Tom Tromey 9d636d67e0 Use styled_string in more places 
This adds more uses of styled_string, changing gdb to style some
output that was previously left unstyled.

Tom Tromey 7f6aba03b9 Introduce metadata style 
This introduces a new "metadata" style and changes many places in gdb
to use it.  The idea here is to let the user distinguish gdb output
from output that (conceptually at least) comes directly from the
inferior.  The newly-styled category includes text that gdb
traditionally surrounds in "<...>", like "<unavailable>".

I only added a single test for this.  In many cases this output is
difficult to test.  Also, while developing this errors in the
implementation of the new printf formats showed up as regressions.

Tom Tromey 4e962e74e4 Handle biased types 
In Ada, the programmer can request that a range type with a non-zero
base be stored in the minimal number of bits required for the range.
This is done by biasing the values; so, for example, a range of -7..-4
may be stored as two bits with a bias of -7.

This patch implements this for gdb.  It is done by adding a bias to
struct range_bounds and then adjusting a few spots to handle this.

The test case is written to use -fgnat-encodings=minimal, but a future
compiler patch will change the compiler to emit DW_AT_GNU_bias with
-fgnat-encodings=gdb.  It seemed good to get the gdb patch in first.

Tested on x86-64 Fedora 29; plus a variety of targets using AdaCore's
internal test suite.

Tom Tromey 272560b577 Fix bug with character enumeration literal 
gnat encodes character enumeration literals using a few different
schemes.  The gnat compiler documented the "QU" and "QW" encodings,
but failed to document that a simpler encoding was used for certain
characters.

This patch updates gdb to handle this simple Q encoding.  Note that
wide character literals are still not handled.

Philippe Waroquiers 590042fc45 Make first and last lines of 'command help documentation' consistent. 
With this patch, the help docs now respect 2 invariants:
  * The first line of a command help is terminated by a '.' character.
  * The last character of a command help is not a newline character.

Note that the changes for the last invariant were done by Tom, as part of :
 [PATCH] Remove trailing newlines from help text
 https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html
but some occurrences have been re-introduced since then.

Some help docs had to be rephrased/restructured to respect the above
invariants.

Before this patch, print_doc_line was printing the first line
of a command help documentation, but stopping at the first '.'
or ',' character.

This was giving inconsistent results :
  * The first line of command helps was sometimes '.' terminated,
    sometimes not.
  * The first line of command helps was not always designed to be
    readable/understandable/unambiguous when stopping at the first
    '.' or ',' character.

This e.g. created the following inconsistencies/problems:
< catch exception -- Catch Ada exceptions
< catch handlers -- Catch Ada exceptions
< catch syscall -- Catch system calls by their names
< down-silently -- Same as the `down' command
while the new help is:
> catch exception -- Catch Ada exceptions, when raised.
> catch handlers -- Catch Ada exceptions, when handled.
> catch syscall -- Catch system calls by their names, groups and/or numbers.
> down-silently -- Same as the `down' command, but does not print anything.

Also, the command help doc should not be terminated by a newline
character, but this was not respected by all commands.
The cli-option -OPT framework re-introduced some occurences.
So, the -OPT build help framework was changed to not output newlines at the
end of %OPTIONS% replacement.

This patch changes the help documentations to ensure the 2 invariants
given above.

It implied to slightly rephrase or restructure some help docs.

Based on the above invariants, print_doc_line (called by
'apropos' and 'help' commands to print the first line of a command
help) now outputs the full first line of a command help.

This all results in a lot of small changes in the produced help docs.
There are less code changes than changes in the help docs, as a lot
of docs are produced by some code (e.g. the remote packet usage settings).

Tom Tromey 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.

Tom Tromey 680e1beed3 Fix crash when setting breakpoint condition 
gdb could crash when setting a breakpoint condition on a breakpoint
when using the Ada language.  The problem occurred because the
ada_evaluate_subexp would try to evaluate the array to compute its
attributes, but evaluating can't really be done at this time.

This patch fixes the problem by arranging not to try to evaluate in
EVAL_AVOID_SIDE_EFFECTS mode when computing an attribute.

Tested on x86-64 Fedora 29.  Because this is Ada-specific, and because
Joel approved it internally, I am checking it in.

