492325c4b7 gdb: fix some clang-tidy readability-misleading-indentation warnings 
I have warnings like these showing in my editor all the time, so I
thought I'd run clang-tidy with this diagnostic on all the files (that I
can compile) and fix them.

There is still one warning, in utils.c, but that's because some code
is mixed up with preprocessor macros (#ifdef TUI), so I think there no
good solution there.

1285ce8629 Always call the wrap_here method 
This changes all existing calls to wrap_here to call the method on the
appropriate ui_file instead.  The choice of ui_file is determined by
context.

6c92c33953 Convert wrap_here to use integer parameter 
I think it only really makes sense to call wrap_here with an argument
consisting solely of spaces.  Given this, it seemed better to me that
the argument be an int, rather than a string.  This patch is the
result.  Much of it was written by a script.

a5d8391846 gdb: use try/catch around a gdb_disassembler::print_insn call 
While investigating some disassembler problems I ran into this case;
GDB compiled on a 32-bit arm target, with --enable-targets=all.  Then
in GDB:

  (gdb) set architecture i386
  (gdb) disassemble 0x0,+4
  unknown disassembler error (error = -1)

This is interesting because it shows a case where the libopcodes
disassembler is returning -1 without first calling the
memory_error_func callback.  Indeed, the return from libopcodes
happens from this code snippet in i386-dis.c in the print_insn
function:

  if (address_mode == mode_64bit && sizeof (bfd_vma) < 8)
    {
      (*info->fprintf_func) (info->stream,
			     _("64-bit address is disabled"));
      return -1;
    }

Notice how, prior to the return the disassembler tries to print a
helpful message out, but GDB doesn't print this message.

The reason this message goes missing is the call stack, it looks like
this:

  gdb_pretty_print_disassembler::pretty_print_insn
    gdb_disassembler::print_insn
      gdbarch_print_insn
        ...
          i386-dis.c:print_insn

When i386-dis.c:print_insn returns -1 this is handled in
gdb_disassembler::print_insn, where an exception is thrown.  However,
the actual printing of the disassembler output is done in
gdb_pretty_print_disassembler::pretty_print_insn, and is only done if
an exception is not thrown.

In this commit I change this.  The pretty_print_insn now uses
try/catch around the call to gdb_disassembler::print_insn, if we catch
an error then we first print any pending output in the instruction
buffer, before rethrowing the exception.  As a result, even if an
exception is thrown we still print any pending disassembler output to
the screen; in the above case the helpful message will now be shown.

Before my patch we might expect to see this output:

  (gdb) disassemble 0x0,+4
  Dump of assembler code from 0x0 to 0x4:
     0x0000000000000000:	unknown disassembler error (error = -1)
  (gdb)

But now we see this:

  (gdb) disassemble 0x0,+4
  Dump of assembler code from 0x0 to 0x4:
     0x0000000000000000:	64-bit address is disabled
  unknown disassembler error (error = -1)

If the disassembler returns -1 without printing a helpful message then
we would still expect a change in output, something like:

  (gdb) disassemble 0x0,+4
  Dump of assembler code from 0x0 to 0x4:
     0x0000000000000000:
  unknown disassembler error (error = -1)

Which I think is still acceptable, though at this point I think a
strong case can be made that this is a disassembler bug (not printing
anything, but still returning -1).

Notice however, that the error message is always printed on a new line
now.  This is also true for the memory error case, where before we
might see this:

  (gdb) disassemble 0x0,+4
  Dump of assembler code from 0x0 to 0x4:
     0x00000000:	Cannot access memory at address 0x0

We now get this:

  (gdb) disassemble 0x0,+4
  Dump of assembler code from 0x0 to 0x4:
     0x00000000:
  Cannot access memory at address 0x0

For me, I'm happy to accept this change, having the error on a line by
itself, rather than just appended to the end of the previous line,
seems like an improvement, but I'm aware others might feel
differently, so I'd appreciate any feedback.

431be556b0 gdb: make disassembler fprintf callback a static member function 
The disassemble_info structure has four callbacks, we have three of
them as static member functions within gdb_disassembler, the fourth is
just a global static function.

