forked from Imagelibrary/binutils-gdb
d8b79a1f24
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 be 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
