Willy Tarreau c54ba41781 selftests/nolibc: Add a "run-user" target to test the program in user land ... When developing tests, it is much faster to use the QEMU Linux emulator instead of the system emulator, which among other things avoids kernel-build latencies. Although use of the QEMU Linux emulator does have its limitations (please see below), it is sufficient to test startup code, stdlib code, and syscall calling conventions. However, the current mainline Linux-kernel nolibc setup does not support this. Therefore, add a "run-user" target that immediately executes the prebuilt executable. Again, this approach does have its limitations. For example, the executable runs with the user's privilege level, which can cause some false-positive failures due to insufficient permissions. In addition, if the underlying kernel is old enough to lack some features that nolibc relies on, the result will be false-positive failures in the corresponding tests. However, for nolibc changes not affected by these limittions, the result is a much faster code-compile-test-debug cycle. With this patch, running a userland test is as simple as issuing: make ARCH=xxx CROSS_COMPILE=xxx run-user Signed-off-by: Willy Tarreau <w@1wt.eu> Tested-by: Ammar Faizi <ammarfaizi2@gnuweeb.org> Signed-off-by: Paul E.
