[PATCH] D26196: Add support for non-zero null pointers

[Yaxun Liu via cfe-commits]

yaxunl retitled this revision from "[WIP] Add support for non-zero null pointers" to "Add support for non-zero null pointers".
yaxunl updated this revision to Diff 77210.
yaxunl added a comment.

Fixed list initialization of large struct which are mostly initialized by 0 through memset.
Added tests for casting literal 0 and non-literal integer to pointer.

There are many more places need to be changed. I am wondering if it makes sense to split this feature into multiple pieces, e.g. for C and OpenCL, C++, Objective-C, OpenMP, incrementally.
