gdb: completion-support.exp: improve leading whitespace support
There is a expect support library in the source tree designed to help
developers test the auto-completion capabilities of GDB.
One of the functions is test_gdb_complete_unique_re. It is used
(usually indirectly via test_gdb_complete_unique) to test that a given
input line is completed as a given output line. The test checks for two
ways to do the completion: using tab-completion, or using the
'complete' command. To do this, calls to two dedicated functions are
performed. If we omit few details, we can consider that a call to
test_gdb_complete_unique $input $expected
is equivalent to the two following calls:
test_gdb_complete_tab_unique $input $expected
test_gdb_complete_cmd_unique $input $expected
When using the tab-completion, everything works as expected, but some
care must be taken when using the 'complete' command if the given input
has leading whitespaces. In such situation, the output of the
'complete' command will drop the leading whitespaces.
The current approach is that in such situation, the input and expected
outputs are right trimmed (i.e. all leading whitespaces are removed)
when performing the command completion check.
This means that the following call:
test_gdb_complete_unique " $input" " $expected"
is almost equivalent to (again, omitting few details and arguments):
test_gdb_complete_tab_unique " $input" " $expected"
test_gdb_complete_cmd_unique "$input" "$expected"
This approach comes with a problem that we encounter when running the
tests in complete-empty.exp. When doing so, we have:
Running .../gdb/testsuite/gdb.base/complete-empty.exp ...
DUPLICATE: gdb.base/complete-empty.exp: empty-input-line: cmd complete ""
This is because the test file does something like:
test_gdb_complete_unique "" "!" " " 1
test_gdb_complete_unique " " " !" " " 1¬
which, if we do the substitution introduced above is equivalent to:
test_gdb_complete_tab_unique "" "!"
test_gdb_complete_cmd_unique "" "!"
test_gdb_complete_tab_unique " " " !"
test_gdb_complete_cmd_unique "" "!"
We see that the lines 2 and 4 are now the same, and for this reason the
testing framework complains about DUPLICATE test names.
To fix that, this commit proposes that instead of left trimming both
input and expected outputs, only the expected output is trimmed.
Care must be taken in the case the completion gives more possibilities
than allowed by the max-completions setting. In this case, the input
will be repeated in the output in its left trimmed version. This commit
also ensures that this is taken care of.
With this commit, the gdb.base/complete-empty.exp still passes all its
tests but does not report the DUPLICATE anymore.

gdb/doc: shorten some source lines, and prevent some line breaks
Building on the previous commit, this makes use of a trailing @ to

I have also wrapped keyword and argument name pairs in @w{...} to

done this for the longer @deffn lines, where a line break is
possible. This makes the @deffn lines much nicer to read in the

gdb/doc: Remove (...) around guile procedure names in @deffn lines
Most guile procedures in the guile.texi file are defined like:
@deffn {Scheme Procedure} name arg1 arg2 arg3
But there are two places where we do this:
@deffn {Scheme Procedure} (name arg1 arg2 arg3)
Notice the added (...). Though this does represent how a procedure
call is written in scheme, it's not the normal style throughout the
manual. I also checked the 'info guile' info page to see how they
wrote there declarations, and they use the first style too.
The second style also has the drawback that index entries are added as
'(name', and so they are grouped in the '(' section of the index,
which is not very user friendly.
In this commit I've changed the definitions of make-command and
make-parameter to use the first style.
The procedure declaration lines can get pretty long with all of the
arguments, and this was true for both of the procedures I am changing
in this commit. I have made use of a trailing '@' to split the deffn
lines, and keep them under 80 characters in the texi source. This
makes no difference to how the final document looks.
Finally, our current style for keyword arguments, appears to be:
[#:keyword-name argument-name]
I don't really understand the reason for this, 'info guile' just seems
to use:
[#:keyword-name]
which seems just as good to me. But I don't propose to change
that just now. What I do notice though, is that sometimes, texinfo
will place a line break between the keyword-name and the
argument-name, for example, the pdf of make-command is:
make-command name [#:invoke invoke] [#:command-class
command-class] [#:completer-class completer] [#:prefix? prefix] [#:doc
doc-string]
Notice the line break after '#:command-class' and after '#:doc',
neither of which are ideal. And so, for the two commands I am
changing in this commit, I have made use of @w{...} to prevent line
breaks between the keyword-name and the argument-name. Now the pdf
looks like this:
make-command name [#:invoke invoke]
[#:command-class command-class] [#:completer-class completer]
[#:prefix? prefix] [#:doc doc-string]
Which seems much better. I'll probably update the other deffn lines
at some point.