However, this fourth callback, is still only used from the
disassemble_info struct, so there's no real reason for its special
handling.

This commit makes fprintf_disasm a static method within
gdb_disassembler.

There should be no user visible changes after this commit.

76b43c9b5c gdb: improve error reporting from the disassembler 
If the libopcodes disassembler returns a negative value then this
indicates that the disassembly failed for some reason.  In disas.c, in
the function gdb_disassembler::print_insn we can see how this is
handled; when we get a negative value back, we call the memory_error
function, which throws an exception.

The problem here is that the address used in the memory_error call is
gdb_disassembler::m_err_memaddr, which is set in
gdb_disassembler::dis_asm_memory_error, which is called from within
the libopcodes disassembler through the
disassembler_info::memory_error_func callback.

However, for this to work correctly, every time the libopcodes
disassembler returns a negative value, the libopcodes disassembler
must have first called the memory_error_func callback.

My first plan was to make m_err_memaddr a gdb::optional, and assert
that it always had a value prior to calling memory_error, however, a
quick look in opcodes/*-dis.c shows that there _are_ cases where a
negative value is returned without first calling the memory_error_func
callback, for example in arc-dis.c and cris-dis.c.

Now, I think that a good argument can be made that these disassemblers
must therefore be broken, except for the case where we can't read
memory, we should always be able to disassemble the memory contents to
_something_, even if it's just '.word 0x....'.  However, I certainly
don't plan to go and fix all of the disassemblers.

What I do propose to do then, is make m_err_memaddr a gdb::optional,
but now, instead of always calling memory_error, I add a new path
which just calls error complaining about an unknown error.  This new
path is only used if m_err_memaddr doesn't have a value (indicating
that the memory_error_func callback was not called).

To test this I just augmented one of the disassemblers to always
return -1, before this patch I see this:

  Dump of assembler code for function main:
     0x000101aa <+0>:	Cannot access memory at address 0x0

And after this commit I now see:

  Dump of assembler code for function main:
     0x000101aa <+0>:	unknown disassembler error (error = -1)

This doesn't really help much, but that's because there's no way to
report non memory errors out of the disasembler, because, it was not
expected that the disassembler would ever report non memory errors.

e0700ba44c gdb: make string-like set show commands use std::string variable 
String-like settings (var_string, var_filename, var_optional_filename,
var_string_noescape) currently take a pointer to a `char *` storage
variable (typically global) that holds the setting's value.  I'd like to
"mordernize" this by changing them to use an std::string for storage.

An obvious reason is that string operations on std::string are often
easier to write than with C strings.  And they avoid having to do any
manual memory management.

Another interesting reason is that, with `char *`, nullptr and an empty
string often both have the same meaning of "no value".  String settings
are initially nullptr (unless initialized otherwise).  But when doing
"set foo" (where `foo` is a string setting), the setting now points to
an empty string.  For example, solib_search_path is nullptr at startup,
but points to an empty string after doing "set solib-search-path".  This
leads to some code that needs to check for both to check for "no value".
Or some code that converts back and forth between NULL and "" when
getting or setting the value.  I find this very error-prone, because it
is very easy to forget one or the other.  With std::string, we at least
know that the variable is not "NULL".  There is only one way of
representing an empty string setting, that is with an empty string.

I was wondering whether the distinction between NULL and "" would be
important for some setting, but it doesn't seem so.  If that ever
happens, it would be more C++-y and self-descriptive to use
optional<string> anyway.

Actually, there's one spot where this distinction mattered, it's in
init_history, for the test gdb.base/gdbinit-history.exp.  init_history
sets the history filename to the default ".gdb_history" if it sees that
the setting was never set - if history_filename is nullptr.  If
history_filename is an empty string, it means the setting was explicitly
cleared, so it leaves it as-is.  With the change to std::string, this
distinction doesn't exist anymore.  This can be fixed by moving the code
that chooses a good default value for history_filename to
_initialize_top.  This is ran before -ex commands are processed, so an
-ex command can then clear that value if needed (what
gdb.base/gdbinit-history.exp tests).

