Enum cranelift_codegen::isa::x64::args::RegMemImm

pub enum RegMemImm {
    Reg {
        reg: Reg,
    },
    Mem {
        addr: SyntheticAmode,
    },
    Imm {
        simm32: u32,
    },
}

An operand which is either an integer Register, a value in Memory or an Immediate. This can denote an 8, 16, 32 or 64 bit value. For the Immediate form, in the 8- and 16-bit case, only the lower 8 or 16 bits of simm32 is relevant. In the 64-bit case, the value denoted by simm32 is its sign-extension out to 64 bits.

Variants

Reg

A register operand.

Fields

reg: Reg

The underlying register.

Mem

A memory operand.

Fields

addr: SyntheticAmode

The memory address.

Imm

An immediate operand.

Fields

simm32: u32

The immediate value.