gdb: make use add_setshow_prefix_cmd in gnu-nat.c
In gnu-nat.c we currently implement some set/show prefix commands
"manually", that is, we call add_prefix_cmd, and assign a set and show
function to each prefix command.
These set/show functions print an error indicating that the user
didn't type a complete command.
If we instead switch to using add_setshow_prefix_cmd then we can
delete the set/show functions, GDB provides some default functions,
which give a nice help style summary that lists all of the available
sub-commands, along with a one line summary of what each does.
Though this clearly changes the existing behaviour, I think this
change is acceptable as the new behaviour is more inline with other
set/show prefix commands, and the new behaviour is more informative.

could be removed. Then, I added a couple of missing bounds checks.
I believe this also fixes a possible bug with a missing 0-termination
of a string. I am not certain, but that is why I think the existing
code allocates a buffer that is 1 byte too long -- but then it fails
to set this byte to 0.

Fix pager regression
The patch to fix paging with redirection caused a regression in the
internal AdaCore test suite. The problem occurs when running an MI
command from the CLI using interpreter-exec, when paging is enabled.
This scenario isn't covered by the current test suite, so this patch
includes a new test.
The problem is that, in this situation, MI does:
fputs_unfiltered (strcmp (context->command, "target-select") == 0
? "^connected" : "^done", mi->raw_stdout);
Here raw_stdout is a stdio_file wrapping stdout, so the pager thinks
that it is ok to buffer the output. However, in this setup, it isn't
ok, and flushing the wrap buffer doesn't really work properly. Also,
MI next does:
mi_out_put (uiout, mi->raw_stdout);
... but this uses ui_file::write, which also doesn't flush the wrap
buffer.
I think all this will be fixed by the pager rewrite series I'm working
on. However, in the meantime, adding the old gdb_stdout check back to
the pager fixes this problem.

elf: Set p_align to the minimum page size if possible
Currently, on 32-bit and 64-bit ARM, it seems that ld generates p_align
values of 0x10000 even if no section alignment is greater than 0x1000.
The issue is more general and probably affects other targets with multiple
page sizes.
While file layout absolutely must take 64K page size into account, that
does not have to be reflected in the p_align value. If running on a 64K
kernel, the file will be loaded at a 64K page boundary by necessity. On
a 4K kernel, 64K alignment is not needed.
The glibc loader has been fixed to honor p_align:
https://sourceware.org/bugzilla/show_bug.cgi?id=28676

fs/binfmt_elf: use PT_LOAD p_align values for suitable start address
This means that on 4K kernels, we will start to do extra work for 64K
p_align, but this pointless for pretty much all binaries (whose section
alignment rarely exceeds 16).
The minimum page size is used, instead of the maximum section alignment
due to this glibc bug:
https://sourceware.org/bugzilla/show_bug.cgi?id=28688
It has been fixed in glibc 2.35. But linker output must work on existing
glibc binaries.
1. Set p_align to the minimum page size while laying out segments aligning
to the maximum page size or section alignment. The run-time loader can
align segments to the minimum page size or above, depending on system page
size.
2. If -z max-page-size=NNN is used, p_align will be set to the maximum
page size or the largest section alignment.
3. If a section requires alignment higher than the minimum page size,
don't set p_align to the minimum page size.
4. If a section requires alignment higher than the maximum page size,
set p_align to the section alignment.
5. For objcopy, when the minimum page size != the maximum page size,
p_align may be set to the minimum page size while segments are aligned
to the maximum page size. In this case, the input p_align will be
ignored and the maximum page size will be used to align the ouput
segments.
6. Update linker to disallow the common page size > the maximum page size.
7. Update linker to avoid the common page size > the maximum page size.
8. Adjust pru_irq_map-1.d to expect p_align == sh_addralign:

gdb/testsuite: fix inferior-clone.exp for native-extended-gdbserver
003aae076207dbf32f98ba846158fc32669ef85f (gdb: Copy inferior properties
in clone-inferior) introduced a testcase that fails when testing with
the native-extended-gdbserver board:
Running ../gdb/testsuite/gdb.base/inferior-clone.exp ...
FAIL: gdb.base/inferior-clone.exp: inferior 2: clone-inferior
FAIL: gdb.base/inferior-clone.exp: inferior 3: clone-inferior
The error is as follows:
clone-inferior
[New inferior 2]
Added inferior 2 on connection 1 (extended-remote localhost:2346)
(gdb) FAIL: gdb.base/inferior-clone.exp: inferior 2: clone-inferior
This fails because the testcase only expect the 'Added inferior 2' part
of the message. The 'on connection 1 [...]' part is unexpected.
Fix by adjusting the testcase to a account for the possible trailing
part of the message.
Tested on x86_64-linux with native-extende-gdbserver and unix boards.

