Struct Amode 

pub struct Amode {
    pub base: Option<u8>,
    pub index: Option<u8>,
    pub scale: u8,
    pub disp: i32,
    pub symbol: Option<Symbol>,
}

A memory addressing mode, as the instruction holds it.

The registers are the indices of the operands holding them rather than the registers themselves, because an address register is a register the allocator has to see and rewrite, and the only thing it looks at is the operand vector. Mem is the same thing written the way a caller writes it, and crate::InstBuilder::mem turns one into the other.

Fields

base: Option<u8>

The operand holding the base register.

index: Option<u8>

The operand holding the index register.

scale: u8

What the index is multiplied by, which is 1 when there is no index.

disp: i32

The constant added to the address.

symbol: Option<Symbol>

The symbol the address is relative to, for an access to a global.
