In gdb.trace/tfile.exp, we execute binary to generate tracefile,
remote_exec target "$binfile"
however, this fails on bare metal target. This patch is to
handle binary execution failure by running binary in GDB.
The binary will do some io operation to generate tracefile, so
we need a check 'target_info exists gdb,nofileio'.
This patch is to check whether tracefile is generated. tfile.exp can
be skipped if generation is failed, while test_tfind_tfile in
mi-traceframe-changed.exp is skipped if generated failed. The rest of
the mi-traceframe-changed.exp can still be executed, because on some
bare metal targets, the remote stub supports tracepoint but doesn't
support fileio.

Functions ctf_fetch_registers and tfile_fetch_registers have some
duplicated code about guessing the PC in regcache. Sometimes, we
may change one function and forget to update the other one, like this
https://www.sourceware.org/ml/gdb-patches/2014-01/msg00292.html

[PATCH 2/2] Create inferior for ctf target.

In ctf trace, for each 'R' block, we save it as a "register" event,
as defined below in metadata.
event {
name = "register";
id = 0;
fields := struct {
ascii contents[440];
};
}
Nowadays, we initialize trace_regblock_size by getting the length of
"contents" from a "register" event. However, 'R' block may not exist
in traceframe, as a result, "register" event doesn't exist in trace file
and trace_regblock_size isn't set.
This patch changes to get trace_regblock_size from metadata (or declaration)
which always exists.

This PR is about an assertion failure in GDB that can be triggered by
setting "backtrace limit" to a value that causes GDB to stop unwinding
after an inline frame. In this case, an assertion in
inline_frame_this_id will trigger:
/* We need a valid frame ID, so we need to be based on a valid
frame. (...). */
gdb_assert (frame_id_p (*this_id));
Looking at the function:
static void
inline_frame_this_id (struct frame_info *this_frame,
void **this_cache,
struct frame_id *this_id)
{
struct symbol *func;
/* In order to have a stable frame ID for a given inline function,
we must get the stack / special addresses from the underlying
real frame's this_id method. So we must call get_prev_frame.
Because we are inlined into some function, there must be previous
frames, so this is safe - as long as we're careful not to
create any cycles. */
*this_id = get_frame_id (get_prev_frame (this_frame));
we see we're computing the frame id for the inline frame. If this is
an inline frame, which is a virtual frame constructed based on debug
info, on top of a real stack frame, we should _always_ be able to find
where the frame was inlined into, as that ultimately just means
peeling off the virtual frames on top of the real stack frame. If
there ultimately was no prev (real) stack frame, then we wouldn't have
been able to construct the inline frame either, by design. That's
what the assertion catches.
So we have an inline frame, we should _always_ be able to compute its
ID, even if that means bypassing the user backtrace limits to get at
the real stack frame's info. The problem is that inline_frame_id
calls get_prev_frame, and that takes user backtrace limits into
account. Code that wants to bypass the limits calls get_prev_frame_1
instead.
Note how get_prev_frame_1 already skips all checks for inline frames:
/* If we are unwinding from an inline frame, all of the below tests
were already performed when we unwound from the next non-inline
frame. We must skip them, since we can not get THIS_FRAME's ID
until we have unwound all the way down to the previous non-inline
frame. */
if (get_frame_type (this_frame) == INLINE_FRAME)
return get_prev_frame_if_no_cycle (this_frame);
And note how the related frame_unwind_caller_id function also uses
get_prev_frame_1:
struct frame_id
frame_unwind_caller_id (struct frame_info *next_frame)
{
struct frame_info *this_frame;
/* Use get_prev_frame_1, and not get_prev_frame. The latter will truncate
the frame chain, leading to this function unintentionally
returning a null_frame_id (e.g., when a caller requests the frame
ID of "main()"s caller. */
next_frame = skip_artificial_frames (next_frame);
this_frame = get_prev_frame_1 (next_frame);
if (this_frame)
return get_frame_id (skip_artificial_frames (this_frame));
else
return null_frame_id;
}
get_prev_frame_1 is currently static in frame.c. As a _1 suffix is
not a good name for an extern function, I've renamed it.

