currently "b func tion" manages to set a breakpoint at "function" ! All these years I had never noticed this, but now that the linespec completer actually works, this easily happens by accident, with: "b func t<tab>" expecting to get "thread", but getting instead: "b func tion" ... Also, this: "b rettypefunc<int>" manages to set a breakpoint on "rettype func<int>()". These things happen due to strcmp_iw "magic". Fix it by teaching strcmp_iw about when can it skip whitespace. This required handling user-defined operators, and scope operators, complicating the code a bit, unfortunately. I added unit tests for all the corner cases I stumbled on, as I was developing this, and then in the end wrote a testsuite testcase covering many of the same things and more (to be added later). gdb/ChangeLog: 2017-11-24 Pedro Alves <palves@redhat.com> * cp-support.c (cp_symbol_name_matches_1): New, factored out from cp_fq_symbol_name_matches. Pass language_cplus to strncmp_with_mode. (cp_fq_symbol_name_matches): Call cp_symbol_name_matches_1. (selftests::test_cp_symbol_name_cmp): New. (_initialize_cp_support): Register "cp_symbol_name_matches" selftests. * language.c (default_symbol_name_matcher): Pass language_minimal to strncmp_iw_with_mode. * utils.c: Include "cp-support.h" and <algorithm>. (valid_identifier_name_char, cp_skip_operator_token, skip_ws) (cp_is_operator): New functions. (strncmp_iw_with_mode): Use them. Add language parameter. Don't skip whitespace in the symbol name when the lookup name doesn't have spaces, and vice versa. (strncmp_iw, strcmp_iw): Pass language to strncmp_iw_with_mode. * utils.h (strncmp_iw_with_mode): Add language 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.
