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).
