* [PATCH, PR tree-optimization/68327] Compute vectype for live phi nodes when copmputing VF @ 2015-11-18 11:34 Ilya Enkovich 2015-11-18 13:44 ` Richard Biener 0 siblings, 1 reply; 7+ messages in thread From: Ilya Enkovich @ 2015-11-18 11:34 UTC (permalink / raw) To: gcc-patches Hi, When we compute vectypes we skip non-relevant phi nodes. But we process non-relevant alive statements and thus may need vectype of non-relevant live phi node to compute mask vectype. This patch enables vectype computation for live phi nodes.
