forked from Imagelibrary/binutils-gdb

Cygwin debugging does not support follow fork. There is currently no
interface between the debugger and the Cygwin runtime to be able to
intercept forks and execs. Consequently, testcases that try to
exercise fork/exec all FAIL, and several hit long cascading timeouts.
Add a new allow_fork_tests procedure, meant to be used with require,
and sprinkle it throughout testcases that exercise fork.
Note that some tests currently are skipped on targets other than
Linux, with something like:
# Until "set follow-fork-mode" and "catch vfork" are implemented on
# other targets...
#
if {![istarget "*-linux*"]} {
continue
}
However, some BSD ports also support fork debugging nowadays, and the
testcases were never adjusted... That is why the new allow_fork_tests
procedure doesn't look for linux.
With this patch, on Cygwin, I get this:
$ make check TESTS="*/*fork*.exp"
...
=== gdb Summary ===
# of expected passes 6
# of untested testcases 1
# of unsupported tests 31

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.
