When a second systemtap instrumentation probe is attempted the translator cannot find debuginformation for the stap_[0-9]+ module. So for example the tests/testsuite/systemtap.stress/current.stp script was built and left running (any systemtap instrumentation script would work). A second current.stp script was attempted and failed in the following way: $ stap -g systemtap.stress/current.stp semantic error: c$ stap -g systemtap.stress/current.stp semantic error: cannot find module stap_21942 debuginfo: No such file or directory semantic error: cannot find module stap_21942 debuginfo: No such file or directory Pass 2: analysis failed. Try again with more '-v' (verbose) options. annot find module stap_21942 debuginfo: No such file or directory semantic error: cannot find module stap_21942 debuginfo: No such file or directory Pass 2: analysis failed. Try again with more '-v' (verbose) options. This is also going to present a problem for any module that doesn't have debugging information, e.g. third party device drivers. Shouldn't this be a warning and just not instrument the module missing the debuginfo rather than failing? -- Summary: running multiple systemtap instrumentation when module("*") is used Product: systemtap Version: unspecified Status: NEW Severity: normal Priority: P2 Component: translator AssignedTo: systemtap at sources dot redhat dot com ReportedBy: wcohen at redhat dot com http://sourceware.org/bugzilla/show_bug.cgi?id=2422 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
