From b757f160fc86b7668e7d0ffcadccde36c4dcfec8 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Wed, 14 Jul 2004 18:13:54 +0000 Subject: * Change code to use a static_cast instead of reinterpret_cast * Add comments * Add two new gep ctors for the very common case of creating a two operand GEP instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14820 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/iMemory.h | 19 +++++++++++++++++-- 1 file changed, 17 insertions(+), 2 deletions(-) (limited to 'include') diff --git a/include/llvm/iMemory.h b/include/llvm/iMemory.h index 5421582..dcc647f 100644 --- a/include/llvm/iMemory.h +++ b/include/llvm/iMemory.h @@ -273,18 +273,31 @@ public: /// class GetElementPtrInst : public Instruction { GetElementPtrInst(const GetElementPtrInst &EPI) - : Instruction(reinterpret_cast(EPI.getType()), GetElementPtr) { + : Instruction((static_cast(&EPI)->getType()), + GetElementPtr) { Operands.reserve(EPI.Operands.size()); for (unsigned i = 0, E = EPI.Operands.size(); i != E; ++i) Operands.push_back(Use(EPI.Operands[i], this)); } void init(Value *Ptr, const std::vector &Idx); - + void init(Value *Ptr, Value *Idx0, Value *Idx1); public: + /// Constructors - Create a getelementptr instruction with a base pointer an + /// list of indices.
