Re: [Linaro-TCWG-CI] gcc-16-1550-g9244ea4bf556: Failure on aarch64

Could you file a glibc bug for this please? It needs some analysis to
see if it's an FP or not.

There's actually a suppression for -Os already there:

                            if (elem < table_size)
                              {
                                /* Compare the byte sequence but only if
                                   this is not part of a range.  */

                                /* The compiler might warn that idx may be
                                   used uninitialized, however it will be
                                   reached iff elem < table_size which means
                                   that it was properly set in the loop
                                   above.   */
                                DIAG_PUSH_NEEDS_COMMENT;
                                DIAG_IGNORE_Os_NEEDS_COMMENT (8, "-Wmaybe-uninitialized");
                                if (! is_range

# if WIDE_CHAR_VERSION
                                    && __wmemcmp (n, &wextra[1], c1) == 0
# else
                                    && memcmp (n, &extra[idx + 1], c1) == 0
# endif
                                    )
                                  {
                                    n += c1 - 1;
                                    goto matched;
                                  }
                                DIAG_POP_NEEDS_COMMENT;
