1//! Semihosting operations
2//!
3//! The details of what each operation does can be found in the
4//! [ARM Semihosting Specification](https://github.com/ARM-software/abi-aa/blob/main/semihosting/semihosting.rst#semihosting-operations).
5//! The RISC-V Semihosting operations are identiacal to ARM's, so their
6//! documentation is sufficient.
