2009-05-09When evaluating pointer arithmetic, if the base location is a symbolic region,Zhongxing Xu
convert it to the first element region. Also do not assume the array region is typed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71358 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-09Do not create a TypedViewRegion when the base struct region is a symbolicZhongxing Xu
region. In the future we may set the cast-to type as the same time. But for now, we simply leave it as it is. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71357 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-09Do not layer a TypedViewRegion when casting symbolic or alloca regions.Zhongxing Xu
Modify getLValueElement accordingly. Now we don't require base region to be a typed region. Do not create TypedViewRegion when base region is symbolic or alloca region. We can do so because each element region has its type information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71355 91177308-0d34-0410-b5e6-96231b3b80d8
