From 1ea783f13a83ce9402f543fbc2367d125dc26f91 Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Fri, 17 Nov 2006 00:49:12 +0000 Subject: 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31798 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Support/Debug.cpp | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'lib/Support/Debug.cpp') diff --git a/lib/Support/Debug.cpp b/lib/Support/Debug.cpp index 394d9c1109..cbf12c7c0d 100644 --- a/lib/Support/Debug.cpp +++ b/lib/Support/Debug.cpp @@ -25,6 +25,7 @@ #include "llvm/Support/Debug.h" #include "llvm/Support/CommandLine.h" +#include using namespace llvm; bool llvm::DebugFlag; // DebugFlag - Exported boolean set by the -debug option @@ -63,3 +64,14 @@ bool llvm::isCurrentDebugType(const char *DebugType) { return false; #endif } + +// getErrorOutputStream - Returns the error output stream (std::cerr).
