main/riscv-semihosting-spec.adoc
	  This option is compatible with hardware and with QEMU, through the
	  (automatic) use of the -semihosting-config switch when invoking it.
