The "help" command can output long list of command names or classes.
Use the title style to style the command names or classes to make
the output more readable.
Similarly, change "apropos" command to also style the command names.
It is sometimes unclear why "apropos REGEXP" lists some commands,
and then the user has to manually do 'help command' for all commands
listed by "apropos" to see more details about the matching commands.
=> Add an optional flag -v so that "apropos -v REGEXP":
* outputs the full documentation of matching commands.
* highlights the documentation parts matching REGEXP.
Have 'show style' and its subcommands using a style to style its output.
This allows the GDB user or developer to use 'show style' to visually see
with one command how all the current styles look like.
Add 2 new styles highlight style, title style and fputs_highlighted function.
Highlight style is used by fputs_highlighted to highlight the parts of
its char *STR argument that match a HIGHLIGHT regexp.
This (and the title style) will be used in a following patch.

* gdb.base/shell.exp: Test pipe command, $_shell_exitcode,
$_shell_exitsignal.
* gdb.base/default.exp: Update for new convenience variables.
The pipe command allows to run a GDB command, and pipe its output
to a shell command:
(gdb) help pipe
Send the output of a gdb command to a shell command.
Usage: | [COMMAND] | SHELL_COMMAND
Usage: | -d DELIM COMMAND DELIM SHELL_COMMAND
Usage: pipe [COMMAND] | SHELL_COMMAND
Usage: pipe -d DELIM COMMAND DELIM SHELL_COMMAND
Executes COMMAND and sends its output to SHELL_COMMAND.
The -d option indicates to use the string DELIM to separate COMMAND
from SHELL_COMMAND, in alternative to |. This is useful in
case COMMAND contains a | character.
With no COMMAND, repeat the last executed command
and send its output to SHELL_COMMAND.
(gdb)
For example:
(gdb) pipe print some_data_structure | grep -B3 -A3 something
The pipe character is defined as an alias for pipe command, so that
the above can be typed as:
(gdb) | print some_data_structure | grep -B3 -A3 something
If no GDB COMMAND is given, then the previous command is relaunched,
and its output is sent to the given SHELL_COMMAND.
This also defines convenience vars $_shell_exitcode and $_shell_exitsignal
to record the exit code and exit signal of the last shell command
launched by GDB e.g. by "shell", "pipe", ...

Currently, a previous command can be repeated when the user types an
empty line. This is implemented in handle_line_of_input by
returning saved_command_line in case an empty line has been input.
If we want a command to repeat the previous command, we need to save
the previous saved_command_line, as when a command runs, the saved_command_line
already contains the current command line of the command being executed.
As suggested by Tom, the previous_saved_command_line is made static.
At the same time, saved_command_line is also made static.
The support functions/variables for the repeat command logic are now all
located inside top.c.

- Use of nonportable <endian.h>
- Use of qsort_r
- Use of zlib without appropriate magic to pull in the binutils zlib
- Use of off64_t without checking (fixed by dropping the unused fields
that need off64_t entirely)
- signedness problems due to long being too short a type on 32-bit
platforms: ctf_id_t is now 'unsigned long', and CTF_ERR must be
used only for functions that return ctf_id_t
- One lingering use of bzero() and of <sys/errno.h>

On commit 7bede82892 ("Don't crash if
dwarf_decode_macro_bytes's 'body' is NULL"), I was too strict when
checking if 'body' is NULL: the check only comprised the case when
'is_define' is true. However, the corruption of .debug_macro by
rpmbuild's "debugedit" also affects the case when 'is_define' is
false, i.e., when the macro is being undefined.
This commit improves the check and covers both cases now. This has
been tested on Fedora 30 with a problematic debuginfo, and I don't see
a segfault anymore.
OK to push?

PR c++/20020 concerns a crash in cp_print_value_fields. The immediate
cause is that cp_print_value_fields does not handle the case where
value_static_field fails. This is fixed in this patch by calling
cp_print_static_field from the "try" block.
Digging a bit deeper, the error occurs because GCC does not emit a
DW_AT_const_value for a static constexpr member appearing in a
template class. I've filed a GCC bug for this.

A user wanted to be able to disable the display of the value when
using "finish" -- but still have the value entered into the value
history in case it was useful later on. Part of the rationale here is
that sometimes the value might be quite large, or expensive to display
(in their case this was compounded by a rogue pretty-printer).
This patch implements this idea.

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.

This introduces CTF support for objdump and readelf. objdump has the
following new arguments:
--ctf=SECTION: display CTF in the given SECTION
--ctf-parent=SECTION: name of CTF section that is the parent of this section
readelf has the above, and these two as well:
--ctf-symbols=SECTION: name of symbol table section (optional)
--ctf-strings=SECTION: name of string table section (optional)
(objdump can always use BFD machinery to determine the applicable string
and symbol tables automatically, so these arguments are unnecessary.)
Nearly all the work is done by the ctf_dump machinery in libctf: most of
the remaining work is option-processing and section-reading, and thus is
different for objdump and readelf: the minimal amount of similar code
remaining is, in my view, too small to share, particularly given that
objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it
doesn't have a bfd.
I am not particularly satisfied with the way resources are freed in
either of these (I was forced to do it at the top level, for lack of
anywhere else to free resources allocated during option processing), but
I can't see any better way to do it without introducing new
infrastructure for no other purpose.
There are essentially arbitrary ordering changes to the Makefile.in's
order of libtool-related stuff that I can't get rid of, but they have no
semantic effect. (It is possible that some hunks of these changes could
be dropped, but that seems a bit risky to me.)

* configure: Likewise.
This introduces ctf_dump(), an iterator which returns a series of
strings, each representing a debugging dump of one item from a given
section in the CTF file. The items may be multiline: a callback is
provided to allow the caller to decorate each line as they desire before
the line is returned.

This facility allows you to associate regions of type IDs with *labels*,
a labelled tiling of the type ID space. You can use these to define
CTF containers with distinct parents for distinct ranges of the ID
space, or to assist with parallelization of CTF processing, or for any
other purpose you can think of.
Notably absent from here (though declared in the API header) is any way
to define new labels: this will probably be introduced soon, as part of
the linker deduplication work. (One existed in the past, but was deeply
tied to the Solaris CTF file generator and had to be torn out.)
libctf/
* ctf-labels.c: New.

This old Solaris standard allows callers to specify that they are
expecting one particular API and/or CTF file format from the library.

* ctf-subr.c (_libctf_version): Define it.