Tom Tromey f411722cbc Allow re-assigning to convenience variables 
In Ada mode, re-assigning an array of a different size to a
convenience variable will cause an error:

    (gdb) set lang ada

Pedro Alves b02f78f928 Introduce and use make_unique_xstrdup 
Adds an utility function to make it shorter to write the common case
of wrapping an xstrdup with a unique_xmalloc_ptr, and uses it
throughout.

Note: I tried to put this in common/common-utils.h near skip_spaces,
etc. but that is included in common/common-defs.h before
common/gdb_unique_ptr.h is included, so it would fail to compile
because gdb::unique_xmalloc_ptr isn't defined at that point yet.  I
tried moving the gdb_unique_ptr.h inclusion before common-utils.h, but
that doesn't work because gdb_unique_ptr.h depends on common-utils.h
for xfree.

Tom Tromey c0e70c624f Remove find_old_style_renaming_symbol 
We found a case where a "bt" was very slow with Ada code.  Profiling
with callgrind showed this to be primarily due to calls to
find_old_style_renaming_symbol.  Because new-style renaming symbols
were implemented in 2007, it seems safe enough to remove this old
code.

A "-batch -ex bt" test on a large Ada program improves from:

    13.23user 0.57system 0:13.82elapsed 99%CPU (0avgtext+0avgdata 571408maxresident)k

Tom Tromey c408a94f81 Fix assertion failure in coerce_unspec_val_to_type 
coerce_unspec_val_to_type does:

However, this is only valid for lval_memory.  This patch changes this

Tom Tromey 2ff0a94739 Fix "catch exception" with dynamic linking 
When an Ada program is dynamically linked against libgnat, and when
one of the standard exceptions is used, the exception object may be
referenced by the main executable using a copy relocation.

In this situation, a "catch exception" for those exceptions will not
manage to stop.  This happens because, under the hood, "catch
exception" creates an expression object that examines the object
addresses -- but in this case, the address will be incorrect.

This patch fixes the problem by arranging for these filter expressions
to examine all the relevant minimal symbols.  This way, the object
from libgnat will be found as well.

Andrew Burgess 4be290b251 gdb: Introduce new language field la_is_string_type_p 
This commit is preparation work for the next commit, and by itself
makes no user visible change to GDB.  I've split this work into a
separate commit in order to make code review easier.

This commit adds a new field 'la_is_string_type_p' to the language
struct, this predicate will return true if a type is a string type for
the given language.

Some languages already have a "is this a string" predicate that I was
able to reuse, while for other languages I've had to add a new
predicate.  In this case I took inspiration from the value printing
code for that language - what different conditions would result in
printing something as a string.

A default "is this a string" method has also been added that looks for
TYPE_CODE_STRING, this is the fallback I've used for a couple of
languages.

In this commit I add the new field and initialise it for each
language, however at this stage the new field is never used.

Andrew Burgess fc913e53c3 gdb/ada: Update some predicate functions to return bool 
A later commit would like to make use of a pointer to the function
ada_is_string_type, however, this will require the function to return
a bool (so the signature matches).

As the ada_is_string_type is a predicate function, and its return
value is only ever used as either true or false, then this commit
updates the function to return a bool.

As a consequence ada_is_character_type needs to change too.

There should be no user visible changes after this commit.

Tom Tromey 8ecb59f856 Print non-Ada unions without crashing 
ada-lang.c is a bit too eager trying to decode unions in the Ada style
-- looking for discriminants and such.  This causes crashes when
printing a non-Ada union in Ada mode, something that can easily happen
when printing a value from history or certain registers on AArch64.

This patch fixes the bug by changing ada-lang.c to only apply special
Ada treatment to types coming from an Ada CU.  This in turn required a
couple of surprising changes.

First, some of the Ada code was already using HAVE_GNAT_AUX_INFO to
decide whether a type had already been fixed -- such types had
INIT_CPLUS_SPECIFIC called on them.  This patch changes these spots to
use the "none" identifier instead.

This then required changing value_rtti_type to avoid changing the
language-specific object attached to an Ada type, which seems like a
good change regardless.

Tested on x86-64 Fedora 29.

Andrew Burgess 62253a6147 gdb: Remove LANG_MAGIC 
The language_defn structure has an la_magic field, this used to be
used as a basic check that the language_defn structure had the
expected layout - at least the end of the structure was where we
expected it to be.

This feature only really makes sense if we imagine GDB dynamically
loading language support from dynamic libraries, where a version
mismatch might cause problems.

