We have several places doing essentially the same thing; factor them out to a central place. Some of the places overallocate for no good reason, or use strcat unnecessarily. The centralized version is more precise and to the point. (I considered making the gdb::unique_xmalloc_ptr overload version of make_completer_match_str try to realloc (not xrealloc) probably avoiding an allocation in most cases, but that'd be probably overdoing it, and also, now that I'm writing this I thought I'd try to see how could we ever get to filename_completer with "text != word", but I couldn't figure it out. Running the testsuite with 'gdb_assert (text == word);' never tripped on the assertion either. So post gdb 8.1, I'll probably propose a patch to simplify filename_completer a bit, and the gdb::unique_xmalloc_str overload can be removed then.) gdb/ChangeLog: 2017-12-13 Pedro Alves <palves@redhat.com> * cli/cli-decode.c (complete_on_cmdlist, complete_on_enum): Use make_completion_match_str. * completer.c: Use gdb::unique_xmalloc_ptr and make_completion_match_str. (make_completion_match_str_1): New. (make_completion_match_str(const char *, const char *, const char *)): New. (make_completion_match_str(gdb::unique_xmalloc_ptr<char> &&, const char *, const char *)): New. * completer.h (make_completion_match_str(const char *, const char *, const char *)): New. (make_completion_match_str(gdb::unique_xmalloc_ptr<char> &&, const char *, const char *)): New. * interps.c (interpreter_completer): Use make_completion_match_str. * symtab.c (completion_list_add_name, add_filename_to_list): Use make_completion_match_str.
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.
