- Add PTRACE_GET_DEBUGREG/PTRACE_SET_DEBUGREG. The definition is as follows: /* * Get or set a debug register. The first 16 are DABR registers and the * second 16 are IABR registers. */ #define PTRACE_GET_DEBUGREG 25 #define PTRACE_SET_DEBUGREG 26 DABR == data breakpoint and IABR = instruction breakpoint in IBM speak. We could split out the IABR into 2 more ptrace calls but I figured there was no need and 16 DABR registers should be more than enough (POWER4/POWER5 have one). - Add 2 new SIGTRAP si_codes: TRAP_HWBKPT and TRAP_BRANCH. I couldnt find any standards on either of these so I copied what ia64 is doing. Again this might be better placed in include/asm-generic/siginfo.h Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
