            Bug ID: 79873
           Summary: function_reader::handle_insn_uids: use internal_error
                    instead of error
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: rtl-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: roland.illig at gmx dot de
  Target Milestone: ---

from read-rtl-function.c:

error ("duplicate insn UID: %i", INSN_UID (insn));

As an i18n translator, I'm not willing to translate this into a human-readable
error message, since it looks like an internal compiler error. As such, there
is no benefit of having this error message in 100 different languages.
