The option framework documentation was speaking about a 'print -raw'
option, but this option does not exist.
This patch implements -raw-values option that tells to ignore the
active pretty printers when printing a value.
As we already have -raw-frame-arguments, I thought -raw-values
was more clear, in particular to differentiate
set print raw-values and set print raw-frame-arguments.
gdb/doc/ChangeLog
2019-12-11 Philippe Waroquiers <philippe.waroquiers@skynet.be>
* gdb.texinfo (Command Options): Use -p and -pretty in the example,
as -r is ambiguous. Update the print - TAB TAB completion result.
(Data): Document new option -raw-values. Use -p and -pretty in the
example, as -r is ambiguous.
(Print Settings): Document set print raw values.
(Pretty-Printer Commands): Document interaction between enabled
pretty printers and -raw-values/-raw-frame-arguments.
gdb/ChangeLog
2019-12-11 Philippe Waroquiers <philippe.waroquiers@skynet.be>
* NEWS: Document -raw-values option and the related setting commands.
* printcmd.c (print_command_parse_format): Do not set opts->raw off,
only set it on when /r is given.
* valprint.c (value_print_option_defs): New element raw-values.
* Makefile.in: Add the new file.

* gdb.base/options.exp: Add -raw-values in the print completion list.
* gdb.python/py-prettyprint.exp: Add tests for -raw-values.

The default max-depth is 20, but this can be set to unlimited to get
the old behavior back.
+set print raw-values [on|off]
+show print raw-values
+ By default, GDB applies the enabled pretty printers when printing a
+ value. This allows to ignore the enabled pretty printers for a series
+ of commands. The default is 'off'.
+
set logging debugredirect [on|off]
By default, GDB debug output will go to both the terminal and the logfile.
Set if you want debug output to go only to the log file.

-object [on|off]
-pretty [on|off]
+ -raw-values [on|off]
-repeats NUMBER|unlimited
-static-members [on|off]

"on" if omitted. This allows writing compact command invocations,
like for example:
- (gdb) p -r -p -o 0 -- *myptr
+ (gdb) p -ra -p -o 0 -- *myptr
The above is equivalent to:
- (gdb) print -raw -pretty -object off -- *myptr
+ (gdb) print -raw-values -pretty -object off -- *myptr
** The "info types" command now supports the '-q' flag to disable
printing of some header information in a similar fashion to "info
