88c32e64e8SGuo Ren	  For abiv2 we couldn't use "trap 1" as user space bkpt in gdbserver, because
89c32e64e8SGuo Ren	  abiv2 is 16/32bit instruction set and "trap 1" is 32bit.
90c32e64e8SGuo Ren	  So we need a 16bit instruction as user space bkpt, and it will cause an illegal
91c32e64e8SGuo Ren	  instruction exception.
92c32e64e8SGuo Ren	  In kernel we parse the *regs->pc to determine whether to send SIGTRAP or not.
