Subject: [PATCHSET 00/12] perf test: Add test workloads (v3)

Hello,

In the shell tests, it needs to run a custom test workload to verify
the behaviors.  This requires a working compiler when it runs the
tests.  However it's not available in some test environments, making
hard to run those tests.

changes in v3)
 * update brstack to set num_loops  (James)
 * fix a typo in the brstack test  (German)
 * add tags rom German and James

changes in v2)
 * use sig_atomic_t  (Arnaldo)
 * fix callgraph fp test  (Leo)
 * fix bulid in sqrtloop  (German)
 * add tags from Leo Yan

So I've added the test workload to the perf binary directly, so that
we can run them simply like:

  $ perf test -w noploop

And convert most of the shell tests need compilers with this workloads.
The buildid test still requires a compiler since it needs to check
different build options to generate different kind of build-IDs.

I've checked perf test result after the changes but could not verify
architecture-specific ones (e.g. for arm64).  It'd be nice if anyone
can check it out.

You can find it in 'perf/test-workload-v3' branch in

  git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Thanks,
Namhyung
