            Bug ID: 97583
           Summary: Unknown mode_attribute (or iterator) ignored
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: rtl-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: segher at gcc dot gnu.org
  Target Milestone: ---

This leads to errors at compiler runtime instead of at compiler build time.
See https://gcc.gnu.org/pipermail/gcc-patches/2020-October/556998.html .

Code from md_reader::apply_iterator_to_string :

      p = start + 1;

      *end = 0;
      v = map_attr_string (loc, p);
      *end = '>';
      if (v == 0)
        continue;

It could report an error instead.