Another small improvement, in my opinion is that we can now easily
give string parameters initial values, by simply initializing the global
variables, instead of xstrdup-ing it in the _initialize function.

In Python and Guile, when registering a string-like parameter, we
allocate (with new) an std::string that is owned by the param_smob (in
Guile) and the parmpy_object (in Python) objects.

This patch started by changing all relevant add_setshow_* commands to
take an `std::string *` instead of a `char **` and fixing everything
that failed to build.  That includes of course all string setting
variable and their uses.

string_option_def now uses an std::string also, because there's a
connection between options and settings (see
add_setshow_cmds_for_options).

The add_path function in source.c is really complex and twisted, I'd
rather not try to change it to work on an std::string right now.
Instead, I added an overload that copies the std:string to a `char *`
and back.  This means more copying, but this is not used in a hot path
at all, so I think it is acceptable.

af7f8f52dd gdb: make add_setshow commands return set_show_commands 
Some add_set_show commands return a single cmd_list_element, the one for
the "set" command.  A subsequent patch will need to access the show
command's cmd_list_element as well.  Change these functions to return a
new structure type that holds both pointers.

I initially only modified add_setshow_boolean_cmd (the one I needed),
but I think it's better to change the whole chain to keep everything in
sync.

gdb/ChangeLog:

	* command.h (set_show_commands): New.
	(add_setshow_enum_cmd, add_setshow_auto_boolean_cmd,

dda83cd783 gdb, gdbserver, gdbsupport: fix leading space vs tabs issues 
Many spots incorrectly use only spaces for indentation (for example,
there are a lot of spots in ada-lang.c).  I've always found it awkward
when I needed to edit one of these spots: do I keep the original wrong
indentation, or do I fix it?  What if the lines around it are also
wrong, do I fix them too?  I probably don't want to fix them in the same
patch, to avoid adding noise to my patch.

So I propose to fix as much as possible once and for all (hopefully).

One typical counter argument for this is that it makes code archeology
more difficult, because git-blame will show this commit as the last
change for these lines.  My counter counter argument is: when
git-blaming, you often need to do "blame the file at the parent commit"
anyway, to go past some other refactor that touched the line you are
interested in, but is not the change you are looking for.  So you
already need a somewhat efficient way to do this.

Using some interactive tool, rather than plain git-blame, makes this
trivial.  For example, I use "tig blame <file>", where going back past
the commit that changed the currently selected line is one keystroke.
It looks like Magit in Emacs does it too (though I've never used it).
Web viewers of Github and Gitlab do it too.  My point is that it won't
really make archeology more difficult.

The other typical counter argument is that it will cause conflicts with
existing patches.  That's true... but it's a one time cost, and those
are not conflicts that are difficult to resolve.  I have also tried "git
rebase --ignore-whitespace", it seems to work well.  Although that will
re-introduce the faulty indentation, so one needs to take care of fixing
the indentation in the patch after that (which is easy).

78344df7b5 gdb/disassembly: Update to handle non-statement addresses 
After the introduction of support for non-statement addresses in the
line table, the output for 'disassemble /m' can be broken in some
cases.

With the /m format disassembly GDB associates a set of addresses with
each line, these addresses are then sorted and printed for each line.

When the non-statement support was added GDB was incorrectly told to
ignore non-statement instructions, and not add these to the result
table.  This means that these instructions are completely missing from
the output.

This commit removes the code that caused non-statement lines to be
ignored.

A result of this change is that GDB will now potentially include new
line numbers in the 'disassemble /m' output, lines that previously
were only in the line table as non-statement lines will now appear in
the disassembly output.  This feels like an improvement though.

gdb/ChangeLog:

	* disasm.c (do_mixed_source_and_assembly_deprecated): Don't
	exclude non-statement entries.

gdb/testsuite/ChangeLog:

	* gdb.dwarf2/dw2-disasm-over-non-stmt.exp: New file.

8c95582da8 gdb: Add support for tracking the DWARF line table is-stmt field 
This commit brings support for the DWARF line table is_stmt field to
GDB.  The is_stmt field is used by the compiler when a single source
line is split into multiple assembler instructions, especially if the
assembler instructions are interleaved with instruction from other
source lines.

