target_pid_to_str on the wrong target stack. Most targets print a

The tests in gdb.base/advance-until-multiple-locations.exp that expect
the program to stop at a caller fail on some systems, depending on
compiler. E.g., with Clang 10, I see:
advance ovld_func
0x00000000004011a3 in test () at /home/pedro/gdb/binutils-gdb/src/gdb/testsuite/gdb.base/advance-until-multiple-locations.cc:51
51 ovld_func ();
(gdb) FAIL: gdb.base/advance-until-multiple-locations.exp: advance_overload: second advance stops at caller
And Tom de Vries saw:
...
(gdb) until ovld_func^M
main () at advance-until-multiple-locations.cc:61^M
61 }^M
(gdb) FAIL: gdb.base/advance-until-multiple-locations.exp:until_overload: until ovld_func
...
Which exact line the program stops is not important. All we care
about here is that the program stopped at the caller function.
So fix it by adjusting the patterns to match the frame header/function
reported by the breakpoint hits instead of the source lines text.

parse_args uses getopt_long_only so it can handle long options both
with double and single dash. But this means that some single dash
options like -gdwarf-1 don't generate an error (unlike --gdwarf-1).
This is especially confusing since there is also --gdwarf2, but no
--gdwarf4 (it is --gdwarf-4). When giving -gdwarf4 the option is
silently interpreted as -g (which set dwarf_version to 2). This causes
some confusion for people who don't expect this and suddenly get
DWARF2 instead of DWARF4 as they might expect.
So make it so that the -gdwarf<unknown> creates an error, just like
--gdwarf<unknown> would.
__{preinit,init,fini}_array_start symbols must be word aligned in
linker scripts. If the section preceding the __*_array_start symbol
has an odd size, then a NULL byte will be present between the start
symbol and the .*_array section itself, when the section gets
automatically word-aligned.
This results in a branch to an invalid address when the CRT startup
code tries to run through the functions listed in the array sections.
Some MSP430 linker scripts do not align the __*_array start symbols, so
this added warning will catch that problem and help the user avoid
the potential incorrect execution of the program.

Assertion `result.size () == 1 || canonical->pre_expanded' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
...
Fix this by detecting the error condition in decode_line_full instead, and
throwing an error, such that we have instead:
...
(gdb) b main:L1
Location main:L1 not available
(gdb)
...
Unfortunately, to call event_location_to_string, which is used to get the
location name in the error message, we need to pass a non-const struct
event_location, because the call may cache the string in the struct (See
EL_STRING). So, we change the prototype of decode_line_full accordingly, and
everywhere this propages to.

If you do "advance LINESPEC", and LINESPEC expands to more than one
location, GDB just errors out:
if (sals.size () != 1)
error (_("Couldn't get information on specified line."));
For example, advancing to a line in an inlined function, inlined three
times:
(gdb) b 21
Breakpoint 1 at 0x55555555516f: advance.cc:21. (3 locations)
(gdb) info breakpoints
Num Type Disp Enb Address What
1 breakpoint keep y <MULTIPLE>

1.3 y 0x000055555555518d in inline_func at advance.cc:21
(gdb) advance 21
Couldn't get information on specified line.
(gdb)
Similar issue with the "until" command, as it shares the
implementation with "advance".
Since, as the comment in gdb.base/advance.exp says, "advance <location>"
is really just syntactic sugar for "tbreak <location>;continue",
fix this by making GDB insert a breakpoint at all the resolved
locations.
A new testcase is included, which exercises both "advance" and
"until", in two different cases expanding to multiple locations:
- inlined functions
- C++ overloads
This also exercises the inline frames issue fixed by the previous
patch.

