But IMO it is a functionality regression as: * gdb_test_sequence permits arbitary number of lines of text between those lines being matched. Former regex string did not allow it. This may make a difference if GDB regresses by printing some unexpected line after the breakpoint info line (like a "silent" line). > * \[\r\n\]+ can be used to anchor the beginning of the pattern, in the sense > of Perl regex ^ /m match. At least I have found such cases in existing > *.exp files so I used that. Using ^ really does not work. > > But I am not aware how to do Perl regex $ /m match. Using $ really does > not work. But this means that for example the trailing > ( \\((host|target) evals\\))? > on the line > "\[\r\n\]+\[ \t\]+stop only if i == 1( \\((host|target) evals\\))?" > originally made sense there but now it can be removed as it has no longer > any functionality there - it will match now any trailing line garbage. by Yao Qi: In this test case, ( \\((host|target) evals\\))? isn't needed in the pattern. What we test here is to save breakpoints into file and restore them from file. The contents saved in file are: break save-bp.c:31 condition $bpnum i == 1 the information about the place where the condition is evaluated isn't saved, so we don't need to check. Breakpoint save and restore has nothing to do with where the condition is evaluated (host or target). I am fine to leave it here now. gdb/testsuite/ChangeLog 2014-10-09 Jan Kratochvil <jan.kratochvil@redhat.com> * gdb.base/save-bp.exp (info break): Use gdb_test_sequence.
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.