However, in current GDB language support is statically built into GDB,
and since this commit:

    commit 47e77640be
    Date:   Thu Jul 20 18:28:01 2017 +0100

        Make language_def O(1)

the existing (if pointless) check of the la_magic field was removed.

There now appears to be no use of the la_magic field, and I propose
that we delete it.

There should be no user visible changes after this commit.

Tom Tromey 230d2906b9 Rename gdb exception types 
This renames the gdb exception types.  The old types were only needed
due to the macros in common-exception.h that are now gone.

The intermediate layer of gdb_exception_RETURN_MASK_ALL did not seem
needed, so this patch removes it entirely.

Tom Tromey 3d6e9d2336 Make exceptions use std::string and be self-managing 
This changes the exception's "message" member to be a shared_ptr
wrapping a std::string.  This allows removing the stack of exception
messages, because now exceptions will self-destruct when needed.  This
also adds a noexcept copy constructor and operator= to gdb_exception,
plus a "what" method.

Tom Tromey 699bd4cfa8 Move innermost_block_tracker global to parse_state 
This changes the parsing API so that callers that are interested in
tracking the innermost block must instantiate an
innermost_block_tracker and pass it in.  Then, a pointer to this
object is stored in the parser_state.

Keith Seitz cc1defb1dc Allow really large fortran array bounds: TYPE_LENGTH to ULONGEST 
This series is revisit of Siddhesh Poyarekar's patch from back in
2012. The last status on the patch is in the following gdb-patches
thread:

  https://sourceware.org/ml/gdb-patches/2012-08/msg00562.html

It appears that Tom approved the patch, but Jan had some issues
with a compiler error that made the test fail on -m32 test runs.
He wrote up a hand-tweaked .S file to deal with it. Siddesh said
he would update tests. Then nothing.

Siddesh and Jan have both moved on since.

The patch originally required a large precursor patch to work.
I have whittled this down to/rewritten the bare minimum, and this
first patch is the result, changing the type of TYPE_LENGTH
to ULONGEST from unsigned int.

The majority of the changes involve changing printf format
strings to use %s and pulongest instead of %d.

gdb/ChangeLog:

	* ada-lang.c (ada_template_to_fixed_record_type_1): Use
	%s/pulongest for TYPE_LENGTH instead of %d in format
	strings.
	* ada-typerint.c (ada_print_type): Likewise.
	* amd64-windows-tdep.c (amd64_windows_store_arg_in_reg): Likewise.

	* m2-typeprint.c (m2_array):  Use %s/pulongest for TYPE_LENGTH
	instead of %d in format strings.
	* riscv-tdep.c (riscv_type_alignment): Cast second argument
	to std::min to ULONGEST.
	* symmisc.c (print_symbol): Use %s/pulongest for TYPE_LENGTH
	instead of %d in format strings.
	* tracepoint.c (info_scope_command): Likewise.

Tom Tromey 6640a367bf Remove null_block_symbol 
This removes null_block_symbol.  It seemed simpler to me to change
initializations and returns to use value initialization rather than
null_block_symbol.  This also fixes up a few spots where
initialization was done piecemeal.

Tom Tromey 582942f456 More block constification 
I noticed that there are still many places referring to non-const
blocks.  This constifies all the remaining ones that I found that
could be constified.

In a few spots, this search found unused variables or fields.  I
removed these.  I've also removed some unnecessary casts to
"struct block *".

Tom Tromey bff8c71fd8 Fix Ada "ptype" bug with array types 
Using ptype on an array type in Ada can sometimes show an incorrect
high bound.  This happens because ada_evaluate_subexp will create an
array with an incorrect upper bound in the EVAL_AVOID_SIDE_EFFECTS
case.

This patch fixes the problem by arranging to always create such an
array with valid bounds.

Tested on x86-64 Fedora 29.

Tom Tromey a008792038 Fix pager bugs with style output 
I believe this fixes all the pager output problems with styling that
Philippe pointed out, plus at least one more.  The patch is somewhat
hard to reason about, so you may wish to give it a try.  Even writing
the tests was hard.

This removes the style caching, because it was difficult to keep the
style cache correct in all cases.  Since this would cause more style
escapes to be emitted, instead it changes fputs_styled to try to avoid
unnecessary changes.

Another bug was that the wrap buffer was not flushed in the case where
wrap_column==0.  In the old (pre-patch series) code, characters were
directly emitted in this case; so flushing the wrap buffer here
restores this behavior.

