When calling the language la_print_typedef method, don't include a
newline at the end, instead print the newline from the users of
la_print_typedef.
This change will be useful in a later commit when the output from
la_print_typedef will be placed into an MI output field, in which case
the trailing newline is not required.
There should be no user visible changes after this commit.

This patch adds two new commands "info module functions" and "info
module variables". These commands list all of the functions and
variables grouped by module and then by file.
For example:
(gdb) info module functions
All functions in all modules:
Module "mod1":
File /some/path/gdb/testsuite/gdb.fortran/info-types.f90:
35: void mod1::__copy_mod1_M1t1(Type m1t1, Type m1t1);
25: void mod1::sub_m1_a(integer(kind=4));
31: integer(kind=4) mod1::sub_m1_b(void);
Module "mod2":
File /some/path/gdb/testsuite/gdb.fortran/info-types.f90:
41: void mod2::sub_m2_a(integer(kind=4), logical(kind=4));
49: logical(kind=4) mod2::sub_m2_b(real(kind=4));
The new commands take set of flags that allow the output to be
filtered, the user can filter by variable/function name, type, or
containing module.
As GDB doesn't currently track the relationship between a module and
the variables or functions within it in the symbol table, so I filter
based on the module prefix in order to find the functions or variables
in each module. What this makes clear is that a user could get this
same information using "info variables" and simply provide the prefix
themselves, for example:
(gdb) info module functions -m mod1 _a
All functions matching regular expression "_a",
in all modules matching regular expression "mod1":
Module "mod1":
File /some/path/gdb/testsuite/gdb.fortran/info-types.f90:
25: void mod1::sub_m1_a(integer(kind=4));
Is similar to:
(gdb) info functions mod1::.*_a.*
All functions matching regular expression "mod1::.*_a":
File /some/path/gdb/testsuite/gdb.fortran/info-types.f90:
25: void mod1::sub_m1_a(integer(kind=4));
The benefits I see for a separate command are that the user doesn't
have to think (or know) about the module prefix format, nor worry
about building a proper regexp. The user can also easily scan across
modules without having to build complex regexps.
The new function search_module_symbols is extern in this patch despite
only being used within symtab.c, this is because a later patch in this
series will also be using this function from outside symtab.c.
This patch is a new implementation of an idea originally worked on by
Mark O'Connor, Chris January, David Lecomber, and Xavier Oro from ARM.

Add a new command 'info modules' that lists all of the modules GDB
knows about from the debug information.
A module is a debugging entity in the DWARF defined with
DW_TAG_module, currently Fortran is known to use this tag for its
modules. I'm not aware of any other language that currently makes use
of DW_TAG_module.
The output style is similar to the 'info type' output:
(gdb) info modules
All defined modules:
File info-types.f90:
16: mod1
24: mod2
(gdb)
Where the user is told the file the module is defined in and, on the
left hand side, the line number at which the module is defined along
with the name of the module.

Mark O'Connor, Chris January, David Lecomber, and Xavier Oro from ARM.

* gdb.base/setshow.exp: Test $_gdb_setting and $_gdb_setting_str.
* gdb.base/settings.exp: Test all settings types using
$_gdb_maint_setting and $_gdb_maint_setting_str in proc_show_setting,
that now verifies that the value of "maint show" is the same as
returned by the settings functions. Test the type of the
maintenance settings.
* gdb.base/default.exp: Update show_conv_list.
The new convenience functions $_gdb_setting and $_gdb_setting_str
provide access to the GDB settings in user-defined commands.
Similarly, $_gdb_maint_setting and $_gdb_maint_setting_str
provide access to the GDB maintenance settings.
The patch was developed following a comment of Eli about the
'set may-call-functions'. Eli said that user-defined functions
should have a way to change their behavior according to this setting.
Rather than have a specialized $_may_call_functions, this patch
implements a general way to access any GDB setting.
Compared to doing such access via Python 'gdb.parameter' and/or
'gdb.execute("set somesetting tosomevalue"):
* The 'with' command is much better than the above python usage:
if the user types C-c or an error happens between the set pagination off
and the python "set pagination on", the above python
does not restore the original setting.
* Effectively, with the "gdb.parameter" python one liner, it is possible to do
simple 'if' conditions, such as set and restore pagination.
But mixing the "python if" within canned
sequence of commands is cumbersome for non trivial combinations.
E.g. if several commands have to be done for a certain condition
accessed from python, I guess something like will be needed:
python if __some_setting: gdb.execute("some command")
python if __some_setting: gdb.execute("some other command")
python if __some_setting: gdb.execute("some different command")
(without speaking about nested "if-s").
With the convenience function:
if $_gdb_setting("some_setting")
some command
some other command
some different command
end
Integer settings (for example print elements) will also be more difficult
to use.
For example, a user defined function that scans and prints a linked list
might want to use the value of "set print elements" to stop printing
the linked list.
Doing that by mixing python expression/if is likely doable, but seems
not easy with the above one liners.
So, in summary, the $_gdb_setting and $_gdb_setting_str avoids to have the
heterogeneous mix of python and GDB commands in one single script
(and of course, it works even if python is not configured, but that
must be an unusual setup I guess).

