Yes.

For x86-64, with Implies-after, the search order can only be

ieee754/ldbl-96
ieee754/dbl-64/wordsize-64
ieee754/dbl-64
ieee754/flt-32
wordsize-64

not

wordsize-64
ieee754/ldbl-96
ieee754/dbl-64/wordsize-64
ieee754/dbl-64
ieee754/flt-32

For x86-64, those 2 different orders don't make a difference.

BTW, the current search order for x86-64 is

wordsize-64
ieee754/ldbl-96
ieee754/dbl-64/wordsize-64
ieee754/dbl-64
ieee754/flt-32

Thanks.