The compiler will set the is_stmt flag false from some instructions
from the source lines, these instructions are not a good place to
insert a breakpoint in order to stop at the source line.
Instructions which are marked with the is_stmt flag true are a good
place to insert a breakpoint for that source line.

Currently GDB ignores all instructions for which is_stmt is false.
This is fine in a lot of cases, however, there are some cases where
this means the debug experience is not as good as it could be.

Consider stopping at a random instruction, currently this instruction
will be attributed to the last line table entry before this point for
which is_stmt was true - as these are the only line table entries that
GDB tracks.  This can easily be incorrect in code with even a low
level of optimisation.

With is_stmt tracking in place, when stopping at a random instruction
we now attribute the instruction back to the real source line, even
when is_stmt is false for that instruction in the line table.

When inserting breakpoints we still select line table entries for
which is_stmt is true, so the breakpoint placing behaviour should not
change.

When stepping though code (at the line level, not the instruction
level) we will still stop at instruction where is_stmt is true, I
think this is more likely to be the desired behaviour.

Instruction stepping is, of course, unchanged, stepping one
instruction at a time, but we should now report more accurate line
table information with each instruction step.

The original motivation for this work was a patch posted by Bernd
here:
  https://sourceware.org/ml/gdb-patches/2019-11/msg00792.html

As part of that thread it was suggested that many issues would be
resolved if GDB supported line table views, this isn't something I've
attempted in this patch, though reading the spec, it seems like this
would be a useful feature to support in GDB in the future.  The spec
is here:
  http://dwarfstd.org/ShowIssue.php?issue=170427.1

And Bernd gives a brief description of the benefits here:
  https://sourceware.org/ml/gdb-patches/2020-01/msg00147.html

With that all said, I think that there is benefit to having proper
is_stmt support regardless of whether we have views support, so I
think we should consider getting this in first, and then building view
support on top of this.

The gdb.cp/step-and-next-inline.exp test is based off a test proposed
by Bernd Edlinger in this message:
  https://sourceware.org/ml/gdb-patches/2019-12/msg00842.html

4d89c1c79f Call disassemble_free_target in gdb 
Commit 20135676fc4c3912297c313b3e0d3cbd6cc402e3 ("PR24960, Memory leak
from disassembler") added "disassemble_free_target" to opcodes.  This
is used to free target-specific data when finished with a
disassembler.

This patch changes gdb to call this function where needed.

6c2659886f gdb: add back declarations for _initialize functions 
I'd like to enable the -Wmissing-declarations warning.  However, it
warns for every _initialize function, for example:

      CXX    dcache.o
    /home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’:
    /home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations]
     _initialize_dcache (void)
     ^~~~~~~~~~~~~~~~~~

The only practical way forward I found is to add back the declarations,
which were removed by this commit:

    commit 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9
    Author: John Baldwin <jhb@FreeBSD.org>
    Date:   Sat Sep 9 11:02:37 2017 -0700

        Remove unnecessary function prototypes.

I don't think it's a big problem to have the declarations for these
functions, but if anybody has a better solution for this, I'll be happy
to use it.

046bebe1c0 Add more styling to "disassemble" 
This adds more styling to the disassemble command.  In particular,
addresses and function names in the disassembly are now styled.

This required fixing a small latent bug in set_output_style.  This
function always passed NULL to emit_style_escape; but when writing to
a file other than gdb_stdout, it should emit the style escape
directly.  (FWIW this is another argument for better integrating the
pager with ui_file and getting rid of this entire layer.)

2dc80cf8a5 Restrict use of minsym names when printing addresses in disassembled code 
build_address_symbolic contains some code which causes it to
prefer the minsym over the the function symbol in certain cases.
The cases where this occurs are the same as the "certain pathological
cases" that used to exist in find_frame_funname().

This commit largely disables that code; it will only prefer the
minsym when the address of minsym is identical to that of the address
under consideration AND the function address for the symbtab sym is
not the same as the address under consideration.

