0152  * PowerPC and S390 do not support creation of instruction breakpoints using the

0154  *
0155  * ARM requires explicit rounding down of the instruction pointer in Thumb mode,
0156  * and then requires the single-step to be handled explicitly in the overflow
0157  * handler to avoid stepping into the SIGIO handler and getting stuck on the
0158  * breakpointed instruction.
0159  *
0160  * Since arm64 has the same issue with arm for the single-step handling, this
0161  * case also gets stuck on the breakpointed instruction.
