We supported transforming: (gep i8* X, -(ptrtoint Y)) to: (inttoptr (sub (ptrtoint X), (ptrtoint Y))) However, this only fired if 'X' had type i8*. Generalize this to support various types of different sizes. This results in much better CodeGen, especially for pointers to packed structs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216523 91177308-0d34-0410-b5e6-96231b3b80d8