So, without this change, when using the dw2-ranges-func-lo-cold
executable from the gdb.dwarf2/dw2-ranges-func.exp test, GDB exhibits
the following behavior:

(gdb) x/5i foo_cold
   0x40110d <foo+4294967277>:	push   %rbp
   0x40110e <foo+4294967278>:	mov    %rsp,%rbp
   0x401111 <foo+4294967281>:	callq  0x401106 <baz>
   0x401116 <foo+4294967286>:	nop
   0x401117 <foo+4294967287>:	pop    %rbp

On the other hand, still without this change, using the
dw2-ranges-func-hi-cold executable from the same test, GDB
does this instead:

(gdb) x/5i foo_cold
   0x401128 <foo_cold>:	push   %rbp
   0x401129 <foo_cold+1>:	mov    %rsp,%rbp
   0x40112c <foo_cold+4>:	callq  0x401134 <baz>
   0x401131 <foo_cold+9>:	nop
   0x401132 <foo_cold+10>:	pop    %rbp

This is inconsistent behavior.  When foo_cold is at a lower
address than the function's entry point, the symtab symbol (foo)
is displayed along with a large positive offset which would wrap
around the address space if the address space were only 32 bits wide.
(A later patch fixes this problem by displaying negative offsets.)

This commit makes the behavior uniform for both the "lo-cold" and
"hi-cold" cases:

lo-cold:

(gdb) x/5i foo_cold
   0x40110d <foo_cold>:	push   %rbp
   0x40110e <foo-18>:	mov    %rsp,%rbp
   0x401111 <foo-15>:	callq  0x401106 <baz>
   0x401116 <foo-10>:	nop
   0x401117 <foo-9>:	pop    %rbp

hi-cold:

(gdb) x/5i foo_cold
   0x401128 <foo_cold>:	push   %rbp
   0x401129 <foo+35>:	mov    %rsp,%rbp
   0x40112c <foo+38>:	callq  0x401134 <baz>
   0x401131 <foo+43>:	nop
   0x401132 <foo+44>:	pop    %rbp

In both cases, the symbol shown for the address at which foo_cold
resides is shown as <foo_cold>.  Subsequent offsets are shown as
either negative or positive offsets from the entry pc for foo.

When disassembling a function, care must be taken to NOT display
<+0> as the offset for the second range.  For this reason, I found
it necessary to add the "prefer_sym_over_minsym" parameter to
build_address_symbolic.  The type of this flag is a bool; do_demangle
ought to be a bool also, so I made this change at the same time.

gdb/ChangeLog:

	* valprint.h (build_address_symbolic): Add "prefer_sym_over_minsym"
	parameter.  Change type of "do_demangle" to bool.
	* disasm.c (gdb_pretty_print_disassembler::pretty_print_insn):
	Pass suitable "prefer_sym_over_minsym" flag to
	build_address_symbolic().  Don't output "+" for negative offsets.
	* printcmd.c (print_address_symbolic): Update invocation of
	build_address_symbolic to include a "prefer_sym_over_minsym"
	flag.
	(build_address_symbolic): Add "prefer_sym_over_minsym" parameter.
	Restrict cases in which use of minimal symbol is preferred to that
	of a found symbol.  Update comments.

268a13a5a3 Rename common to gdbsupport 
This is the next patch in the ongoing series to move gdbsever to the
top level.

This patch just renames the "common" directory.  The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top.  This approach makes the patches a bit
more tractable.

I chose the name "gdbsupport" for the directory.  However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.

89549d7f4d Remove trailing newlines from help text 
I noticed recently that some command had a trailing newline in its
"help" output.  So, I temporarily hacked cli-decode.c to print
something when a new command was installed that had a trailing newline
in its help message, and wrote this patch, which removes all the ones
I could find this way.  (There could still be a few more in *-nat
files.)

Tested on x86-64 Fedora 29.

81f47ac29f testsuite: Disable some tests when logging 
Fix up all failures encountered when running the testsuite with
GDB_DEBUG="infrun".

Some tests rely on enabling debugging for various components.  With
debugging on, this will be lost to the debug file.

Disable separate tty for mi tests when debugging.  This currently
does not work.

disasm.c should send errors to the stderr instead of the logfile.

Note that enabling debug for other components might still cause
additional errors above what has been fixed here.

