Enum ArgLoc 

pub enum ArgLoc {
    Reg(PReg),
    Stack(u32),
}

Where one argument or return value lives at the call.

Examples

use backend_lang::target::abi::{ArgClass, ArgLoc};
use backend_lang::x86_64::WIN64;

let mut locs = Vec::new();
WIN64.assign_args(&[ArgClass::Int; 5], &mut locs);
// The fifth argument goes above the 32 bytes of shadow space.
assert_eq!(locs[4], ArgLoc::Stack(32));

Variants

Reg(PReg)

In a register.

Stack(u32)

On the stack, at this byte offset from the stack pointer at the call instruction (before the return address is pushed). In the callee it is the same offset from the canonical frame address; an incoming stack slot (SlotKind::Incoming) names it.
