--- Comment #1 from Haochen Jiang <haochen.jiang at intel dot com> --- I further checked the reason, V2SI should never dropped into that function because we have no pattern under V2SI. I suppose it is because -march=cascadelake will open SSE4.1, with the new pattern, it wrongly dropped into that. -m32 will not ICE since TARGET_MMX_WITH_SSE need 64 bit and won't enable the new pattern.
