Compiling testsuite/gcc.dg/pr104612.c on s390x results in:

# gcc -c pr104612.c -O2
pr104612.c: In function ‘foo’:
pr104612.c:15:1: error: unrecognizable insn:
   15 | }
      | ^

        (ior:V2SF (and:V2SF (subreg:V2SF (reg/v:DI 63 [ v ]) 0)
                (reg:V2SF 65))

This works with GCC 11.
