Cameron Zwarich 85b0f468cf Only convert allocas to scalars if it is profitable. The profitability metric I ... chose is having a non-memcpy/memset use and being larger than any native integer type. Originally I chose having an access of a size smaller than the total size of the alloca, but this caused some minor issues on the spirit benchmark where SRoA runs again after some inlining. This fixes <rdar://problem/8613163>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127718 91177308-0d34-0410-b5e6-96231b3b80d8		2011-03-16 00:13:44 +00:00
