[PATCH] Avoid 1x vectors in tree-vect-generic (PR rtl-optimization/69896)

2016-02-26 Thread Jakub Jelinek
Hi! On ppc64, the widest (and only) supported vector mode for __int128 element type is V1TImode, and there is a V1TImode or opcode and a couple of others, but IMNSHO it is highly undesirable to lower BLKmode (say 2xTI, 4xTI etc.) generic vectors to V1TI instead of TI, there are no advantages in do