	* disasm.c (set_disassembler_options): Send errors to stderr.

4de283e4b5 Revert the header-sorting patch 
Andreas Schwab and John Baldwin pointed out some bugs in the header
sorting patch; and I noticed that the output was not correct when
limited to a subset of files (a bug in my script).

So, I'm reverting the patch.  I may try again after fixing the issues
pointed out.

This patch sorts the include files for the files [a-f]*.[chyl].
The patch was written by a script.

Tested by the buildbot.

I will follow up with patches to sort the remaining files, by sorting
a subset, testing them, and then checking them in.

42a4f53d2b Update copyright year range in all GDB files. 
This commit applies all changes made after running the gdb/copyright.py
script.

Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

cbe5657196 Add output styles to gdb 
This adds some output styling to the CLI.

A style is currently a foreground color, a background color, and an
intensity (dim or bold).  (This list could be expanded depending on
terminal capabilities.)

A style can be applied while printing.  For ui-out, this is done by
passing the style constant as an argument.  For low-level cases,
fprintf_styled and fputs_styled are provided.

Users can control the style via a number of new set/show commands.  In
the interest of not typing many nearly-identical documentation
strings, I automated this.  On the down side, this is not very
i18n-friendly.

I've chose some default colors to use.  I think it would be good to
enable this by default, so that when users start the new gdb, they
will see the new feature.

Stylizing is done if TERM is set and is not "dumb".  This could be
improved when the TUI is available by using the curses has_colors
call.  That is, the lowest layer could call this without committing to
using curses everywhere; see my other patch for TUI colorizing.

I considered adding a new "set_style" method to ui_file.  However,
because the implementation had to interact with the pager code, I
didn't take this approach.  But, one idea might be to put the isatty
check there and then have it defer to the lower layers.

b926417afa Simple -Wshadow=local fixes 
This fixes all the straightforward -Wshadow=local warnings in gdb.  A
few standard approaches are used here:

* Renaming an inner (or outer, but more commonly inner) variable;
* Lowering a declaration to avoid a clash;
* Moving a declaration into a more inner scope to avoid a clash,
  including the special case of moving a declaration into a loop header.

I did not consider any of the changes in this patch to be particularly
noteworthy, though of course they should all still be examined.

f4bab6ff22 Expand "show disassembler-options" output 
I typed this:

    (gdb) help set disassembler-options
    Set the disassembler options.
    Usage: set disassembler-options OPTION [,OPTION]...

    See: 'show disassembler-options' for valid option values.

... so I tried what it said and got:

    (gdb) show disassembler-options
    The current disassembler options are ''

This surprised me a little, so this patch adds some text to explain
the situation when an architecture does not have disassembler options.

While there I noticed one more spot where gdb was not using the GNU
style for metasyntactic variables.  This patch fixes this as well.

471b9d1507 GDB PR tdep/8282: MIPS: Wire in `set disassembler-options' 
Implement MIPS target support for passing options to the disassembler,
complementing commit 65b48a81404c ("GDB: Add support for the new
set/show disassembler-options commands.").

This includes options that expect an argument, so adjust the generic
code and data structures used so as to handle such options.  So as to
give backends syntax flexibility no specific delimiter has been defined
to separate options from their respective arguments, so it has to be
included as the last character of the option name.  Completion code
however has not been adjusted and consequently option arguments cannot
be completed at this time.

Also the MIPS target has non-empty defaults for the options, so that ABI
names for the general-purpose registers respect our `set mips abi ...'
setting rather than always being determined from the ELF headers of the
binary file selected.  Handle these defaults as implicit options, never
shown to the user and always prepended to the user-specified options, so
that the latters can override the defaults.

