From 4b66b47a7ccde60c32f8004dd7e68239f9d67e1f Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Mon, 27 Jul 2009 21:46:02 +0000 Subject: [PATCH] Make raw_null_ostream flush its buffer in its destructor, so that it conforms to the assertion added in r77245. This fixes a failure in qa_override.c in clang's testsuite. llvm-svn: 77255 --- llvm/include/llvm/Support/raw_ostream.h | 1 + llvm/lib/Support/raw_ostream.cpp | 9 +++++++++ 2 files changed, 10 insertions(+) diff --git a/llvm/include/llvm/Support/raw_ostream.h b/llvm/include/llvm/Support/raw_ostream.h index 3527984..246fdb9 100644 --- a/llvm/include/llvm/Support/raw_ostream.h +++ b/llvm/include/llvm/Support/raw_ostream.h @@ -420,6 +420,7 @@ class raw_null_ostream : public raw_ostream { public: explicit raw_null_ostream() {} + ~raw_null_ostream(); }; } // end llvm namespace diff --git a/llvm/lib/Support/raw_ostream.cpp b/llvm/lib/Support/raw_ostream.cpp index 7e34e06..992c11a 100644 --- a/llvm/lib/Support/raw_ostream.cpp +++ b/llvm/lib/Support/raw_ostream.cpp @@ -438,6 +438,15 @@ uint64_t raw_svector_ostream::tell() { // raw_null_ostream //===----------------------------------------------------------------------===// +raw_null_ostream::~raw_null_ostream() { +#ifndef NDEBUG + // ~raw_ostream asserts that the buffer is empty.
