Struct IrFunction 

pub struct IrFunction {
    pub instructions: Vec<IrInst>,
    pub reg_types: HashMap<Reg, IrType>,
    pub field_types: Vec<IrType>,
    pub num_regs: u32,
}

IR function (single basic block).

Fields

instructions: Vec<IrInst>

Instructions.

reg_types: HashMap<Reg, IrType>

Register types.

field_types: Vec<IrType>

Field types (for load instructions).

num_regs: u32

Number of registers used.
