New settings allow to better control what frame information is printed. 'set print frame-info' allows to override the default frame information printed when a GDB command prints a frame. The backtrace command has a new option -frame-info to override this global setting. It is now possible to have very short frame information by using the new 'set print frame-arguments presence' and 'set print frame-info short-location'. Combined with 'set print address off', a backtrace will only show the essential information to see the function call chain, e.g.: (gdb) set print address off (gdb) set print frame-arguments presence (gdb) set print frame-info short-location (gdb) bt #0 break_me () #1 call_me (...) #2 main () (gdb) This is handy in particular for big backtraces with functions having many arguments. Python frame filter printing logic has been updated to respect the new setting in non MI mode. Also, the default frame information printed was inconsistent when backtrace was printing the frame information itself, or when the python frame filtering code was printing the frame information. This patch changes the default of python frame filtering to have a consistent behaviour regarding printed frame-information, whatever the presence/activity/matches of python filters. 2019-07-29 Philippe Waroquiers <philippe.waroquiers@skynet.be> * frame.h (enum print_what): New value 'SHORT_LOCATION', update comments. (print_frame_info_auto, print_frame_info_source_line, print_frame_info_location, print_frame_info_source_and_location, print_frame_info_location_and_address, print_frame_info_short_location): New declarations. (struct frame_print_options): New member print_frame_info. * extension.h (enum ext_lang_frame_args): New value CLI_PRESENCE. * stack.h (get_user_print_what_frame_info): New declaration. (frame_show_address): New declaration. * stack.c (print_frame_arguments_choices): New value 'presence'. (print_frame_info_auto, print_frame_info_source_line, print_frame_info_location, print_frame_info_source_and_location, print_frame_info_location_and_address, print_frame_info_short_location, print_frame_info_choices, print_frame_info_print_what): New definitions. (print_frame_args): Only print dots for args if print frame-arguments is 'presence'. (frame_print_option_defs): New element for "frame-info". (get_user_print_what_frame_info): New function. (frame_show_address): Make non static. Move comment to stack.h. (print_frame_info_to_print_what): New function. (print_frame_info): Update comment. Use fp_opts.print_frame_info to decide what to print. (backtrace_command_1): Handle the new print_frame_arguments_presence value. (_initialize_stack): Call add_setshow_enum_cmd for frame-info. * python/py-framefilter.c (py_print_args): Handle CLI_PRESENCE. (py_print_frame): In non-mi mode, use LOCATION as default for print_what, similarly to frame information printed directly by backtrace command. Handle frame-info user option in non MI mode. |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
