Custom handler for system instructions ecall and ebreak

Required Methods

fn handle_ecall( &mut self, regs: &mut Regs, memory: &mut Memory, program_counter: &mut PC, ) -> Result<ControlFlow<()>, ExecutionError<Reg::Type, CustomError>>

Handle an ecall instruction

Provided Methods

fn handle_fence(&mut self, pred: u8, succ: u8)

Handle a fence instruction

fn handle_fence_tso(&mut self)

Handle a fence.tso instruction

fn handle_ebreak(&mut self, regs: &mut Regs, memory: &mut Memory, pc: Reg::Type)

Handle an ebreak instruction.

NOTE: the program counter here is the current value, meaning it is already incremented past the instruction itself.
