            Bug ID: 112577
           Summary: aarch64_class_max_nregs mishandles 64-bit structure
                    modes
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

As noted in https://gcc.gnu.org/pipermail/gcc-patches/2023-November/636874.=
html
, aarch64_class_max_nregs returns the wrong value for 64-bit structure modes
like V3x1DI.  Should be simple to fix.=
