add target method delegation
This patch replaces some code in the record targets with target method
delegation.
record-full.c stores pointers to many target methods when the record
target is pushed. Then it later delegates some calls via these. This
is wrong because it violates the target stack contract. In particular
it is ok to unpush a target at any stratum, but record-full does not
keep track of this, so it could potentially call into an unpushed
target.
This patch fixes the problem by using the newly-introduced generic
approach to target delegation for the methods in question.

Revise signal mapping function in GDB interface for RX sim.
sim/rx/gdb-if.c had a function named `rx_signal_to_host'. This
function mapped signal numbers used by the BSP to host signal
numbers which, at one time a while back, were used by GDB
as target signal numbers. This change updates the signal
numbers returned to be those names prefixed with "GDB_SIGNAL_"
as defined in include/gdb/signals.h.
It also changes the name of the function somewhat to better
match what the function currently does. I noticed that this
function is not static - and there's no reason for it not
to be - so I made it static too.

sim: delete duplicate SIGINT handling
Many of the simulators change the SIGINT handler.
E.g., moxie/interp.c:
sigsave = signal (SIGINT, interrupt);
However, this is unnecessary.
remote-sim.h already provides an API for asynchronously stopping
a sim; and both gdb and the drivers (run.c and nrun.c at least,
I didn't check the others) install a SIGINT handler which
calls this method.

Fix "ERROR: no fileid for" in the testsuite.
If GDB has crashed then gdb_spawn_id still exists (although it does not work).
So my patch does not change anything. And also currently it will leave the
stale gdbserver running anyway.
In general if gdb_spawn_id does not exist then send_gdb + gdb_expect just do
not make sense anyway. So this patch just prevents the error in such case.
The killing of stale gdbserver could be improved multiple ways (also as
suggested by Pedro in the original thread) but that is IMO outside of the
scope of this patch. Apparently if there is no good response from GDB then
gdb_finish() should try to call gdb_start just to kill that gdbserver, IIUC.

Explicitly mark vtables as code space
Ports for Hardvard architectures will typically have in their
pointer_to_address hook a check for TYPE_CODE_SPACE in their
"pointer_to_address" gdbarch method. E.g., rl78's:
/* Is it a code address? */
if (TYPE_CODE (TYPE_TARGET_TYPE (type)) == TYPE_CODE_FUNC
|| TYPE_CODE (TYPE_TARGET_TYPE (type)) == TYPE_CODE_METHOD
|| TYPE_CODE_SPACE (TYPE_TARGET_TYPE (type))
|| TYPE_LENGTH (type) == 4)
return rl78_make_instruction_address (addr);
else
return rl78_make_data_address (addr);
The avr port is similar.
The vtable type is a struct type gdb itself bakes. Being neither a
function, nor a method, and absent explicit flagging as residing in
code space, ends up being considered data.
This patch marks the type as code when it is created, on the theory
that this is needed for all Hardvard architectures. I believe this
should make no difference on archs with flat address space. Testing
on x86-64 GNU/Linux shows no changes.

Note that the difference between these are the warnings regarding
linker symbols. Aside from the warnings, the result is the same.
I.e. gdb produces the correct answer despite the warnings. The
reason for the other 8 failures is the same: the test harness is not
expecting these warnings.
I spent some time (a while ago) looking at the reason for these
warnings. As I recall, we are now getting further along in the type
resolution process than we were without my patch. I.e. for the
example above, the code in question never got to the point where it
was looking for the specified linker symbol. So it seems to me that,
at worst, my patch exposes some other problem, but is not directly the
cause of the problem.

H8/300: Fix gdb<->sim register mapping.
Currently, printing the H8/300 ccr register when debugging with the

