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.
Update the default ISA spec from 2.2 to 20191213 will change the default
version of i from 2.0 to 2.1. Since zicsr and zifencei are separated
from i 2.1, users need to add them in the architecture string if they need
fence.i and csr instructions. Besides, we also allow old ISA spec can
recognize zicsr and zifencei, but we won't output them since they are
already included in the i extension when i's version is less than 2.1.

target_announce_detach was added in commit 0f48b757 ("Factor out
"Detaching from program" message printing"). There, Pedro wrote:
(For now, I left the couple targets that print this a bit differently
alone. Maybe this could be further pulled out into infcmd.c. If we
did that, and those targets want to continue printing differently,
this new function could be converted to a target method.)
It seems to me that the differences aren't very big, and in some cases
other targets handled the output a bit more nicely. In particular,
some targets will print a different message when exec_file==NULL,
rather than printing the same output with an empty string as
exec_file.
This patch incorporates the nicer output into target_announce_detach,
then changes the remaining ports to use this function.
This introduces target_announce_attach, by analog with
target_announce_detach. Then it converts existing targets to use
this, rather than emitting their own output by hand.
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.
This change will conflict with Tom's change here:
https://sourceware.org/pipermail/gdb-patches/2022-January/184724.html
Where Tom changes the set/show functions that I delete. My suggestion
is that the set/show functions still be deleted even after Tom's
patch (or instead of Tom's patch).
For testing I've build GDB on GNU/Hurd, and manually tested these
functions. I did a grep over the testsuite, and don't believe the
existing error messages are being checked for in any tests.
windows-tdep.c checks the result of xmalloc, which isn't necessary. I
initially removed this dead check, but then went a bit further and
modified the code so that some "goto"s and explicit memory management
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.
language_info calls:
show_language_command (NULL, 1, NULL, NULL);
... "knowing" that show_language_command does not use its ui_file
parameter. However, this was changed in commit 7514a661
("Consistently Use ui_file parameter to show callbacks").
This patch changes language_info to pass a ui_file.
It took a while to write the test -- this function is only called when
'verbose' is on and when switching the "expected" language in auto
mode.
langs.exp currently has some fails for me because the stack trace
includes full paths to the source files.
FAIL: gdb.base/langs.exp: up to foo in langs.exp
FAIL: gdb.base/langs.exp: up to cppsub_ in langs.exp
FAIL: gdb.base/langs.exp: up to fsub in langs.exp
This fixes the failures by making the filename regexps a bit more lax.
To avoid issues like that addressed by 6e3e5c9e41 ("x86: extend SSE
check to PCLMULQDQ, AES, and GFNI insns"), base the check on opcode
attributes and operand types.
As already indicated in a remark when introducing these templates, the
"commutative" attribute is ignored for legacy encoding templates. Hence
it is possible to shorten a number of templates by specifying C directly
rather than through a template parameter. I think this helps readability
a bit.
Neither non-64-bit code nor uses with a non-zero offset from a symbol
should be converted to PLT32, as an eventual PLT entry would not express
what was requested.
I just realized that I forgot to update the year before pushing the
patch that created this file. Since it landed after the global
copyright year update have been done, this file’s copyright year is
updated.
This patch fixes that.

Internally, AdaCore has a test that is equivalent to (really a direct
translation of) gdb.base/gnu_vector.exp. On 32-bit RISC-V, the
"return" part of this test fails.
Joel tracked this down to riscv_return_value returning
RETURN_VALUE_ABI_RETURNS_ADDRESS. Using
RETURN_VALUE_ABI_PRESERVES_ADDRESS is more correct here, and fixes the
bug.
I tested this for both 32- and 64-bit RISC-V using the AdaCore
internal test suite, and Andrew Burgess tested it using
gnu_vector.exp.
Most of the expression-dumping code uses filtered output, but a few
functions did not. This patch cleans up these instance.
Note that this won't cause any behavior change, because the only calls
to dump_prefix_expression pass in gdb_stdlog. However, in the long
run it's easier to audit the code if the number of uses of _unfiltered
is reduced.
This changes one terminal_info implementation, and
default_terminal_info, to use filtered output. Other implementations
of this method already use filtered output.
I can't compile go32-nat.c, so this is a 'best effort' patch.
gnu-nat.c has a number of ordinary commands that should use filtered
output. In a few cases, I changed the output to use gdb_stderr as
well. I can't compile this file, so this patch is split out as a
"best effort".
Various targets introduce their own commands, which then use
unfiltered output. It's better to use filtered output by default, so
this patch fixes the instances I found.
There are several commands that may optionally send their output to a
file -- they take an optional filename argument and open a file. This
patch changes these commands to use filtered output. The rationale
here is that, when printing to gdb_stdout, filtering is appropriate --
it is, and should be, the default for all commands. And, when writing
to a file, paging will not happen anyway (it only happens when the
stream==gdb_stdout), so using the _filtered form will not change
anything.
This changes the kill command to use filtered output. I split this
one into its own patch because, out of an abundance of caution, I
changed the function to call bfd_cache_close_all a bit earlier, in
case pagination caused an exception.
