I know this has been delayed for too long. But I thought a small update would
perhaps help.
Looks like to get call-stack debug info, all we require to do is define
INCOMING_RETURN_ADDR_RTX. In AVR, since the return address is pushed onto the
stack for every call instruction, the above hook is defined to
avr_incoming_return_addr_rtx() of dwarf2out.c:
rtx
avr_incoming_return_addr_rtx(void) {
return gen_rtx_MEM (HImode, stack_pointer_rtx);
}
And this gives an ICE in dwarf2out_frame_debug_expr(). Modifying the above
function to pre decrement the stack pointer gives an ICE in
initial_return_save()
gen_rtx_MEM (HImode, gen_rtx_PRE_DEC (HImode, stack_pointer_rtx))

The reason for ICE is that POST_DEC is not handled in
dwarf2out_frame_debug_expr(). Fixing that issue will enable the compiler to
generate the call-stack debug info.

This is handled by properly defining INCOMING_FRAME_SP_OFFSET.
You don't need a POST_DEC in the INCOMING_RETURN_ADDR_RTX definition.
C.f. the i386 versions of these, which set up the exact same sort of
on-stack return address.

Going by the internals document, INCOMING_FRAME_SP_OFFSET is already defined
but it is not used anywhere (in my patch).
Looking at i386, I understand that the return address is stored on the stack
much in the same way. However, what I dont understand is the requirement for
cfa initialization in prologue expansion. This is something not handled in AVR.
> You don't need a POST_DEC in the INCOMING_RETURN_ADDR_RTX definition.
INCOMING_RETURN_ADDR_RTX per se is not using POST_DEC. But once they are
defined to some values, during the libgcc build, an ICE is hit in
dwarf2out_frame_debug_expr(). If POST_DEC mode is defined, ICE disappears. I am
yet to understand the relation between the POST_DEC and ICE and why it appears
when only CFI is being emitted.
Attaching the patch.

Certainly it's going to be used by the generic code in dwarf2out_frame_init,
and if that's wrong everything that follows will be off as well.

Ah, I see. Nothing to do with the initial frame setup, but the rest of the
unwind info, since AVR uses POST_DEC for pushes.
See
http://gcc.gnu.org/ml/gcc-patches/2011-02/msg01059.html
for my proposed patch for this. Note that the message contains both gas
and gcc patches.

I tried gcc 4.3.2 from the WinAVR distribution and also avr-gcc 4.4.1.
The short story is: There is call frame information there, but not enough.
Specifically, the Call Frame instructions to reconstruct the pc to unwind rule
table are still missing, but the CIE and FDE are present.
I compared gcc and avr-gcc output on linux with the following results:
gcc:

Hi Torleif,
Please check more recent versions such as 4.3.2, 4.3.3, or 4.4.0. There are
.debug_frame sections in there, but I don't know if it contains the information
that you're looking for.
Thanks,

------- Additional Comments From bjoern dot m dot haase at web dot de 2005-05-06 13:59 -------
Hi,
I have been reviewing PR19885 and come to the following conclusions:
1.) As expected, Torleif is right: I can confirm that the problem exists,
2.) it should, however, probably be called rather a request for enhancement
than a bug: Beside call stack information the debugging info should be ok in
principle.
3.) There seems to be only one little part missing in order to add the call
stack information as well: The back-end needs to provide the information at
which memory address the debugger could localize the return address. This would
require to implement the target hook INCOMING_RETURN_ADDR_RTX and use the
RTX_FRAME_RELATED_P predicate for all of the prologue/epilogue insn.
I think the best way to address this issue would be to resolve this issue
simultaneously when switching from asm-prologue/epilogue to
RTL-prologue/epilogue. Since Andy Hutchinson is just working on this issue, we
might soon have a solution. Hopefully :-). Would be very helpfull to have call
stack info in avrstudio.
Yours,
Bjoern
P.S.:
I hope you will not be flaming me for adding you on the CC list. :-) Just
thought that you might be interrested since I know you are working on the
prologue/epilogue issue.
