439dcbedba Special epilogue for vararg functions. We cannot do a pop to pc because 
there follows a sp increment for the va register save region. Instead issue
a separate pop to another register, increment sp, and then return:
        pop {r4, r5, r6, r7}
        pop {r3}
        add sp, #3 * 4
        bx r3

765de99fac Handle an interesting corner case: the constpool_entry being reference is two 
instructions away, i.e. its address is equal to PC.

aa6f0f3b3b Added O_F32 and O_64 in addition to UO_F32 and UO_64 even though by
