Bob Wilson a1fe2948ed Fix SROA to avoid unnecessary scalar conversions for 1-element vectors. ... When a 1-element vector alloca is promoted, a store instruction can often be rewritten without converting the value to a scalar and using an insertelement instruction to stuff it into the new alloca. This patch just adds a check to skip that conversion when it is unnecessary. This turns out to be really important for some ARM Neon operations where <1 x i64> is used to get around the fact that i64 is not a legal type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184870 91177308-0d34-0410-b5e6-96231b3b80d8		2013-06-25 19:09:50 +00:00
