a destination for the return address. If we have a register that
serves as the stack pointer, arrange for it to be filled with the
call frame address (CFA). The other registers are marked as
unspecified.
We copy the return address to the program counter, since many
parts in GDB assume that it is possible to get the return address
by unwinding the program counter register. However, on ISA's
with a dedicated return address register, the CFI usually only
contains information to unwind that return address register.
The reason we're treating the stack pointer special here is
because in many cases GCC doesn't emit CFI for the stack pointer
and implicitly assumes that it is equal to the CFA. This makes
some sense since the DWARF specification (version 3, draft 8,
p. 102) says that:
"Typically, the CFA is defined to be the value of the stack
pointer at the call site in the previous frame (which may be
different from its value on entry to the current frame)."
However, this isn't true for all platforms supported by GCC
(e.g. IBM S/390 and zSeries). Those architectures should provide
their own architecture-specific initialization function. */

/* Unwind the PC.
Note that if the next frame is never supposed to return (i.e. a call
to abort), the compiler might optimize away the instruction at
its return address. As a result the return address will
point at some random instruction, and the CFI for that
instruction is probably worthless to us. GCC's unwinder solves
this problem by substracting 1 from the return address to get an
address in the middle of a presumed call instruction (or the
instruction in the associated delay slot). This should only be
done for "normal" frames and not for resume-type frames (signal
handlers, sentinel frames, dummy frames). The function
get_frame_address_in_block does just this. It's not clear how
reliable the method is though; there is the potential for the
register state pre-call being different to that on return. */

DWARF frame unwinder executes one too many rows The problem is trying to unwind from a function where %ebp is NOT used as the frame pointer, and the size of the frame changes over the lifetime of that function. For instance, trying to unwind past the GNAT runtime function called system.tasking.rendezvous.timed_selective_wait on x86-linux, one can get: (gdb) bt [...] #3 0x0805364b in system.tasking.rendezvous.timed_selective_wait () #4 0xb7fe5068 in ?? () Backtrace stopped: previous frame inner to this frame (corrupt stack?) Looking at the CFI, we find the following initial instructions... > DW_CFA_def_cfa: %esp+4 (r4 ofs 4) > DW_CFA_offset: %eip at cfa-4 (r8 = %eip) ... and the associated FDE: > 00001be4 00000054 00001be8 FDE cie=00000000 pc=08053310..08053951 [...] > DW_CFA_advance_loc: 8 to 080534ad > DW_CFA_def_cfa_offset: 112 > DW_CFA_advance_loc2: 414 to 0805364b > DW_CFA_def_cfa_offset: 108 [...] The problem is that the DWARF frame unwinder executed the FDE until the row for PC == 0x0805364b. But in reality, our program hasn't executed the instruction at that address yet (it is the return address). So GDB executed a little too much of the FDE, giving us the wrong offset for the frame base, and thus the wrong address where %eip got saved. This patch fixes the problem by using a more correct PC as the bound for executing the FDE. gdb/ChangeLog: * dwarf2-frame.c (dwarf2_frame_cache): Use get_frame_address_in_block instead of get_frame_pc as the bound for executing the frame's FDE. gdb/testsuite/ChangeLog: * gdb.ada/rdv_wait: New testcase.

/* Pointer encoding helper functions. */
/* GCC supports exception handling based on DWARF2 CFI. However, for
technical reasons, it encodes addresses in its FDE's in a different
way. Several "pointer encodings" are supported. The encoding
that's used for a particular FDE is determined by the 'R'
augmentation in the associated CIE. The argument of this
augmentation is a single byte.
The address can be encoded as 2 bytes, 4 bytes, 8 bytes, or as a
LEB128. This is encoded in bits 0, 1 and 2. Bit 3 encodes whether
the address is signed or unsigned. Bits 4, 5 and 6 encode how the
address should be interpreted (absolute, relative to the current
position in the FDE, ...). Bit 7, indicates that the address
should be dereferenced. */

alignment at all in the frame unwind sections. Testing for
alignment before trying to interpret data would be incorrect.
However, GCC traditionally arranged for frame sections to be
sized such that the FDE length and CIE fields happen to be
aligned (in theory, for performance). This, unfortunately,
was done with .align directives, which had the side effect of
forcing the section to be aligned by the linker.
This becomes a problem when you have some other producer that
creates frame sections that are not as strictly aligned. That
produces a hole in the frame info that gets filled by the
linker with zeros.
The GCC behaviour is arguably a bug, but it's effectively now
part of the ABI, so we're now stuck with it, at least at the
object file level. A smart linker may decide, in the process
of compressing duplicate CIE information, that it can rewrite
the entire output section without this extra padding. */
