The type struct compunit_symtab contains two fields (disregarding field next)
that express relations with other compunit_symtabs: user and includes.
These fields are currently not printed with "maint info symtabs" and
"maint print symbols".
Fix this such that for "maint info symtabs" we print:
...
{ ((struct compunit_symtab *) 0x23e8450)
debugformat DWARF 2
producer (null)
dirname (null)
blockvector ((struct blockvector *) 0x23e8590)
+ user ((struct compunit_symtab *) 0x2336280)
+ ( includes
+ ((struct compunit_symtab *) 0x23e85e0)
+ ((struct compunit_symtab *) 0x23e8960)
+ )
{ symtab <unknown> ((struct symtab *) 0x23e85b0)
fullname (null)
linetable ((struct linetable *) 0x0)
}
}
...
And for "maint print symbols" we print:
...
-Symtab for file <unknown>
+Symtab for file <unknown> at 0x23e85b0
Read from object file /data/gdb_versions/devel/a.out (0x233ccf0)
Language: c
Blockvector:
block #000, object at 0x23e8530, 0 syms/buckets in 0x0..0x0
block #001, object at 0x23e84d0 under 0x23e8530, 0 syms/buckets in 0x0..0x0
+Compunit user: 0x2336300
+Compunit include: 0x23e8900
+Compunit include: 0x23dd970
...
Note: for user and includes we don't list the actual compunit_symtab address,
but instead the corresponding symtab address, which allows us to find that
symtab elsewhere in the output (given that we also now print the address of
symtabs).
gdb/ChangeLog:
2020-03-25 Tom de Vries <tdevries@suse.de>
* symtab.h (is_main_symtab_of_compunit_symtab): New function.
* symmisc.c (dump_symtab_1): Print user and includes fields.
(maintenance_info_symtabs): Same.
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.
