Looking at `cooked_index_shard::find`, I thought that we could make a small optimization: when finding the upper bound, we already know the lower bound. And we know that the upper bound is >= the lower bound. So we could pass `lower` as the first argument of the `std::upper_bound` call to cut the part of the search space that is below `lower`. It then occured to me that what we do is basically what `std::equal_range` is for, so why not use it. Implementations of `std::equal_range` are likely do to things as efficiently as possible. Unfortunately, because `cooked_index_entry::compare` is sensitive to the order of its parameters, we need to provide two different comparison functions (just like we do know, to the lower_bound and upper_bound calls). But I think that the use of equal_range makes it clear what the intent of the code is. Regression tested using the various DWARF target boards on Debian 12.

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.
