The justification of this change is here: http://lists.cs.uiuc.edu/pipermail/llvmdev/2015-March/082989.html According to the current GEP syntax, vector GEP requires that each index must be a vector with the same number of elements. %A = getelementptr i8, <4 x i8*> %ptrs, <4 x i64> %offsets In this implementation I let each index be or vector or scalar. All vector indices must have the same number of elements. The scalar value will mean the splat vector value. (1) %A = getelementptr i8, i8* %ptr, <4 x i64> %offsets or (2) %A = getelementptr i8, <4 x i8*> %ptrs, i64 %offset In all cases the %A type is <4 x i8*> In the case (2) we add the same offset to all pointers. The case (1) covers C[B[i]] case, when we have the same base C and different offsets B[i]. The documentation is updated. http://reviews.llvm.org/D10496 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@241788 91177308-0d34-0410-b5e6-96231b3b80d8
