    the aarch64_sve_prepare_conditional_op call.
    (cond_<SVE_INT_BINARY_SD><SVE_SDI>): Likewise.
    (cond_<SVE_COND_FP_BINARY><SVE_F>): Likewise.
    (*cond_<SVE_INT_BINARY><SVE_I>_z): New pattern.
    (*cond_<SVE_INT_BINARY_SD><SVE_SDI>_z): New pattern.
    (*cond_<SVE_COND_FP_BINARY><SVE_F>_z): New pattern.
    (*cond_<SVE_INT_BINARY><SVE_I>_any): New pattern.
    (*cond_<SVE_INT_BINARY_SD><SVE_SDI>_any): New pattern.
    (*cond_<SVE_COND_FP_BINARY><SVE_F>_any): New pattern
    and a splitters to match all of the *_any patterns.
    * config/aarch64/predicates.md (aarch64_sve_any_binary_operator): New.

    * config/aarch64/iterators.md (SVE_INT_BINARY_REV): Remove.
    (SVE_COND_FP_BINARY_REV): Remove.
    (sve_int_op_rev, sve_fp_op_rev): New.
    * config/aarch64/aarch64-sve.md (*cond_<SVE_INT_BINARY><SVE_I>_0): New.
    (*cond_<SVE_INT_BINARY_SD><SVE_SDI>_0): New.
    (*cond_<SVE_COND_FP_BINARY><SVE_F>_0): New.
    (*cond_<SVE_INT_BINARY><SVE_I>_2): Rename, add movprfx alternative.
    (*cond_<SVE_INT_BINARY_SD><SVE_SDI>_2): Similarly.
    (*cond_<SVE_COND_FP_BINARY><SVE_F>_2): Similarly.
    (*cond_<SVE_INT_BINARY><SVE_I>_3): Similarly; use sve_int_op_rev.
    (*cond_<SVE_INT_BINARY_SD><SVE_SDI>_3): Similarly.
    (*cond_<SVE_COND_FP_BINARY><SVE_F>_3): Similarly; use sve_fp_op_rev.

    * config/aarch64/aarch64-sve.md (cond_<SVE_COND_FP_BINARY><SVE_F>):
    Remove match_dup 1 from the inner unspec.
    (*cond_<SVE_COND_FP_BINARY><SVE_F>): Likewise.

    * config/aarch64/aarch64.md (movprfx): New attr.
    (length): Default movprfx to 8.
