The cutu_reader type is used for reading the CU represented by the passed dwarf2_per_cu_data object. This reading is done in the context of a given obfile, which is currently the one associated to the passed dwarf2_per_cu_data object. Since the dwarf2_per_cu_data type will become objfile-independent, we will need to pass the objfile separately. This patch therefore adds a dwarf2_per_objfile parameter to the cutu_reader constructors, as well as to their callers, up until the point where we can get the dwarf2_per_objfile object from somewhere else. In the end, this allows removing the reference to dwarf2_per_cu_data::dwarf2_per_objfile in cutu_reader::cutu_reader. A few dwarf2_per_cu_data::dwarf2_per_objfile references are added (e.g. in dwarf2_fetch_die_type_sect_off). This is temporary, this will be removed once these functions will get re-worked in subsequent patches. gdb/ChangeLog: * dwarf2/read.c (class cutu_reader) <cutu_reader>: Add per_objfile parameter.

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.
