Re: Testsuite run on ppc64

[William Cohen <wcohen@redhat.com>]

Hien, Thanks for running the the tests on PPC64. The systemtap.log won't 
give the details on the compilation failure, stap hides thoes details. 
Could you do the following?

For systemtap.base/kmodule.stp:

1) stap -V -k  ./systemtap.base/kmodule.stp compilation >& error.txt
2) post the error.txt and a tarball of the generated kernel module

For ./systemtap.samples/symbols.exp it looks like it only matched one 
line. Maybe modify the ./systemtap.samples/symbols.exp like the 
following to find out which line it is matching on. It looks like the 
regular expression needs to be corrected.

set test "symbols"

spawn stap -g ./$subdir/symbols.stp
set ok 0
expect {
     -timeout 30
     -re { 0x[a-f0-9]+.*\r} { incr ok; pass "$test matches"; exp_continue; }
     timeout { fail "$test (timeout)" }
     eof { }
}

It is odd that the results for the automated run of syscall1.stp and 
syscall2.stp differ from running by hand.
