Expand description

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[src]

Get the current position.

fn put1(&mut self, _: u8)[src]

Add 1 byte to the code section.

fn put2(&mut self, _: u16)[src]

Add 2 bytes to the code section.

fn put4(&mut self, _: u32)[src]

Add 4 bytes to the code section.

fn put8(&mut self, _: u64)[src]

Add 8 bytes to the code section.

fn reloc_external(
    &mut self,
    _: SourceLoc,
    _: Reloc,
    _: &ExternalName,
    _: Addend
)
[src]

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

fn reloc_constant(&mut self, _: Reloc, _: ConstantOffset)[src]

Add a relocation referencing a constant.

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

Add a relocation referencing a jump table.

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

Add trap information for the current offset.

fn begin_jumptables(&mut self)[src]

Machine code output is complete, jump table data may follow.

fn begin_rodata(&mut self)[src]

Jump table output is complete, raw read-only data may follow.

fn end_codegen(&mut self)[src]

Read-only data output is complete, we’re done.

fn add_stack_map(&mut self, _: &[Value], _: &Function, _: &dyn TargetIsa)[src]

Add a stack map at the current code offset.

Provided methods

fn add_call_site(&mut self, _: Opcode, _: SourceLoc)[src]

Add a call site for a call with the given opcode, returning at the current offset.
