Changes in directory llvm/lib/Support:
Debug.cpp updated: 1.7 -> 1.8
---
Log message:
Added "DOUT" macro. This is used as a replacement for the std::cerr
stream. It centralizes the use of std::cerr so that static c'tor/d'tors
aren't scattered around all over the place. The way to use it is like this:
DOUT << "This is a status line: " << Var << "\n";
If "-debug" is specified, it will print. Otherwise, it'll not print. If
NDEBUG is defined, the DOUT does nothing.
