Enum StackArgs 

pub enum StackArgs {
    RegisterSized,
    Packed,
}

How arguments that did not get a register sit in the argument area.

Variants

RegisterSized

Each argument occupies a whole number of registers’ worth of the argument area, so a char takes eight bytes. Every ELF ABI here.

Packed

Each argument occupies its natural size and alignment, so a char takes one byte.

Darwin arm64. Getting this wrong produces functions whose ninth argument onward is garbage, on Darwin only, which is spec/cross-compile/06-abis.md section 6.3’s first row.
