This is a minor extension of SROA to handle a special case that is important for some ARM NEON operations. Some of the NEON intrinsics return multiple values, which are handled as struct types containing multiple elements of the same vector type. The corresponding return types declared in the arm_neon.h header have equivalent arrays. We need SROA to recognize that it can split up those arrays and structs into separate vectors, even though they are not always accessed with the same type. SROA already handles loads and stores of an entire alloca by using insertvalue/extractvalue to access the individual pieces, and that code works the same regardless of whether the type is a struct or an array. So, all that needs to be done is to check for compatible arrays and homogeneous structs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123381 91177308-0d34-0410-b5e6-96231b3b80d8 |
