gdb_vecs.h: Avoid self move assign
While working on another patch I ran into an issue with
unordered_remove (in gdb_vecs.h), where removing the last item of the
vector can cause a self move assign.
When compiling the C++ standard library in debug mode (with
-D_GLIBCXX_DEBUG=1) this causes an error to trigger.
I've fixed the issue in this patch and provided a unit test.
The provided unit test includes an assignment operator which checks
for self move assign, this removes the need to compile with
-D_GLIBCXX_DEBUG=1 in order to spot the bug. If you're keen to see
the error reported from the C++ standard library then remove operator=
from the unit test and recompile GDB with -D_GLIBCXX_DEBUG=1.

* Makefile.in (SUBDIR_UNITTESTS_SRCS): Add new file to the list.
* unittests/vec-utils-selftests.c: New file.

Remove can_highlight from TUI windows
Each TUI window has a "can_highlight" member. However, this has the

i386: Only check suffix in instruction mnemonic
We should check suffix in instruction mnemonic when matching instruction.
In Intel syntax, normally we check for memory operand size. But the same
mnemonic with 2 different encodings can have the same memory operand
size and i.suffix is set to LONG_DOUBLE_MNEM_SUFFIX from memory operand
size in Intel syntax to distinguish them. When there is no suffix in

[Patch][binutils][arm] Create a new generic coprocessor array [3/10]
Hi,
This patch is part of a series that adds support for Armv8.6-A
(Matrix Multiply and BFloat16 extensions) to binutils.
Some generic instructions match a large range of encoding space (e.g.
stc, mcr, mrc).
Currently these instructions are in the coprocessor_opcodes array, which
means they are checked before many other instructions when disassembling
arm and thumb32 codes.
This patch moves the generic instructions into a separate array to be
checked later on.
This is done in order to avoid instruction conflict between the generic
instructions and newer ones -- this has already been seen with MVE, and
is also a problem with BFloat16.
One way to avoid the conflict could be to swap the search order between
coprocessor_opcodes and neon_opcodes.
We avoid this since it's a larger change that may introduce extra bugs
(that aren't caught by the testsuite).
We have decided against searching the generic array after searching the
arm specific and thumb32 specific arrays with a similar reasoning about
keeping the change small.
Regression tested with arm-none-linux-gnueabihf.

[gdb/contrib] Add words.sh script
Add a script that takes a list of files as arguments and output a list of
words from the C comments with their frequencies.
For:
...
$ ./gdb/contrib/words.sh $(find gdb -type f -name "*.c" -o -name "*.h")
...
it generates a list of ~15000 words prefixed with frequency.
This could be used to generate a dictionary that is kept as part of the
sources, against which new code can be checked, generating a warning or
error. The hope is that misspellings would trigger this frequently, and rare
words rarely, otherwise the burden of updating the dictionary would be too
much.
And for:
...
$ ./gdb/contrib/words.sh -f 1 $(find gdb -type f -name "*.c" -o -name "*.h")

it generates a list of ~5000 words with frequency 1.
This can be used to scan for misspellings manually.

Remove CR16C support
I think it is past time to remove CR16C support. CR16C was added in
2004, and only for ld. gas and binutils support is lacking, and there
have been no commits to bfd/elf32-cr16c.c other than warning fixes or
global maintainers making changes to all targets. I see no maintainer
listed for CR16C, and no commits from anyone at NSC supporting the
target. Furthermore, at the time the CR16 support was added in 2007,
config.sub was changed upstream to no longer recognise cr16c as a
valid cpu. That means the CR16C ld support is only available as a
secondary target by configuring with, for example,
--enable-targets=all or --enable-targets=cr16c-unknown-elf. No
testing of the CR16C target is possible.

Style disassembly in the TUI
This patch changes the TUI disassembly window to style its contents.
The styling should be identical to what is seen in the CLI. This
involved a bit of rearrangement, so that the source and disassembly
windows could share both the copy_source_line utility function, and
the ability to react to changes in "set style enabled".

GENERATE_SHLIB_SCRIPT vs. EMBEDDED.
A target that sets EMBEDDED non-empty is one that doesn't want to put
the ELF file header or program header in a memory image. Likely the
target isn't interested in supporting dynamically loaded executables,
shared libraries, or PIEs, because loaders for such binaries generally
require program headers to be present. This isn't 100% true though.
The target might be one where the loader accesses the file system in
order to retrieve headers.
Also, note that not all "shared libraries" require gcc -shared or the
shared library support in the linker. I believe one implementation of
shared libraries on uclinux is like this.
So, this patch removes GENERATE_SHLIB_SCRIPT and GENERATE_PIE_SCRIPT
in most emulparams files where EMBEDDED is set, restoring the shared
lib and pie support in emulparams files that unset EMBEDDED after
including a file where the support is removed.
Exceptions to the general rule that EMBEDDED disables shared libs are:
arm*-*-symbianelf*, where the OS wants shared library support
without ELF program headers in the image, and
sh*-*-uclinux*, where I've left things as they were, ie. both
EMBEDDED and GENERATE_SHLIB_SCRIPT because I'm unsure as to the
shared library scheme.

[ARM, thumb] Fix disassembling bug after reloading a symbol file
The speed optimization from commit
5f6cac4085c95c5339b9549dc06d4f9184184fa6
made GDB skip reloading all symbols when the same symbol file is reloaded.
As a result, ARM targets only read the mapping symbols the first time we
load a symbol file. When reloaded, the speed optimization above will
cause an early return and gdbarch_record_special_symbol won't be called to
save mapping symbol data, which in turn affects disassembling of thumb
instructions.
First load and correct disassemble output:
Dump of assembler code for function main:
0x0000821c <+0>: bx pc
0x0000821e <+2>: nop
0x00008220 <+4>: mov r0, #0
0x00008224 <+8>: bx lr
Second load and incorrect disassemble output:
Dump of assembler code for function main:
0x0000821c <+0>: bx pc
0x0000821e <+2>: nop
0x00008220 <+4>: movs r0, r0
0x00008222 <+6>: b.n 0x8966
0x00008224 <+8>: vrhadd.u16 d14, d14, d31
This happens because the mapping symbol data is stored in an objfile_key-based
container, and that data isn't preserved across the two symbol loading
operations.
The following patch fixes this by storing the mapping symbol data in a
bfd_key-based container, which doesn't change as long as the bfd is the same.
I've also added a new test to verify the correct disassemble output.

gdb: Add new commands to list module variables and functions
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

gdb/fortran: Add new 'info modules' command
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.
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.

Implement convenience functions to examine GDB settings.
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).

few anomalies pointed out by this:
- arithmetic insns (add, sub, etc) allow defaulting when their immediate

- 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.

the overall template table size by 4 bytes per entry.

x86: drop stray W
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).

Clean up ada-lang.h
This patch cleans up ada-lang.h:
- Some functions just don't exist anymore, remove their declaration
- Some functions are implemented in ada-lang.c and only used there, make
them static to that file.
I moved some functions higher in the file to avoid having to
forward-declare them, but the implementations are unchanged.
gdb/ChangeLog:
* ada-lang.h (GROW_VECT): Move to ada-lang.c.
(grow_vect): Remove declaration.
(ada_type_of_array): Remove declaration.
(ada_update_initial_language): Remove declaration.
(ada_fold_name): Remove declaration.
(ada_fill_in_ada_prototype): Remove declaration.
(user_select_syms): Remove declaration.
