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.