On error the wrap buffer must be emptied.  Otherwise, interrupting
output can leave characters in the buffer that will be emitted later.

As discussed on gdb-patches, this fixes the ada-lang.c problem where
filtered and unfiltered printing were mixed.  Now user_select_syms
uses filtered printing, which is what its callees were already doing.

Finally, it was possible for source line highlighting to be garbled
(and invalid escape sequences emitted) if the pager was invoked at the
wrong spot.  To fix this, the patch arranges for source line escapes
to always be emitted as a unit.

Joel Brobecker a2cd4f1475 (Ada) fix GDB crash printing packed array 
Trying to print a packed array sometimes leads to a crash (see
attached testcase for an example of when this happens):

  | (gdb) p bad
  | [1]    65571 segmentation fault  gdb -q foo

Variable "bad" is declared in the debug information as an array where
the array's type name has an XPnnn suffix:

  | .uleb128 0xc    # (DIE (0x566) DW_TAG_typedef)
  | .long   .LASF200        # DW_AT_name: "pck__t___XP1"
  | [loc info attributes snipped]
  | .long   0x550   # DW_AT_type
  | .byte   0x1     # DW_AT_alignment

The signals to GDB that the debugging information follows a GNAT encoding
used for packed arrays, and an in order to decode it, we need to find
the type whose name is the same minus the "___XPnnn" suffix: "pck__t".

For that, we make a call to ada-lang.c::standard_lookup, which is
a simple function which essentially does:

  | /* Return the result of a standard (literal, C-like) lookup of NAME in
  |    given DOMAIN, visible from lexical block BLOCK.  */
  |
  |   [...]
  |   sym = lookup_symbol_in_language (name, block, domain, language_c, 0);

Unfortunately for us, while the intent of this call was to perform
an exact-match lookup, in our case, it returns ... type pck__t___XP1
instead! In other words, it finds itself back. The reason why it finds
this type is a confluence of two factors:

  (1) Forcing the lookup into language_c currently does not affect
      how symbol matching is done anymore, because we look at the symbol's
      language to determine which kind of matching should be done;

  (2) The lookup searches the local context (via block) first, beforei
      doing a more general lookup. And looking at the debug info for
      the main subprogram, we see that type "pck__t" is not declared
      there, only in the debug info for pck.ads. In other words,
      there is no way that we accidently find "pck__t" by random chance.

I believe Pedro added a new function called ada_lookup_encoded_symbol
for that specific purpose, so I started by replacing the lookup
by language above by this. Unfortunately, still no joy.

This was because, even though ada_lookup_encoded_symbol puts angle-
brackets around the search name to signal that we want a verbatim
search, we end up losing that information in the function called
to compare a symbol with the search name:

  | static bool
  | do_full_match (const char *symbol_search_name,
  |                const lookup_name_info &lookup_name,
  |                completion_match_result *comp_match_res)
  | {
  |   return full_match (symbol_search_name, ada_lookup_name (lookup_name));
                                             ^^^^^^^^^^^^^^^
                                                    |
                                    <=> lookup_name.m_ada.m_encoded_name
                                           (no angle brackets)

The way I fixed this was by introducing a new function called
do_exact_match, and then adjust ada_get_symbol_name_matcher to
return that function when seeing that we have a verbatim non-wild-match
search.

As it happens, this fixes an incorrect test in gdb.ada/homony.exp,
where we were inserting a breakpoint on a symbol using the angle-brackets
notation, and got 2 locations for that breakpoint...

    (gdb) b <homonym__get_value>
    Breakpoint 1 at 0x4029fc: <homonym__get_value>. (2 locations)

...  each location being in a different function:

    (gdb) info break
    Num     Type           Disp Enb Address            What
    1       breakpoint     keep y   <MULTIPLE>
    1.1                         y   0x00000000004029fc in homonym.get_value
                                    at /[...]/homonym.adb:32
    1.2                         y   0x0000000000402a3a in homonym.get_value
                                    at /[...]/homonym.adb:50
    (gdb) x /i 0x00000000004029fc
       0x4029fc <homonym__get_value+8>:     movl   $0x1d,-0x4(%rbp)
    (gdb) x /i 0x0000000000402a3a
       0x402a3a <homonym__get_value__2+8>:  movl   $0x11,-0x4(%rbp)

Since we used angle-brackets, we shouldn't be matching the second one,
something this patch fixes.
