rin | Obsolete PT_STEP and friends, that have never been implemented.
PT_STEP was exposed to userland for NetBSD 1.6 to 9, and
PT_SETSTEP and PT_CLEARSTEP was for 8 to 9. Therefore, they cannot be
reused for other purposes.
PT_STEP was introduced to arm/ptrace.h rev 1.2:
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/arm/include/ptrace.h#rev1.2
This was for workaround against GDB, which assumes PT_STEP is 9 (even
today!!), if it is undefined. But, this should have been dealt with
differently...

rin | Fix confusions related to encoding of instructions.
For __ARMEB__ in BE8 mode, instructions are encoded in little-endian.
Therefore, we need to swap bytes against these in native byte order.
In other cases, i.e., __ARMEL__ and __ARMEB__ in BE32 mode, instructions
are in native byte order, and we don't need to swap them.

Introduce PTRACE_REG_FP() a helper macro to retrieve the frame pointer
The macro is dummy for ia64 (the FP register is unknown and can change
freely) and sparc/sparc64 (not stored in struct reg).

kamil | Define PTRACE_ILLEGAL_ASM for arm (32-bit)
udf $0 is expected to raise SIGILL for all ARM 32-bit targets.

PR/52867: Martin Husemann: arm sofware breakpoint asm is slightly off
ARM uses an undefined instruction to emulate a software breakpoint.
However, the ptrace.h instruction on the one hand, and gdb/the kernel
disagree on the exact value.
This causes PTRACE_BREAKPOINT_ASM to generate a SIGILL instead of a SIGTRAP.
|
| 1.11 |
| 12-Apr-2017 |
kamil | Add new macro PTRACE_BREAKPOINT_ASM in <sys/ptrace.h> MD part
This macro ships with a MD-specific assembly instruction triggering
a software breakpoint.
Missing instruction for powerpc targets.
This code is used in ATF tests (lib/libc/sys/t_ptrace_wait).
Original patch by Nick Hudson, thanks!

kamil | Add new ptrace(2) API: PT_SETSTEP & PT_CLEARSTEP
These operations allow to mark thread as a single-stepping one.
This allows to i.a.:
- single step and emit a signal (PT_SETSTEP & PT_CONTINUE)
- single step and trace syscall entry and exit (PT_SETSTEP & PT_SYSCALL)
The former is useful for debuggers like GDB or LLDB. The latter can be used
to singlestep a usermode kernel. These examples don't limit use-cases of
this interface.
Define PT_*STEP only for platforms defining PT_STEP.
Add new ATF tests setstep[1234].
These ptrace(2) operations first appeared in FreeBSD.

ARMFPE hasn't compiled since NetBSD 4. Remove it.
Complete support for FPU_VFP.
fpregs now contains vfpreg.
XXX vfpreg only has space for 16 64-bit FP registers though VFPv3 and later
have 32 64-bit FP registers.

Make sure that PT_STEP is defined for userland, even though we don't
support it in the kernel yet. If we don't do this, GDB arbitrarily
assumes we wanted it to be 9, which is silly.
In the kernel, leave it undefined so that sys_process.c doesn't
generate code for it.

Shared ARM ptrace(2) implementation. Mostly the same as the arm32
version, but with some #ifdefs for arm26.
Also, don't define PT_STEP, since we don't implement it. This should
reduce code size a little.
