Subject: [PATCH] Add widenin
Hi,
for integral modes, the expansion of MULT_HIGHPART_EXPR requires the presence
of an {s,u}mul_highpart optab whereas, for vector modes, widening expansion is
supported. This adds a widening expansion for integral modes too, which is in
fact already implemented in expmed_mult_highpart_optab.
