            Bug ID: 16726
           Summary: RFE: provide a way to retrieve tapset function types
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: tapsets
          Assignee: systemtap at sourceware dot org
          Reporter: aferrazz at redhat dot com

Running 'stap -vp1' (verbose pass 1, with any provided script) outputs a dump
of all tapset contents; however, tapset functions and their parameters are
printed without their types.

It is possible to infer function & parameter types with pass 2, but that only
examines the functions which are called by a provided script.

I acknowledge that inferring the types of all functions & parameters of all
included tapsets may be processor-intensive, but it may be a useful optional
feature to have available.

For instance, SystemTap IDE for Eclipse (which I contribute to) features a
visual list of all tapset functions & their parameters, with icons next to each
entry to signify return & parameter types. At the moment, the only way to
obtain the types is to directly examine each function's definition in its host
tapset file (if it provides type information at all). In a case such as this,
being able to dump all tapset contents with types inferred would be useful.
