Struct Call 

pub struct Call { /* private fields */ }

The registers one call has left.

Made by TargetInfo::call, asked about the return value first and then about each argument in order. Asking out of order gives an answer for a different program.

Implementations

impl Call

pub fn returns(&mut self, arg: &Arg<'_>) -> Pass

How the return value comes back, which is asked before anything else.

A return value that comes back in memory takes an argument register with it on three of these four ABIs, so asking about the arguments first gives the wrong answer for the last one of them.

pub fn argument(&mut self, arg: &Arg<'_>) -> Pass

How the next argument travels, which spends whatever registers it takes.

Trait Implementations

impl Debug for Call

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
