             Bug #: 14360
           Summary: parser: document string literal concatenation, drop /*
                    */ special treatment
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
        AssignedTo: systemtap@sourceware.org
        ReportedBy: fche@redhat.com
    Classification: Unclassified


Bug #11617 and its predecessor bug #11208 tweaked the way consecutive string
literals are glued together early during parsing.  The current behavior is not
properly documented in the man page, and has a special surprise, the
ate_comment flag that prevents gluing with an intermediary /* */.  This special
behavior should be dropped unless well-motivated and documented.  This should
result in simpler parser code.  (If we decide to preserve current behavior with
--compatible=1.8, the code simplification benefits won't accrue. :-(