This patch enables use of DWARF unwinders for the SPU target.
In addition to appending the DWARF unwinders, we also need to install
a spu_dwarf_reg_to_regnum that maps the raw stack pointer register to
the cooked version (to avoid mismatches with gdbarch_sp_regnum).
This also causes confusion with the AX collect handling, so we also
install ax_pseudo_register routines to handle the cooked SP.

This patch fixes a problem that prevented use of the Dwarf unwinders on SPU,
because dwarf2-frame.c common code did not support the situation where the
stack and/or frame pointer is maintained in a *vector* register. This is
because read_addr_from_reg is hard-coded to assume that such pointers can
be read from registers via a simple get_frame_register / unpack_pointer
operation.
Now, there *is* a routine address_from_register that calls into the
appropriate tdep routines to handle pointer values in "weird" registers
like on SPU, but it turns out I cannot simply change dwarf2-frame.c to
use address_from_register. This is because address_from_register uses
value_from_register to create a (temporary) value, and that routine
at some point calls get_frame_id in order to set up that value's
VALUE_FRAME_ID entry.
However, the dwarf2-frame.c read_addr_from_reg routine will be called
during early unwinding (to unwind the frame's CFA), at which point the
frame's ID is not actually known yet! This would cause an assert.
On the other hand, we may notice that VALUE_FRAME_ID is only needed in the
value returned by value_from_register if that value is later used as an
lvalue. But this is obviously never done to the temporary value used in
address_from_register. So, if we could change address_from_register to
not call value_from_register but instead accept constructing a value
that doesn't have VALUE_FRAME_ID set, things should be fine.
To do that, we can change the value_from_register callback to accept
a FRAME_ID instead of a FRAME; the only existing uses of the FRAME
argument were either to extract its frame ID, or its gdbarch. (To
keep a way of getting at the latter, we also change the callback's
type from "f" to "m".) Together with the required follow-on changes
in the existing value_from_register implementations (including the
default one), this seems to fix the problem.
As another minor interface cleanup, I've removed the explicit TYPE
argument from address_from_register. This routine really always
uses a default pointer type, and in the new implementation it -to
some extent- relies on that fact, in that it will now no longer
handle types that require gdbarch_convert_register_p handling.

Hi,
We find gdb.base/printcmds.exp fails a lot on windows host, like this,
p ctable1[163]
$204 = 163 '£'
(gdb) FAIL: gdb.base/printcmds.exp: p ctable1[163]
however, on linux host,
p ctable1[163]
$205 = 163 '\243'
(gdb) PASS: gdb.base/printcmds.exp: p ctable1[163]
The printing related code is in valprint.c:print_wchar,
if (gdb_iswprint (w) && (!need_escape || (!gdb_iswdigit (w)
&& w != LCST ('8')
&& w != LCST ('9'))))
{
gdb_wchar_t wchar = w;
if (w == gdb_btowc (quoter) || w == LCST ('\\'))
obstack_grow_wstr (output, LCST ("\\"));
obstack_grow (output, &wchar, sizeof (gdb_wchar_t));
}
else
{
// print W in hex or octal digits
}
When I debug gdb on different hosts, I find
on windows host, gdb_iswprint (iswprint) returns true if 'w' is 163.
However, on linux host, iswprint returns false if 'w' is 163. Looks
this difference is caused by the charset. On Linux host,
the target-charset is ANSI_X3.4-1968, while on windows host, the
target-charset is CP1252.
We can see how target-charset affects the output. On linux host,
(gdb) set target-charset ASCII
(gdb) p ctable1[163]
$1 = 163 '\243'
(gdb) set target-charset CP1252
(gdb) p ctable1[163]
$2 = 163 '£'
we can print the pound sign too, and it shows target-charset does
affect the output.
This patch is to set target-charset temporarily to ASCII for some
charset-sensitive tests. Tested on arm-none-eabi and
powerpc-linux-gnu on mingw32 host. More than one hundred fails are
fixed.
