Struct MInstr 

pub struct MInstr {
    pub opcode: MOpcode,
    pub dst: Option<VReg>,
    pub operands: Vec<MOperand>,
    pub phys_uses: Vec<PReg>,
    pub clobbers: Vec<PReg>,
    pub debug_loc: Option<DebugLoc>,
}

A single machine instruction.

Fields

opcode: MOpcode

Target-specific opcode.

dst: Option<VReg>

Output (destination) virtual register, if any.

operands: Vec<MOperand>

Input operands (source registers, immediates, branch targets).

phys_uses: Vec<PReg>

Physical registers that must hold specific values before this instruction (e.g. argument registers at a call site).

clobbers: Vec<PReg>

Physical registers whose values are destroyed by this instruction (e.g. caller-saved regs clobbered by a call).

debug_loc: Option<DebugLoc>

Source debug location associated with this machine instruction.
