There's a good idea in bug #5899 comment #4 to support saving arbitrary expressions as well. I quite like the example: probe FOO.return { println(gettimeofday_ns() - @entry(gettimeofday_ns())) } This @entry syntax is somewhat distinct from #5899, so I thought it should be its own bug. I think our traditional saved_var[tid()] mechanism could be adapted for this pretty easily. The newer method using the kretprobe data pouch (bug #5916) is a little tricker though, as it would need the types to be resolved a bit earlier than we do now. -- Summary: Support generic @entry saving in .return probes Product: systemtap Version: unspecified Status: NEW Severity: normal Priority: P2 Component: translator AssignedTo: systemtap at sources dot redhat dot com ReportedBy: jistone at redhat dot com http://sourceware.org/bugzilla/show_bug.cgi?id=10943 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ^ permalink raw reply [flat|nested] 5+ messages in thread
