Profiling GDB with the rest of series applied, I saw calls to language_def showing up high in some runs. The problem is that language_def is O(N) currently, since walk the languages vector each time to find the matching language_defn. IMO, the add_language mechanism is pointless, because "enum language" implies the core of GDB needs to know about all languages anyway. So simply make the languages vector array be an array where each element's index is the corresponding enum language enumerator. Note that "local_language_defn" is gone along the way. It's just a copy of "auto", so the new code simply maps one to the other. One fewer place to update when we need to change the language vector... Also, a while ago the output of "set language" was made out of order as side effect of some other change. While I was at it, I made them sorted again. gdb/ChangeLog: 2017-07-20 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_language_defn): Make extern. (_initialize_ada_language): Remove add_language call. * c-lang.c (c_language_defn, cplus_language_defn) (asm_language_defn, minimal_language_defn): Make extern. (_initialize_c_language): Delete. * completer.c (compare_cstrings): Delete, moved to utils.h. * d-lang.c (d_language_defn): Make extern. (_initialize_d_language): Remove add_language calls. * defs.h (enum language): Add comment. * f-lang.c (f_language_defn): Make extern. (_initialize_f_language): Remove add_language call. * go-lang.c (go_language_defn): Make extern. (_initialize_go_language): Remove add_language call. * language.c: Include <algorithm>.

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.