If you do "tbreak LINENO; c" to advance to an inlined function, GDB
presents the stop at the inline frame instead of at the non-artificial
stack frame:
(gdb) list 21
18 static inline __attribute__ ((always_inline)) int
19 inline_func (int i)
20 {
21 return i + 1;
22 }
(gdb) tbreak 21

(gdb) c
Continuing.
Temporary breakpoint 3, inline_func (i=0) at advance.cc:21
21 return i + 1;
The logic for this is in stopped_by_user_bp_inline_frame:
/* Loop over the stop chain and determine if execution stopped in an
inlined frame because of a breakpoint with a user-specified
location set at FRAME_BLOCK. */
static bool
stopped_by_user_bp_inline_frame (const block *frame_block, bpstat stop_chain)
If however, you do "advance LINENO" or "until LINENO" instead, GDB
presents the stop at the non-artificial frame:
(gdb) advance 21
main () at advance.cc:43
43 i = inline_func (i);
(gdb)
"advance" and "until" should really behave like user breakpoints here,
since their location is also user-specified. As the comment in
gdb.base/advance.exp says, "advance <location>" is really just
syntactic sugar for "tbreak <location>; continue".
Fix this by making stopped_by_user_bp_inline_frame also consider
advance/until breakpoints.

gdb_bfd_map_over_sections that took a gdb::function_view.

This commit follows on from the earlier commit "libctf, ld, binutils:
add textual error/warning reporting for libctf" and converts every error
in libctf that was reported using ctf_dprintf to use ctf_err_warn
instead, gettextizing them in the process, using N_() where necessary to
avoid doing gettext calls unless an error message is actually generated,
and rephrasing some error messages for ease of translation.
This requires a slight change in the ctf_errwarning_next API: this API
is public but has not been in a release yet, so can still change freely.
The problem is that many errors are emitted at open time (whether
opening of a CTF dict, or opening of a CTF archive): the former of these
throws away its incompletely-initialized ctf_file_t rather than return
it, and the latter has no ctf_file_t at all. So errors and warnings
emitted at open time cannot be stored in the ctf_file_t, and have to go
elsewhere.
We put them in a static local in ctf-subr.c (which is not very
thread-safe: a later commit will improve things here): ctf_err_warn with
a NULL fp adds to this list, and the public interface
ctf_errwarning_next with a NULL fp retrieves from it.
We need a slight exception from the usual iterator rules in this case:
with a NULL fp, there is nowhere to store the ECTF_NEXT_END "error"
which signifies the end of iteration, so we add a new err parameter to
ctf_errwarning_next which is used to report such iteration-related
errors. (If an fp is provided -- i.e., if not reporting open errors --
this is optional, but even if it's optional it's still an API change.
This is actually useful from a usability POV as well, since
ctf_errwarning_next is usually called when there's been an error, so
overwriting the error code with ECTF_NEXT_END is not very helpful!
So, unusually, ctf_errwarning_next now uses the passed fp for its
error code *only* if no errp pointer is passed in, and leaves it
untouched otherwise.)
ld, objdump and readelf are adapted to call ctf_errwarning_next with a
NULL fp to report open errors where appropriate.
The ctf_err_warn API also has to change, gaining a new error-number
parameter which is used to add the error message corresponding to that
error number into the debug stream when LIBCTF_DEBUG is enabled:
changing this API is easy at this point since we are already touching
all existing calls to gettextize them. We need this because the debug
stream should contain the errno's message, but the error reported in the
error/warning stream should *not*, because the caller will probably
report it themselves at failure time regardless, and reporting it in
every error message that leads up to it leads to a ridiculous chattering
on failure, which is likely to end up as ridiculous chattering on stderr
(trimmed a bit):
CTF error: `ld/testsuite/ld-ctf/A.c (0): lookup failure for type 3: flags 1: The parent CTF dictionary is unavailable'
CTF error: `ld/testsuite/ld-ctf/A.c (0): struct/union member type hashing error during type hashing for type 80000001, kind 6: The parent CTF dictionary is unavailable'
CTF error: `deduplicating link variable emission failed for ld/testsuite/ld-ctf/A.c: The parent CTF dictionary is unavailable'
ld/.libs/lt-ld-new: warning: CTF linking failed; output will have no CTF section: `The parent CTF dictionary is unavailable'
We only need to be told that the parent CTF dictionary is unavailable
*once*, not over and over again!
errmsgs are still emitted on warning generation, because warnings do not
usually lead to a failure propagated up to the caller and reported
there.
Debug-stream messages are not translated. If translation is turned on,
there will be a mixture of English and translated messages in the debug
stream, but rather that than burden the translators with debug-only
output.
