[llvm-commits] [llvm] r43087 - /llvm/trunk/include/llvm/Support/Allocator.h

New Revision: 43087

URL: http://llvm.org/viewvc/llvm-project?rev=43087&view=rev
Log:
Added member template functions to MallocAllocator and
BumpPtrAllocator that implement allocations that return a properly
typed pointer.  For BumpPtrAllocator, the allocated memory is
automatically aligned to the minimum alignment of the type (as
calculated by llvm::AlignOf::Alignment).

Modified:
