Abstract interface for adding bytes to the code segment.

A CodeSink will receive all of the machine code for a function. It also accepts relocations which are locations in the code section that need to be fixed up when linking.

Required Methods

fn offset(&self) -> CodeOffset

Get the current position.

fn put1(&mut self, _: u8)

Add 1 byte to the code section.

fn put2(&mut self, _: u16)

Add 2 bytes to the code section.

fn put4(&mut self, _: u32)

Add 4 bytes to the code section.

fn put8(&mut self, _: u64)

Add 8 bytes to the code section.

fn reloc_ebb(&mut self, _: Reloc, _: CodeOffset)

Add a relocation referencing an EBB at the current offset.

fn reloc_external(&mut self, _: Reloc, _: &ExternalName, _: Addend)

Add a relocation referencing an external symbol plus the addend at the current offset.

fn reloc_jt(&mut self, _: Reloc, _: JumpTable)

Add a relocation referencing a jump table.

fn trap(&mut self, _: TrapCode, _: SourceLoc)

Add trap information for the current offset.

fn begin_rodata(&mut self)

Code output is complete, read-only data may follow.