Breakpoint 1, foo (i=0x0 <foo>) at main.c:4

(gdb) info registers ccr
Register 13 is not available
'13' is the ccr pseudo-register. This pseudo-register provides an
8-bit view into the raw ccr register (regno=8).
The problem is that the H8/300 port does not define a
register_sim_regno gdbarch hook, and thus when fetching the raw
register off of the sim, we end up in legacy_register_sim_regno trying
to figure out the sim register number for the raw CCR register:
int
legacy_register_sim_regno (struct gdbarch *gdbarch, int regnum)
{
/* Only makes sense to supply raw registers. */
gdb_assert (regnum >= 0 && regnum < gdbarch_num_regs (gdbarch));
/* NOTE: cagney/2002-05-13: The old code did it this way and it is
suspected that some GDB/SIM combinations may rely on this
behavour. The default should be one2one_register_sim_regno
(below). */
if (gdbarch_register_name (gdbarch, regnum) != NULL
&& gdbarch_register_name (gdbarch, regnum)[0] != '\0')
return regnum;
else
return LEGACY_SIM_REGNO_IGNORE;
}
Because the raw ccr register does not have a name (so that it is
hidden from the user), that returns LEGACY_SIM_REGNO_IGNORE. That
means that we never actually read the value of the raw ccr register.
Before the <unavailable> support, this must have meant that ccr was
_always_ read as 0... At least, I'm not seeing how this ever worked.
The fix for that is adding a gdbarch_register_sim_regno hook that maps
all raw registers. Looking at sim/h8300/sim-main.h, I believe the
sim's register numbers are compatible with gdb's, so no actual
convertion is necessary.

Fix readelf so it doesn't complain about corrupt attribute.
When a DW_FORM_flag_present attribute comes at the very end of a

because it's checking to make sure there's at least one byte of

Return target_xfer_status in to_xfer_partial
This patch does the conversion of to_xfer_partial from
LONGEST (*to_xfer_partial) (struct target_ops *ops,
enum target_object object, const char *annex,
gdb_byte *readbuf, const gdb_byte *writebuf,
ULONGEST offset, ULONGEST len);
to
enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops,
enum target_object object, const char *annex,
gdb_byte *readbuf, const gdb_byte *writebuf,
ULONGEST offset, ULONGEST len, ULONGEST *xfered_len);
It changes to_xfer_partial return the transfer status and the transfered
length by *XFERED_LEN. Generally, the return status has three stats,
- TARGET_XFER_OK,
- TARGET_XFER_EOF,
- TARGET_XFER_E_XXXX,
See the comments to them in 'enum target_xfer_status'. Note that
Pedro suggested not name TARGET_XFER_DONE, as it is confusing,
compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF.
With this change, GDB core can handle unavailable data in a convenient
way.
The rationale behind this change was mentioned here
https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html
Consider an object/value like this:
0 100 150 200 512
DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III
where D is valid data, and xxx is unavailable data, and I is beyond
the end of the object (Invalid). Currently, if we start the
xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes.
The xfer machinery then retries fetching [100,512), and gets back
TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either
interested in either having the whole of the 512 bytes available,
or erroring out. But, in this scenario, we're interested in
the data at [150,512). The problem is that the last
TARGET_XFER_E_UNAVAILABLE gives us no indication where to
start the read next. We'd need something like:
get me [0,512) >>>
<<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK
get me [100,512) >>> (**1)
<<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE.
get me [150,512) >>>
<<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK.
get me [200,512) >>>
<<< no more data, return TARGET_XFER_EOF.
This naturally implies pushing down the decision of whether
to return TARGET_XFER_E_UNAVAILABLE or something else
down to the target. (Which kinds of leads back to tfile
itself reading from RO memory from file (though we could
export a function in exec.c for that that tfile delegates to,
instead of re-adding the old code).
Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to
check whether a status is an error or not, to stop using "status < 0".
This patch also eliminates the comparison between status and 0.
No target implementations to to_xfer_partial adapts this new
interface. The interface still behaves as before.

gdb/elfread.c: Enable ifunc support on ARM.
There are two failures in the gnu-ifunc.exp test on ARM. These are
due to the failure to resolve the correct target function when
attempting to breakpoint a GNU ifunc resolved function:
(gdb) break gnu_ifunc
Breakpoint 4 at gnu-indirect-function resolver at 0x2aacb5a2
when gnu_ifunc has been resolved this should actually be:
(gdb) break gnu_ifunc
Breakpoint 4 at 0x868c
There are two reasons for this. The first is that ARM does not have a
separate .got.plt section so looking this up will always fail. The second
is that the Thumb bit needs to be stripped from the address to allow
it to be reliably compared when inserting into the ifunc cache.
Tested with no regressions on arm-linux-gnueabihf and
