            Bug ID: 107726
           Summary: Multiple bugs related to __gnu__::__target__
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: unlvsur at live dot com
  Target Milestone: ---

1. On Linux. the ld linker does not work. Only gold linker would work. (Sounds
like a linker bug) 
./sha512 a_file
./sha512: error while loading shared libraries: unexpected PLT reloc type 0x00


2. On x86_64-w64-mingw32 target.
../../include/fast_io_crypto/hash/sha512_simd16.h:68:13: error: multiversioning
needs 'ifunc' which is not supported on this target

And I tried clang with lld and yes it works even on windows.
