This patch adds two new commands "info module functions" and "info module variables". These commands list all of the functions and variables grouped by module and then by file. For example: (gdb) info module functions All functions in all modules: Module "mod1": File /some/path/gdb/testsuite/gdb.fortran/info-types.f90: 35: void mod1::__copy_mod1_M1t1(Type m1t1, Type m1t1); 25: void mod1::sub_m1_a(integer(kind=4)); 31: integer(kind=4) mod1::sub_m1_b(void); Module "mod2": File /some/path/gdb/testsuite/gdb.fortran/info-types.f90: 41: void mod2::sub_m2_a(integer(kind=4), logical(kind=4)); 49: logical(kind=4) mod2::sub_m2_b(real(kind=4)); The new commands take set of flags that allow the output to be filtered, the user can filter by variable/function name, type, or containing module. As GDB doesn't currently track the relationship between a module and the variables or functions within it in the symbol table, so I filter based on the module prefix in order to find the functions or variables in each module. What this makes clear is that a user could get this same information using "info variables" and simply provide the prefix themselves, for example: (gdb) info module functions -m mod1 _a All functions matching regular expression "_a", in all modules matching regular expression "mod1": Module "mod1": File /some/path/gdb/testsuite/gdb.fortran/info-types.f90: 25: void mod1::sub_m1_a(integer(kind=4)); Is similar to: (gdb) info functions mod1::.*_a.* All functions matching regular expression "mod1::.*_a": File /some/path/gdb/testsuite/gdb.fortran/info-types.f90: 25: void mod1::sub_m1_a(integer(kind=4)); The benefits I see for a separate command are that the user doesn't have to think (or know) about the module prefix format, nor worry about building a proper regexp. The user can also easily scan across modules without having to build complex regexps. The new function search_module_symbols is extern in this patch despite only being used within symtab.c, this is because a later patch in this series will also be using this function from outside symtab.c. This patch is a new implementation of an idea originally worked on by Mark O'Connor, Chris January, David Lecomber, and Xavier Oro from ARM. gdb/ChangeLog: * symtab.c (info_module_cmdlist): New variable.

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.
