            Bug ID: 104085
           Summary: mips: libstdc++ ABI check compares against wrong file
                    if GCC is configured with --with-abi=(32|64)
           Product: gcc
           Version: 11.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: xry111 at mengyan1223 dot wang
  Target Milestone: ---

If GCC is configured with --with-abi={anything other than n32}, the directory
layout produced by -print-multi-directory will be different with the layout of
libstdc++-v3/config/abi/post/mips64-linux-gnu, causing ABI check failure.
