Function jit_insn_flush_struct 

pub unsafe extern "C" fn jit_insn_flush_struct(
    func: jit_function_t,
    value: jit_value_t,
) -> c_int

Flush a small structure return value out of registers and back into the local variable frame. You normally wouldn’t call this yourself - it is used internally by the CPU back ends to handle structure returns from functions.
