            Bug ID: 30115
           Summary: Investigate use of case-folding in cooked-index
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: symtab
          Assignee: unassigned at sourceware dot org
          Reporter: tromey at sourceware dot org
  Target Milestone: ---

Right now the cooked index does case-insensitive comparisons.
But is this really needed?

I think there are a few case-insensitive languages in gdb.

GNAT already case-folds all symbol names.  In fact, due to the
way GNAT encodes non-ASCII characters, case-folding in the index
might mean that you could construct a situation where symbol
lookup finds the wrong thing.

I haven't looked to see what Pascal, Modula-2, or Fortran do.

However, for those, one option might be to do the folding as
a canonicalization step.

--- Comment #1 from Tom Tromey <tromey at sourceware dot org> ---
Actually, this is needed to handle "set case-sensitive off".
It might also be needed so that Ada users can print C
globals without trying to get the case correct (though in
a brief test I couldn't get that working).
