Bug #: 14709
Summary: Support process.function.return in stapdyn
Product: systemtap
Version: unspecified
Status: NEW
Severity: enhancement
Priority: P2
Component: dyninst
AssignedTo: systemtap@sourceware.org
ReportedBy: jistone@redhat.com
Classification: Unclassified
We should support process.function.return in stapdyn. There's no such thing as
uretprobes here, of course, but BPatch_addressSpace::wrapFunction might do the
trick. That might even be a better way to handle function entry probes too.

Commit 536f1261 adds return probes using the containing function's
BPatch_locExit.
RE the notion to mess with entry probes -- better not, actually, since a lot of
dwarf expressions depend on knowing where exactly we are instrumented.
