Chandler Carruth 07525a6be6 Teach SROA to cope with wrapper aggregates. These show up a lot in ABI type coercion code, especially when targetting ARM. Things like [1 x i32] instead of i32 are very common there. The goal of this logic is to ensure that when we are picking an alloca type, we look through such wrapper aggregates and across any zero-length aggregate elements to find the simplest type possible to form a type partition. This logic should (generally speaking) rarely fire. It only ends up kicking in when an alloca is accessed using two different types (for instance, i32 and float), and the underlying alloca type has wrapper aggregates around it. I noticed a significant amount of this occurring looking at stepanov_abstraction generated code for arm, and suspect it happens elsewhere as well. Note that this doesn't yet address truly heinous IR productions such as PR14059 is concerning. Those result in mismatched sizes of types in addition to mismatched access and alloca types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165870 91177308-0d34-0410-b5e6-96231b3b80d8		2012-10-13 10:49:33 +00:00
