--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The aarch64_cmpeqdf instruction no longer matches, because the CONST0_RTX (DFmode) operand doesn't match the aarch64_simd_reg_or_zero predicate. Either aarch64_simd_reg_or_zero predicate should use aarch64_simd_or_scalar_imm_zero rather than aarch64_simd_imm_zero, or the aarch64_cmp<optab><mode> pattern with VHSDF_HSDF needs to use some other predicate at least for the scalar modes.
