The 'Programming Environments Manual for 32-Bit Implementations of the PowerPC™ Architecture' says: The following are not traced: • rfi instruction • sc and trap instructions that trap • Other instructions that cause interrupts (other than trace interrupts) • The first instruction of any interrupt handler • Instructions that are emulated by software So I think PPC32 should return -1 as well.
