[PATCH 2/3] Allow divmod on UNITS_PER_WORD vectors

[Richard Henderson]

IA64 vectors modes are of course all UNITS_PER_WORD.  I see no reason
to prevent the transformation of a V4HImode divmod, or even of V2SImode.

Jakub, was there another reason you added this condition?

        * tree-vect-patterns.c (vect_recog_divmod_pattern): Do not require
        vectors larger than UNITS_PER_WORD.
