Struct MaterializeOpsVisitor

pub struct MaterializeOpsVisitor<B> { /* private fields */ }

Available on crate feature decode only.

A visitor that materializes whole Ops as it decodes the bytecode stream.

Implementations

impl<B> MaterializeOpsVisitor<B>

pub fn new(bytecode: B) -> Self

Create a new op-materializing visitor for the given bytecode.

Trait Implementations

impl<B: Default> Default for MaterializeOpsVisitor<B>

fn default() -> MaterializeOpsVisitor<B>

Returns the “default value” for a type.

impl<B: BytecodeStream> ExtendedOpVisitor for MaterializeOpsVisitor<B>

fn trap(&mut self) -> Self::Return

Raise a trap.

fn nop(&mut self) -> Self::Return

Do nothing.

fn call_indirect_host(&mut self, id: u8) -> Self::Return

A special opcode to halt interpreter execution and yield control back to the host.

This opcode results in DoneReason::CallIndirectHost where the id here is shepherded along to the embedder. It’s up to the embedder to determine what to do with the id and the current state of registers and the stack.

In Wasmtime this is used to implement interpreter-to-host calls. This is modeled as a call instruction where the first parameter is the native function pointer to invoke and all remaining parameters for the native function are in following parameter positions (e.g. x1, x2, …). The results of the host call are then store in x0.

Handling this in Wasmtime is done through a “relocation” which is resolved at link-time when raw bytecode from Cranelift is assembled into the final object that Wasmtime will interpret.

fn xmov_fp(&mut self, dst: XReg) -> Self::Return
