            Bug ID: 16570
           Summary: the syscall.exp and nd_syscall.exp testcases take too
                    long
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: testsuite
          Assignee: systemtap at sourceware dot org
          Reporter: dsmith at redhat dot com

I've been adding more C testcases for the syscall/nd_syscall testsuite. I've
noticed that these testcases take a long time to run. On a recent debug x86_64
kernel, the syscall testsuite took over 38 minutes to run.

From some debugging, the majority of that time is spent compiling and
recompiling the test module. Even using a cached module, it takes a lot of time
to process the sys.stp/nd_sys.stp scripts since they probe every syscall.

Compiling the module once, then using staprun to load the resulting module
should speed these tests up.

--- Comment #1 from David Smith <dsmith at redhat dot com> ---
Commit 661d7be causes the test script to be compiled once. With this change,
the syscall.exp testcase takes under 3 minutes.