Proc gdb_test_multiple builds up and executes a gdb_expect expression with
pattern/action clauses. The clauses are either implicit (added by
gdb_test_multiple) or explicit (passed via the gdb_test_multiple parameter
user_code).
However, there are a few implicit clauses which are inserted before the
explicit ones, making sure those take precedence.
Add an -early pattern flag for a gdb_test_multiple user_code clause to specify
that the clause needs to be inserted before any implicit clause.
Using this pattern flag, we can f.i. setup a kfail for an assertion failure
<assert> during gdb_continue_to_breakpoint by the rewrite:
...
gdb_continue_to_breakpoint <msg> <pattern>
...
into:
...
set breakpoint_pattern "(?:Breakpoint|Temporary breakpoint) .* (at|in)"
gdb_test_multiple "continue" "continue to breakpoint: <msg>" {
-early -re "internal-error: <assert>" {
setup_kfail gdb/nnnnn "*-*-*"
exp_continue
}
-re "$breakpoint_pattern <pattern>\r\n$gdb_prompt $" {
pass $gdb_test_name
}
}

This is a shorthand for the immediate argument being 0, as described here:
https://developer.arm.com/docs/ddi0596/latest/base-instructions-alphabetic-order/ldraa-ldrab-load-register-with-pointer-authentication

Prior to changing the logic in the assembler install tests to make sure
the present defaulting of operand sizes won't get broken. There are a
few anomalies pointed out by this:
- arithmetic insns (add, sub, etc) allow defaulting when their immediate
fits in (signed) 8 bits, but they fail to assemble with larger values,
- mov, other than arithmetic insns, doesn't allow any defaulting,
- movsx/movzx default to byte sources (in AT&T mode), and their special
casing needs to be adjusted first
- bt and friends allow defaulting, while shl and friends don't,
- ambiguous AVX and AVX512 insns don't allow defaulting.
This should ultimately all become consistent (perhaps with the exception
some of the SIMD insns); respective tests will be added to the test
cases here as the issues get addressed.
Now that the opcode table gets preprocessed, undo parts of commit
dc821c5f9a ("x86: replace Reg8, Reg16, Reg32, and Reg64"): Have the
preprocessor handle the expansion there, while making the expansions
explicit in i386-gen and the register table.
The flag is used to indicate opcodes which can be switched between byte
and word/dword/qword forms (in a "canonical" way). Obviously it's quite
odd then to see it on insns not allowing for byte operands in the first
place. As a result the opcode bytes need to be adjusted accordingly,
which includes comparisons done in optimize_encoding().
To make re-introduction of such issues less likely have i386-gen
diagnose it (in a generally non-fatal way for now).

As of 7bb4305982, we no longer need
a nullterminated linkage_name to look up the entry in the hash table.
So this patch makes it so we only make the copy if the entry was
not found.
By auditing all callers of symbol_set_names, I found out that all cases
where the string may not be nullterminated already pass true for COPY_NAME.
So here, I am documenting that as a requirement and am removing the code
that relies on undefined behavior in symbol_set_names (it accessed the string
past the provided length to check for nulltermination). Note that the Ada
case at the beginning of symbol_set_names was already relying on this.
