From 0f554492467064b3198df509227a3e902cf7cf1f Mon Sep 17 00:00:00 2001 From: Benjamin Kramer Date: Sun, 8 Apr 2012 14:53:14 +0000 Subject: [PATCH] EngineBuilder::create is expected to take ownership of the TargetMachine passed to it. Delete it on error or when we create an interpreter that doesn't need it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154288 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/ExecutionEngine/ExecutionEngine.cpp | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/lib/ExecutionEngine/ExecutionEngine.cpp b/lib/ExecutionEngine/ExecutionEngine.cpp index 9f7b20f20bc..a744d0c1e79 100644 --- a/lib/ExecutionEngine/ExecutionEngine.cpp +++ b/lib/ExecutionEngine/ExecutionEngine.cpp @@ -448,6 +448,8 @@ ExecutionEngine *ExecutionEngine::createJIT(Module *M, } ExecutionEngine *EngineBuilder::create(TargetMachine *TM) { + OwningPtr TheTM(TM); // Take ownership. + // Make sure we can resolve symbols in the program as well.
