[llvm-commits] [llvm] r55114 - /llvm/trunk/include/llvm/Support/raw_ostream.h

New Revision: 55114

URL: http://llvm.org/viewvc/llvm-project?rev=55114&view=rev
Log:
Implement operator<< in terms of basic types rather than [u]int*_t, which is better for portability.  There might be some way to factor this all with metaprogramming magic, but I'm not sure how offhand.
