Indeed. Breakpoints are set using the "Z" and "z" packets to the GDB server so we don't even know which opcode gets used for the breakpoint instruction. My guess is when we use the "Z" and "z" packets, we don't have any saved breakpoint opcode in the breakpoint site info and this code won't do anything. Would be good to verify this.
