From 0ac7e6f293bc502b39005496d2160b0089d3fa46 Mon Sep 17 00:00:00 2001 From: Richard Trieu Date: Thu, 24 Jan 2013 04:29:24 +0000 Subject: [PATCH] Add asserts to SmallVector so that calls to front() and back() only succeed if the vector is not empty. This will ensure that calls to these functions will reference elements in the vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173321 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/ADT/SmallVector.h | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/include/llvm/ADT/SmallVector.h b/include/llvm/ADT/SmallVector.h index 951e5741ffb..9167f872185 100644 --- a/include/llvm/ADT/SmallVector.h +++ b/include/llvm/ADT/SmallVector.h @@ -145,16 +145,20 @@ public: } reference front() { + assert(!empty()); return begin()[0]; } const_reference front() const { + assert(!empty()); return begin()[0]; } reference back() { + assert(!empty()); return end()[-1]; } const_reference back() const { + assert(!empty()); return end()[-1]; } }; -- 2.34.1