The resulting output for the MIPS target is as follows:

(gdb) show disassembler-options
The current disassembler options are ''

The following disassembler options are supported for use with the
'set disassembler-options <option>[,<option>...]' command:

  no-aliases      Use canonical instruction forms.

  msa             Recognize MSA instructions.

  virt            Recognize the virtualization ASE instructions.

  xpa             Recognize the eXtended Physical Address (XPA) ASE
                  instructions.

  ginv            Recognize the Global INValidate (GINV) ASE instructions.

  gpr-names=ABI   Print GPR names according to specified ABI.
                  Default: based on binary being disassembled.

  fpr-names=ABI   Print FPR names according to specified ABI.
                  Default: numeric.

  cp0-names=ARCH  Print CP0 register names according to specified architecture.
                  Default: based on binary being disassembled.

  hwr-names=ARCH  Print HWR names according to specified architecture.
                  Default: based on binary being disassembled.

  reg-names=ABI   Print GPR and FPR names according to specified ABI.

  reg-names=ARCH  Print CP0 register and HWR names according to specified
                  architecture.

  For the options above, the following values are supported for "ABI":
    numeric 32 n32 64

  For the options above, the following values are supported for "ARCH":
    numeric r3000 r3900 r4000 r4010 vr4100 vr4111 vr4120 r4300 r4400 r4600
    r4650 r5000 vr5400 vr5500 r5900 r6000 rm7000 rm9000 r8000 r10000 r12000
    r14000 r16000 mips5 mips32 mips32r2 mips32r3 mips32r5 mips32r6 mips64
    mips64r2 mips64r3 mips64r5 mips64r6 interaptiv-mr2 sb1 loongson2e
    loongson2f loongson3a octeon octeon+ octeon2 octeon3 xlr xlp
(gdb)

which corresponds to what `objdump --help' used to print for the MIPS
target, with minor formatting changes, most notably option argument
lists being wrapped, but also the amount of white space separating
options from the respective descriptions.  The relevant part the new
code is now also used by `objdump --help', which means these formatting
changes apply to both outputs, except for argument list wrapping, which
is GDB-specific.

This also adds a separating new line between the heading and option
lists where descriptions are provided, hence:

(gdb) set architecture s390:31-bit
(gdb) show disassembler-options
The current disassembler options are ''

The following disassembler options are supported for use with the
'set disassembler-options <option>[,<option>...]' command:

  esa         Disassemble in ESA architecture mode
  zarch       Disassemble in z/Architecture mode
  insnlength  Print unknown instructions according to length from first two bits
(gdb)

but:

(gdb) set architecture powerpc:common
(gdb) show disassembler-options
The current disassembler options are ''

The following disassembler options are supported for use with the
'set disassembler-options <option>[,<option>...]' command:
  403, 405, 440, 464, 476, 601, 603, 604, 620, 7400, 7410, 7450, 7455, 750cl,
  821, 850, 860, a2, altivec, any, booke, booke32, cell, com, e200z4, e300,
  e500, e500mc, e500mc64, e5500, e6500, e500x2, efs, efs2, power4, power5,
  power6, power7, power8, power9, ppc, ppc32, 32, ppc64, 64, ppc64bridge,
  ppcps, pwr, pwr2, pwr4, pwr5, pwr5x, pwr6, pwr7, pwr8, pwr9, pwrx, raw, spe,
  spe2, titan, vle, vsx
(gdb)

Existing affected target backends have been adjusted accordingly.

This has been verified manually with:

(gdb) set architecture arm
(gdb) set architecture powerpc:common
(gdb) set architecture s390:31-bit

to cause no issues with the `show disassembler-options' and `set
disassembler-options' commands.  A test case for the MIPS target has
also been provided, covering the default settings with ABI overrides as
well as disassembler option overrides.

c7110220be Change build_address_symbolic to return std::string 
This changes two out parameters of build_address_symbolic to be
std::string, and updates the callers.  This allows removing some
cleanups.

This patch also moves the declaration of build_address_symbolic out of
defs.h.  I think that many things in defs.h should be elsewhere
instead.  In this case, I moved the declaration to valprint.h, becuase
there is no "printcmd.h" -- but perhaps it would be better to
introduce that instead.

Tested by the buildbot.

30f0b10158 Remove cleanups from disasm.c 
This changes the remaining spots in disasm.c to use the RAII ui-out
emitters, removing a few cleanups.  This also fixes a regression that
Simon pointed out.

f1735a53a6 Rename _const functions to use overloading instead 
This renames a few functions -- skip_spaces_const,
skip_to_space_const, get_number_const, extract_arg_const -- to drop
the "_const" suffix and instead rely on overloading.

