Method goto_top

cranelift/codegen/src/cursor.rs:290–293

Go to the top of `block` which must be inserted into the layout. At this position, instructions cannot be inserted, but `next_inst()` will move to the first instruction in `block`.

(&mut self, block: ir::Block)

    /// At this position, instructions cannot be inserted, but `next_inst()` will move to the first
    /// instruction in `block`.
    fn goto_top(&mut self, block: ir::Block) {
        debug_assert!(self.layout().is_block_inserted(block));
        self.set_position(CursorPosition::Before(block));
    }

    /// Go to the bottom of `block` which must be inserted into the layout.
    /// At this position, inserted instructions will be appended to `block`.
