commit c8bc20447d3c55a6d5b58b32275559fff5dbccfb
Author: Josh Stone <jistone@redhat.com>
Date:   Wed Jun 9 21:48:51 2010 -0400

    Give non-x86 a chance at uprobes SDT
    
    * tapsets.cxx (sdt_uprobe_var_expanding_visitor): No need to assert that
      we know dwarf_regs unless we actually encountered STAP_SDT_V2 with
      arg_count > 0.  V1 should continue to work on other architectures.

commit 6bff37abacf95b60a1d8d4c83c9e59e42ae1a7b9
Author: Josh Stone <jistone@redhat.com>
Date:   Wed Jun 9 21:44:42 2010 -0400

    Let probe_bench work on archs besides x86_64
    
    The cycles code is too x86_64-centric, but for now at least it's been
    neutered to let other archs report basic timing numbers.
    
    * scripts/probe_bench/bench.stp: Use get_cycles() instead of rdtsc().
    * scripts/probe_bench/bench.c (rdtsc): Return 0 unless on x86_64.  This
      needs more work and inline assembly to fit more architectures.

commit 18a4c1b66409e612192bc4188f3f91bbad97d79e
Author: Josh Stone <jistone@redhat.com>
Date:   Wed Jun 9 21:44:11 2010 -0400

    Ignore probe_bench's generated files

commit 71f083934a8aeb52a9cc331a00e39453cf412774
Author: Josh Stone <jistone@redhat.com>
Date:   Wed Jun 9 21:41:06 2010 -0400

    Short out errors in probe_bench
    
    * scripts/probe_bench/bench.sh (setup_test, stap_test): Report when an
      error occurred and return.

commit ca43a52c51367b1c2f582b31c3f3515495eb3b0a
Author: Josh Stone <jistone@redhat.com>
Date:   Wed Jun 9 21:38:56 2010 -0400

    Make sure the probe_bench can find sdt.h
    
    * scripts/probe_bench/bench.sh (setup_test): Give -I$STAP/include to gcc.