gdb: fall back on sigpending + sigwait if sigtimedwait is not available
A call to sigwait was introduced that passes nullptr as the second
argument, this call is only reached if sigtimedwait is not supported.
The original patch was written for macOS, I assume on that target
passing nullptr as the second argument is fine.
On my GNU/Linux box, the man-page for sigwait doesn't mention that
nullptr is allowed for the second argument, so my assumption would be
that nullptr is not OK, and, if I change the '#ifdef
HAVE_SIGTIMEDWAIT' introduced by the above patch to '#if 0', and
rebuild on GNU/Linux, I see the same warning that I see on GNU/Hurd.
I propose that we stop passing nullptr as the second argument to
sigwait, and instead pass a valid int pointer. The value returned in
the int can then be used in an assert.
For testing, I (locally) made the change to the #ifdef I mentioned
above, compiled GDB, and ran the usual tests, this meant I was using
sigwait instead on sigtimedwait on GNU/Linux, I saw no regressions.

gas: rework handling of backslashes in quoted symbol names
Strange effects can result from the present handling, e.g.:
.if 1
"backslash\\":
.endif
yields first (correctly) "missing closing `"'" but then also "invalid
character '\' in mnemonic" and further "end of file inside conditional".
Symbols names ending in \ are in principle not expressable with that
scheme.
Instead of recording whether a backslash was seen, inspect the
subsequent character right away. Only accept \\ (meaning a single
backslash in the resulting symbol name) and \" (meaning an embedded
double quote in the resulting symbol name) for now, warning about any
other combination.
While perhaps not necessary immediately, also permit concatenated
strings to form a symbol name. This may become useful if going forward
we would want to support \<octal> or \x<hex> sequences, where closing
and re-opening quotes can be useful to delimit such sequences.
The ELF "Multibyte symbol names" test gets switched away from using
.set, as that would now also mean excluding nios2 and pru. By using
.equiv instead, even the existing #notarget can be dropped. (For h8300
the .section directive additionally needs attributes specified, to avoid
a target specific warning.)

[gdb/cli] Improve show logging output
Before commit
3b6acaee895 "Update more calls to add_prefix_cmd" we had the
following output for "show logging":
...
$ gdb -q -batch -ex "set trace-commands on" \
-ex "set logging off" \
-ex "show logging" \
-ex "set logging on" \
-ex "show logging"
+set logging off
+show logging
Future logs will be written to gdb.txt.
Logs will be appended to the log file.

Debug output will be logged and displayed.
+set logging on
+show logging
Currently logging to "gdb.txt".
Logs will be appended to the log file.
Output will be logged and displayed.
Debug output will be logged and displayed.
...
After that commit we have instead:
...
+set logging off
+show logging
debugredirect: The logging output mode is off.
file: The current logfile is "gdb.txt".
overwrite: Whether logging overwrites or appends to the log file is off.
redirect: The logging output mode is off.
+set logging on
+show logging
debugredirect: The logging output mode is off.
file: The current logfile is "gdb.txt".
overwrite: Whether logging overwrites or appends to the log file is off.
redirect: The logging output mode is off.
...
which gives less clear output for some subcommands.
OTOH, it's explicit about whether boolean values are on or off.
The new text seems to have been chosen to match the set/show help texts:
...
(gdb) help show logging
Show logging options.
List of show logging subcommands:
show logging debugredirect -- Show the logging debug output mode.
show logging file -- Show the current logfile.
show logging overwrite -- \
Show whether logging overwrites or appends to the log file.
show logging redirect -- Show the logging output mode.
...
Make the show logging messages more clear, while still keep the boolean
values explicit, such that we have:
...
$ ./gdb.sh -q -batch -ex "show logging"
logging debugredirect: off: \
Debug output will go to both the screen and the log file.
logging enabled: off: Logging is disabled.
logging file: The current logfile is "gdb.txt".
logging overwrite: off: Logging appends to the log file.
logging redirect: off: Output will go to both the screen and the log file.
