This patch tries to standardize the places where we check if units are
dummy. When checking if a unit is dummy, it is not necessary to check
for some other conditions.
- cutu_reader::is_dummy() is a superset of cutu_reader::cu() returning
nullptr, so it's not necessary to check if the cu method return
nullptr if also checking if the unit is dummy.
- cutu_reader::is_dummy() is a superset of cutu_reader::top_level_die()
returning nullptr, so same deal.
Remove some spots that check for these conditions in addition to
cutu_reader::is_dummy().
In addition, also remove the checks for:
!new_reader->top_level_die ()->has_children
in cooked_indexer::ensure_cu_exists. IMO, it is not useful to special
case the units having a single DIE. Especially in this function, which
deals with importing things from another unit, a unit with a single DIE
would be an edge case that should not happen with good debug info. I
think it's preferable to have simpler code.

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.