This makes future const fixes simpler by reducing the number of lines
that must be changed.  I think it is also not any less clear, as all
these functions have the same interface as their non-const versions by
design.  Furthermore there's an example of using an overload in-tree
already, namely check_for_argument.

This patch was largely created using some perl one-liners; then a few
fixes were applied by hand.

9a24775b97 Introduce gdb_disassembly_flags 
For some reason I ended up staring at some of the "int flags" in
btrace-related code, and I got confused because I had no clue what the
flags where supposed to indicate.

Fix that by using enum_flags, so that:
  #1 - it's clear from the type what the flags are about, and
  #2 - the compiler can catch mismatching mistakes

eb3ff9a551 Introduce class completion_tracker & rewrite completion<->readline interaction 
This patch reworks the whole completion machinery, and prepares it
for later enhancements.

Adds a new "completion_tracker" class that is meant to hold everything
about the state of the current completion operation.

This class now has the responsibility of tracking the list of
completion matches, and checking whether the max completions limit has
been reached.  You can look at this as this patch starting out by
C++fying the existing "completion_tracker" in symtab.c (it's just an
htab_t typedef currently), moving it to completer.h/c, and then making
it a class/generalizing/enhancing it.

Unlike with the current tracking, completion_tracker now checks
whether the limit has been reached on each completion match list
insertion.  This both simplifies the max-completions handling code
(maybe_add_completion_enum is gone, for example), and is a
prerequisite for follow up patches.

The current completion_tracker is only used for symbol completions,
and the symbol code gets at the current instance via globals.  This
patch cleans that up by adding a completion_tracker reference to the
signature of the completion functions, and passing the tracker around
everywhere necessary.

Then, the patch changes how the completion match list is handed over
to readline.  Currently, we're using the rl_completion_entry_function
readline entry point, and the patch switches to
rl_attempted_completion_function.  A following patch will want to let
GDB itself decide the common completion prefix between all matches
(what readline calls the "lowest common denominator"), instead of
having readline compute it, and that's not possible with the
rl_completion_entry_function entry point.  Also,
rl_attempted_completion_function lets GDB hand over the match list to
readline as an array in one go instead of passing down matches one by
one, so from that angle it's a nicer entry point anyway.

Lastly, the patch catches exceptions around the readline entry points,
because we can't let C++ exceptions cross readline.  We handle that in
the readline input entry point, but the completion entry point isn't
guarded, so GDB can abort if completion throws.  E.g., in current
master:

 (gdb) b -function "fun<tab>
 terminate called after throwing an instance of 'gdb_exception_RETURN_MASK_ERROR'
 Aborted (core dumped)

This patch fixes that.  This will be exercised in the new tests added
later on in the series.

This patch changes various places to use ui_out_emit_tuple,

f995bbe8e6 -Wwrite-strings: Constify struct disassemble_info's disassembler_options field 
The memory disassemble_info::disassembler_options points to is always
owned by the client.  I.e., that field is an non-owning, observing
pointer.  Thus const makes sense.

Are the include/ and opcodes/ bits OK?

Tested on x86_64 Fedora 23, built with --enable-targets=all.

65b48a8140 GDB: Add support for the new set/show disassembler-options commands. 
This commit adds support to GDB so that it can modify the disassembler-options

8b172ce7c9 Reuse buffers across gdb_pretty_print_insn calls 
gdb_pretty_print_insn allocates and destroys a couple local buffers
each time it is called, which can be many times when disassembling a
region of memory.  Avoid that overhead by adding a new class that
holds the buffers and making gdb_pretty_print_insn a method of that
class, so that the buffers can be reused across calls.

gdb/ChangeLog:
2017-02-02  Pedro Alves  <palves@redhat.com>

	* disasm.c (gdb_pretty_print_insn): Rename to ...
	(gdb_pretty_print_disassembler::pretty_print_insn): ... this.
	Remove gdbarch parameter.  Adapt to clear the object's buffers
	instead of allocating new buffers, and to print using the object's
	gdb_disassembler instead of calling gdb_print_insn.
