[llvm-commits] [PATCH] [Support][Endian] Add support for specifying the alignment and native unaligned types.

[Michael Spencer]

  * Simplified AlignedCharArrayUnion

  I attempted to fix the UB in read and write, however, this doesn't work in clang :(. I think it would only work if the typedef isn't accessed via indirection. alignof(aligned_ulittle32_t) is correct, but it doesn't generate more aligned loads than 1.
