Indeed, x86 hardware breakpoints are way more powerful and don't require changing instructions. Only problem there's just 4 of them, but it's usually enough. It's nice to be able to set a breakpoint on data access as well, it's often more useful than on instructions. https://en.wikipedia.org/wiki/X86_debug_register https://en.wikipedia.org/wiki/X86_debug_register
