The dwarf2_psymtab and dwarf2_per_cu_quick_data types contain a pointer to a compunit_symtab, which is a pointer to the corresponding full symtab. The dwarf2_psymtab and dwarf2_per_cu_quick_data objects are going to become objfile-independent, and possibly shared by multiple objfiles, whereas compunit_symtab will stay objfile-dependent. This backlink to the compunit_symtab must therefore be removed. This patch replaces them with a vector in the dwarf2_per_objfile type, that serves as a mapping from dwarf2_per_cu_data objects to compunit_symtab objects, for this particular objfile. The vector is indexed using the index assigned to the dwarf2_per_cu_data at its creation. I removed the get_compunit_symtab, as it appears to bring not much value over calling dwarf2_per_objfile::get_symtab directly. gdb/ChangeLog: YYYY-MM-DD Tom Tromey <tom@tromey.com> YYYY-MM-DD Simon Marchi <simon.marchi@efficios.com> * dwarf2/read.h (struct dwarf2_per_bfd) <num_psymtabs>: New method.

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.
