+Subject: [PATCH] [OpenCL] Fix assertion due to blocks
+
+A recent change caused assertion in CodeGenFunction::EmitBlockCallExpr when a block is called.
+
+There is code
+
+  Func = CGM.getOpenCLRuntime().getInvokeFunction(E->getCallee());
+getCalleeDecl calls Expr::getReferencedDeclOfCallee, which does not handle
+BlockExpr and returns nullptr, which causes isa to assert.
+
+This patch fixes that.
