Subject: [PATCH] tests: add strace-k-p test
Add a check of the stack unwinding for attached processes.
* tests/stack-fcall-attach.c: New file.
* tests/strace-k-p.expected: Likewise.
* tests/strace-k-p.test: New test.
* tests/Makefile.am (EXTRA_DIST): Add strace-k-p.expected and strace-k-p.test.
(STACKTRACE_TESTS): Add strace-k-p.test
(check_PROGRAMS): Add stack-fcall-attach.
(stack_fcall_attach_SOURCES): New variable.
* tests/stack-fcall.c: Include "tests.h" and <unistd.h>.
[!ATTACH_MODE] (ATTACH_MODE): Define to 0.
(main) [ATTACH_MODE]: Wait a bit.
* tests/strace-k.test: Add attach mode.
Complements: v5.4-18-g69b2c33 "unwind-libdw: fix initialization of libdwfl cache"
---
Backport changes:
* "SIGURG" line has been removed from tests/strace-k-p.expected, as it requires
v4.25~22 "Print stack traces on signals" and v4.25~21 "tests: check stack
unwinding for signals".
* "chdir" usage in tests/strace-k-p.expected has been replaced with "getpid",
as it is the syscall that was used in the stack-fcall.c at the time.
* Added the respective changes to tests/Makefile.in file.
* The changes to tests/stack-fcall-attach.c, tests/strace-k-p.expected,
tests/strace-k-p.test, tests/Makefile.am, tests/stack-fcall.c,
and tests/strace-k.test have been copied over to tests-m32 and tests-mx32
directories.
