new sandbox test (Kyle Evans @ FreeBSD)

branches: 1.8.4;
Temporary hack to work around incorrect/missing unwind info for
the t_sig_backtrace test case on ARM when compiled with optimization.

Add a test case for backtrace(3) across a signal handler.

The test requires symbols, so put STRIPFLAG= explicitly to avoid
stripping them if STRIPFLAG?=-s is defined in /etc/mk.conf.

Merge riastradh-drm2 to HEAD.

Fix build with stack-protection enabled.

branches: 1.3.2;
Use conditional calls to vfork() to prevent the compiler from inlining
the intermediate stack frames. Mark the __start frame as optional.

branches: 1.2.2; 1.2.4;
Fix destination directory

add a test for the backtrace function.

PR/55648: Kyle Evans: Minor warnings in compilation of libexecinfo test2

PR misc/49356 remove unnecessary references to atf-c/config.h

The function included via this header is not used and is removed in
later versions of atf, so let us avoid it.

Check for mounted /proc.

Bail out if backtrace(3) failed.

branches: 1.13.2;
Use a struct for pair of frame name and whether it is optional. Add some
additional entries found in a -O0 build of ATF on PowerPC.

New gcc can reuse stack frames for tail calls, so "main" is an optional
frame as well.

Make the output of the test case better suited for debugging (output full
backtrace before failing any unclear asserts)

Prevent inlining of the main testcase body function.
Do not mark the inner functions static, as they might get cloned then
(ending up being called "myfunc3.clone.3" instead of "myfunc").

Now that all architectures default to unwind data, remove the failure
for !amd64.

Put the vfork at the end.

Use conditional calls to vfork() to prevent the compiler from inlining
the intermediate stack frames. Mark the __start frame as optional.

Make back trace more robust. At least on i386, one of the intermediate
functions in ATF is not replaced by tail recursion elimination, so
mark it as optional.

branches: 1.5.2; 1.5.4;
Adjust test for recent atf_machine (amd64) -> atf_arch (x86_64)
change.

Use "atf_arch" instead of "atf_machine"; see atf-config(1).

Skip test on non-amd64 machines for now, pointing to PR 46490.

Not a good idea to continue testing if basic assertions fail - only will
cause core dumps later.

add a test for the backtrace function.

branches: 1.3.4;
fork and don't use atf in the child (from martin@)

t_backtrace_sandbox: Nix trailing whitespace.

No functional change intended.

t_sig_backtrace: Mark xfail on sparc.

Also change ATF_REQUIRE to ATF_CHECK to get more diagnostics out in a
single test run, where appropriate.

PR port-sparc64/59313: t_sig_backtrace tests are failing

branches: 1.7.2;
t_sig_backtrace: Flush stdout before writing to STDOUT_FILENO.

Avoids confusing ordering of output.

t_sig_backtrace: Pacify vfork clobber warning with volatile.

execinfo(3): Mark sig_backtrace_jump test as xfail.

PR lib/56940

execinfo: Fix mistake in previous: match `the_loop*' as prefix.

Now that there are two functions we need to catch either one.

execinfo: Test stack traces through null pointer jump too.

the t_sig_backtrace test case on ARM when compiled with optimization.
