             Bug #: 14832
           Summary: Add file/line/func context variables
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: translator
        AssignedTo: systemtap@sourceware.org
        ReportedBy: jistone@redhat.com
    Classification: Unclassified


For all the DWARF probe types, we could expose more context information as
virtual variables.  Perhaps $$file, $$line, $$func, and $$pretty_function,
equivalent to __FILE__, __LINE, __func__, and __PRETTY_FUNCTION__.

One motivating point for $$func -- since probefunc() was converted to use the
current PC and symnames, it doesn't work well for inline or return probes.  For
example, para-callgraph.stp is printing the wrong name in the return lines,
showing actually where we returned TO, not which function is returning.

See also bug #12276, which could apply to non-dwarf generic contexts.
