Workaround patch for GCC
This patch for GCC forces the old debug format. With it I don't have the
backtrace problems:

I looked at the ELF with readelf a bit but nothing
stood out as obviously wrong.
I think it would be worthwhile to track down where
gdb is misinterpreting the data. That gcc patch
definitely should not be needed; and I would have
thought gdb 7.6 would have all the needed DWARF 4 updates.

--- Comment #3 from Sebastian Huber <sebastian.huber@embedded-brains.de> ---
With Binutils 2.24.51.20140322, GCC 4.9.0 20140323, and GDB 7.7.50.20140322-cvs
I still have the problem.
An objdump with --dwarf --dwarf-check gives:
sparc-rtems4.11-objdump --dwarf --dwarf-check ticker.exe >/dev/null
sparc-rtems4.11-objdump: Warning: There is an overlap [0x668 - 0x650] in
.debug_ranges section.
sparc-rtems4.11-objdump: Warning: There is an overlap [0x6c0 - 0x6a8] in

Is this a problem? I am not sure how to begin to search for the problem. Is
this more likely a Binutils, GCC or GDB problem?
On another test program with C++ I get even more warnings:

There exists a patch for this problem:
https://www.sourceware.org/ml/gdb-patches/2014-07/msg00012.html
It was not applied due to a problem with the StackGhost. On Linux you don't
observe these problems since here you have a special case in sparc-linux-tdep.c
to add the DWARF unwinder. As a user I think it is quite unsatisfactory that
GDB is broken on SPARC for all non-Linux systems with GCC 4.8 and above due to
a problem in the StackGhost.

commit 14aba1ac0d583ebd77b7645f88308d75c0a69d0f
Author: Joel Brobecker <brobecker@adacore.com>
Date: Fri Nov 21 04:59:35 2014 +0100
Lift DWARF unwinder restriction in dwarf2-frame.c::dwarf2_frame_cfa
GDB is currently broken on all SPARC targets when using GCC 4.9.
When trying to print any local variable:
(gdb) p x
can't compute CFA for this frame
This is related to the fact that the compiler now generates DWARF 4
debugging info by default, and in particular that it now emits
DW_OP_call_frame_cfa, which triggers a limitation in dwarf2_frame_cfa:
/* This restriction could be lifted if other unwinders are known to
compute the frame base in a way compatible with the DWARF
unwinder. */
if (!frame_unwinder_is (this_frame, &dwarf2_frame_unwind)
&& !frame_unwinder_is (this_frame, &dwarf2_tailcall_frame_unwind))
error (_("can't compute CFA for this frame"));
We couldn't append the dwarf2 unwinder to all SPARC targets because
it does not work properly with StackGhost:
https://www.sourceware.org/ml/gdb-patches/2014-07/msg00012.html
We also later discovered that using the DWARF2 unwinder means
using it for computing the function's return address, which
is buggy when it comes to functions returning a struct (where
the return address is saved-pc+12 instead of saved-pc+8).
This is because GCC is emitting the info about the return address
as %o7/%i7 instead of the actual return address. For functions
that have debugging info, we compensate by looking at the function's
return type and add the extra +4, but for function without debug
info, we're stuck.
EricB and I twisted the issue in all the directions we could think of,
and unfortunately couldn't find a way to make it work without
introduction one regression or another.
But, stepping back a little, just removing the restriction seems to work
well for us on all both sparc-elf and {sparc,sparc64}-solaris.
After reviewing the previous discussions about this test, I could
not figure out whether some unwinders were already known to have
incompatible CFAs or if the concern was purely theoretical:
https://www.sourceware.org/ml/gdb-patches/2009-06/msg00191.html
https://www.sourceware.org/ml/gdb-patches/2009-07/msg00570.html
https://www.sourceware.org/ml/gdb-patches/2009-09/msg00027.html
At the moment, we took the approach of trying it out, and see what
happens...
gdb/ChangeLog:
PR backtrace/16215:
* dwarf2-frame.c (dwarf2_frame_cfa): Remove the restriction
the frame unwinder must either be the dwarf2_frame_unwind
or the dwarf2_tailcall_frame_unwind. Verify that this_frame's
stack_addr is valid before calling get_frame_base. Throw
an error if not valid.
Tested on sparc-solaris and sparc-elf with AdaCore's testsuite
(the FSF testsuite crashes all of AdaCore's solaris machines).

Lift DWARF unwinder restriction in dwarf2-frame.c::dwarf2_frame_cfa
GDB is currently broken on all SPARC targets when using GCC 4.9.
When trying to print any local variable:
(gdb) p x
can't compute CFA for this frame
This is related to the fact that the compiler now generates DWARF 4
debugging info by default, and in particular that it now emits
DW_OP_call_frame_cfa, which triggers a limitation in dwarf2_frame_cfa:
/* This restriction could be lifted if other unwinders are known to
compute the frame base in a way compatible with the DWARF
unwinder. */
if (!frame_unwinder_is (this_frame, &dwarf2_frame_unwind)
&& !frame_unwinder_is (this_frame, &dwarf2_tailcall_frame_unwind))
error (_("can't compute CFA for this frame"));
We couldn't append the dwarf2 unwinder to all SPARC targets because
it does not work properly with StackGhost:
https://www.sourceware.org/ml/gdb-patches/2014-07/msg00012.html
We also later discovered that using the DWARF2 unwinder means
using it for computing the function's return address, which
is buggy when it comes to functions returning a struct (where
the return address is saved-pc+12 instead of saved-pc+8).
This is because GCC is emitting the info about the return address
as %o7/%i7 instead of the actual return address. For functions
that have debugging info, we compensate by looking at the function's
return type and add the extra +4, but for function without debug
info, we're stuck.
EricB and I twisted the issue in all the directions we could think of,
and unfortunately couldn't find a way to make it work without
introduction one regression or another.
But, stepping back a little, just removing the restriction seems to work
well for us on all both sparc-elf and {sparc,sparc64}-solaris.
After reviewing the previous discussions about this test, I could
not figure out whether some unwinders were already known to have
incompatible CFAs or if the concern was purely theoretical:
https://www.sourceware.org/ml/gdb-patches/2009-06/msg00191.html
https://www.sourceware.org/ml/gdb-patches/2009-07/msg00570.html
https://www.sourceware.org/ml/gdb-patches/2009-09/msg00027.html
At the moment, we took the approach of trying it out, and see what
happens...
gdb/ChangeLog:
PR backtrace/16215:
* dwarf2-frame.c (dwarf2_frame_cfa): Remove the restriction
the frame unwinder must either be the dwarf2_frame_unwind
or the dwarf2_tailcall_frame_unwind. Verify that this_frame's
stack_addr is valid before calling get_frame_base. Throw
an error if not valid.
Tested on sparc-solaris and sparc-elf with AdaCore's testsuite
(the FSF testsuite crashes all of AdaCore's solaris machines).
