From 4a717d4a478ec40eb3b42078843af2291203ea21 Mon Sep 17 00:00:00 2001 From: "Vikram S. Adve" Date: Sun, 14 Jul 2002 22:46:32 +0000 Subject: [PATCH] Add a couple of virtual functions to support subclass ConstantExpr. Note that a ConstantExpr can be of any type, so classof() in most other subclasses (that discriminate by type) have to check that it is also not a ConstantExpr. This is why isConstantExpr() is needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2890 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Constant.h | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/include/llvm/Constant.h b/include/llvm/Constant.h index 572d1d15ca9..36a26d7f25c 100644 --- a/include/llvm/Constant.h +++ b/include/llvm/Constant.h @@ -37,11 +37,20 @@ public: virtual void print(std::ostream &O) const; + // isConstantExpr - Return true if this is a ConstantExpr + virtual bool isConstantExpr() const { return false; } + // Methods for support type inquiry through isa, cast, and dyn_cast: static inline bool classof(const Constant *) { return true; } static inline bool classof(const Value *V) { return V->getValueType() == Value::ConstantVal; } + + // WARNING: Only to be used by Bytecode & Assembly Parsers!
