## Support
Currently, A-machine only supports the **unprivileged** RV32IMAC instruction set with a few additional `ecall` syscalls: 63 (sys_read, for fd 0 only), 64 (sys_write, for fd 1 and 2 only) and 93 (sys_exit). For completeness, `fence` instruction is also supported but yields a no-op.

For completeness, `fence` instruction is also supported but yields a no-op, and both `ebreak` and `c.ebreak` are supported to halt execution with a debug message.
