13572	gdb-9.2	Douglas R. Reno	Bruce Dubbs	"New minor version

{{{
GDB 9.2 brings the following fixes and enhancements over GDB 9.1:

 * PR tui/25586 (Resizing the source/disassembly or command window produces corrupted display)
 * PR gdb/25650 (GDB can't 'printf' a convenience variable holding an inferior address)
 * PR build/25981 (Use of short i386 register names breaks compilation on recent Solaris 11.4)
 * PR symtab/26003 (infinite loop loading symbols from separate debug objfile)
 * PR build/26029 (GDB build failure on SPARC)

GDB 9.1 includes the following changes and enhancements:

* Building GDB and GDBserver now requires GNU make >= 3.82.

* If you choose to build GDB without using the GNU readline version bundled
  with the GDB sources, building GDB new requires GNU readline >= 7.0.

* Removed targets and native configurations:
  - GDB no longer supports debugging the Cell Broadband Engine;
  - GDB no longer supports Solaris 10.

* New TI PRU Simulator (pru-*-elf).

* Python Enhancements:
  - GDB can now be compiled with Python 3 on Windows;
  - Various Python API enhancements;

* Usability enhancements:
  - [experimental] Multithreaded symbol loading for higher performance
    (turned off by default, use 'maint set worker-threads unlimited'
    to turn this feature on);
  - Command names can now use the '.' character;
  - GDB can now place breakpoints on nested functions and subroutines
    in Fortran;
  - GDB now shows the Ada task names at more places, e.g. in task switching
    messages.
  - Styling enhancements to various commands to improve readability.
  - GDB now has a standard infrastructure to support dash-style command
    options ('-OPT').  One benefit is that commands that use it can
    easily support completion of command line arguments. Try ""CMD
    -[TAB]"" or ""help CMD"" to find options supported by a command.  Over
    time, we intend to migrate most commands to this infrastructure.

* Enhancements to existing commands:
  - ""printf"" and ""eval"" can now print C-style and Ada-style strings
     without calling functions in the program;
  - ""info sources"" has been enhance to allow only printing files
    whose name match a REGEXP;
  - New value ""presence"" for the ""set print frame-arguments"" setting,
    to only indicate the presence of arguments with '...' instead
    of printing the argument names and values;
  - The ""focus"", ""winheight"", ""+"", ""-"", "">"", ""<"" TUI commands are
    now case sensitive;
  - New options support for the following commands that allow overriding
    a number of relevant global settings (as set by e.g. ""set print
    [...]"" commands): ""print"", ""compile print"", ""backtrace"", ""frame
    apply"", ""tfaas"", ""faas"";
  - ""info types"" support for ""-q"" to disable printing of some header
    information;
  - In settings, ""unlimited"" can now be abbreviated with ""u"".

* New commands:
  - ""define-prefix"" to define user-defined prefix commands;
  - ""|"" or ""pipe"" to execute a command and send its output to
    a shell command.
  - ""with"" to run a given command with a setting temporarily changed
    to a given value;
  - ""set may-call-functions"" to control whether subprogram can be
    called from GDB;
  - ""set print finish [on|off]"" to control whether the returned value
    should be printed when using the ""finish"" command;
  - ""set print max-depth"" to simplify the printing of deeply nested
    structures;
  - ""set print raw-values [on|off]"" to turn on and off pretty printers;
  - ""set logging debugredirect [on|off]"" to control whether to redirect
    debug output to the log file;
  - Various new ""set style"" commands;
  - ""set print frame-info [...]"" to control what information to print
    when printing a frame.
  - ""set tui compact-source"" to enable the ""compact"" mode for the TUI
    source window;
  - ""info modules [...]"" to query information about Fortran modules;
  - The ""set/show print raw-frame-arguments"" commands replace
    the ""set/show print raw frame-arguments"" (now with a dash instead of
    a space). The latter is now deprecated and may be removed in
    a future release.

* New GDB/MI commands
  - ""-complete"" to list possible completions;
  - ""-catch-throw"", ""-catch-rethrow"", and ""-catch-catch"", the GDB/MI
    equivalent of the ""catch throw"", ""catch rethrow"", and ""catch catch""
    commands (respectively);
  - ""-symbol-info-functions"", ""-symbol-info-types"", and
    ""-symbol-info-variables"", the GDB/MI equivalent of the ""info functions"",
    ""info types"", and ""info variables"" commands (respectively);
  - ""-symbol-info-modules"", ""-symbol-info-module-functions"",
    and ""-symbol-info-module-variables"", the GDB/MI equivalent of
    ""info modules"", ""info module functions"" and ""info module variables"".

* Other MI changes
  - The default version of the MI interpreter is now 3 (-i=mi3);
  - The output of information about multi-location breakpoints (which is
    syntactically incorrect in MI 2) has changed in MI 3;
  - Backtraces and frames include a new optional field ""addr_flags"".

* Several new builtin convenience variables
  - $_gdb_major and $_gdb_minor;
  - $_gdb_setting, $_gdb_setting_str, $_gdb_maint_setting and
    $_gdb_maint_setting_str
  - $_cimag and $_creal
  - $_shell_exitcode and $_shell_exitsignal

* Miscellaneous enhancements:
  - Support for a new configure option ""--with-system-gdbinit-dir"",
    where system gdbinit files are to be loaded from at startup;
  - 'thread-exited' event is now available in the annotations interface;
  - The TUI SingleKey keymap is now named ""SingleKey"" (requires
    GNU readline >= 8.0).
