A trait all InstructionWriters share.

Required Methods

fn new(code_address: u64) -> Self

Create a new InstructionWriter to write code to the given address

fn pc(&self) -> u64

Retrieve the writer’s current program counter.

fn code_offset(&self) -> u64

Retrieve the writer’s current code offset.

fn can_branch_directly_between(&self, source: u64, target: u64) -> bool

Check if we can branch directly between the given source and target addresses.

fn put_bytes(&self, bytes: &[u8]) -> bool

Add the bytes specified to the instruction stream.

fn put_label(&self, id: u64) -> bool

Add a label at the curent point in the instruction stream.

fn reset(&self, code_address: u64)

Reset the writer to the given code address

fn put_branch_address(&self, address: u64) -> bool

Add a branch to an immediate address

fn flush(&self) -> bool

Flush the writer, outputing any pending ldr-immediates

Provided Methods

fn can_branch_directly_to(&self, target: u64) -> bool

Check if we can branch directly to the target address from the current program counter.
