From 9d7c776d32c8a4d64b37a91c2d627629cf1498ef Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Tue, 19 Nov 2013 06:35:35 +0000 Subject: Merging r195092: ------------------------------------------------------------------------ r195092 | ributzka | 2013-11-18 19:08:35 -0800 (Mon, 18 Nov 2013) | 5 lines [weak vtables] Place class definitions into anonymous namespaces to prevent weak vtables. This patch places class definitions in implementation files into anonymous namespaces to prevent weak vtables. This eliminates the need of providing an out-of-line definition to pin the vtable explicitly to the file. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@195111 91177308-0d34-0410-b5e6-96231b3b80d8 --- examples/Kaleidoscope/Chapter3/toy.cpp | 8 +++----- 1 file changed, 3 insertions(+), 5 deletions(-) (limited to 'examples/Kaleidoscope/Chapter3') diff --git a/examples/Kaleidoscope/Chapter3/toy.cpp b/examples/Kaleidoscope/Chapter3/toy.cpp index 2494345..a7b60ba 100644 --- a/examples/Kaleidoscope/Chapter3/toy.cpp +++ b/examples/Kaleidoscope/Chapter3/toy.cpp @@ -80,17 +80,14 @@ static int gettok() { //===----------------------------------------------------------------------===// // Abstract Syntax Tree (aka Parse Tree) //===----------------------------------------------------------------------===// - +namespace { /// ExprAST - Base class for all expression nodes. class ExprAST { public: - virtual ~ExprAST(); + virtual ~ExprAST() {} virtual Value *Codegen() = 0; }; -// Provide out-of-line definition to prevent weak vtable. -ExprAST::~ExprAST() {} - /// NumberExprAST - Expression class for numeric literals like "1.0". class NumberExprAST : public ExprAST { double Val; @@ -150,6 +147,7 @@ public: Function *Codegen(); }; +} // end anonymous namespace //===----------------------------------------------------------------------===// // Parser -- cgit v1.1
