impl<'a> MacroOpcode<'a> for FunctionBuilder<'a>

fn u32_const(&mut self, value: u32) -> &mut Self

Helper function to reinterpret an u32 as an i32 and inject an i32.const instruction with that reinterpreted value. (Useful to emitting memory addresses.) We cast using the as keyword to accomplish this. See https://github.com/thesuhas/orca/issues/133 for an explanation.

fn u64_const(&mut self, value: u64) -> &mut Self

Helper function to reinterpret an u64 as an i64 and inject an i64.const instruction with that reinterpreted value. (Useful to emitting memory addresses.) We cast using the as keyword to accomplish this. See https://github.com/thesuhas/orca/issues/133 for an explanation.
