From 2b77eef1609d907c0d617f375087b27af9abd152 Mon Sep 17 00:00:00 2001 From: Eli Friedman Date: Thu, 9 Jul 2009 22:01:03 +0000 Subject: Make EXTRACT_VECTOR_ELT a bit more flexible in terms of the returned value. Adjust other code to deal with that correctly. Make DAGTypeLegalizer::PromoteIntRes_EXTRACT_VECTOR_ELT take advantage of this new flexibility to simplify the code and make it deal with unusual vectors (like <4 x i1>) correctly.
