...ot;") Value * CreateConstGEP1_32 (Type *Ty, Value *Ptr, unsigned Idx0, const Twine &Name="") I'm assuming that this means that the caller can supply the expected type, and get error checking or casting? Or choose to not supply the type and get whatever they get? But for CreateConstGEP2_32, there is only the variety with the type supplied: Value * CreateConstGEP2_32 (Type *Ty, Value *Ptr, unsigned Idx0, unsigned Idx1, const Twine &Name="") For CreateConstGEP2_64, there is only the version with no Type supplied: Value * CreateConstGEP2_64 (Value *Ptr, uint64_t...

I notice that there's a lot of inconsistency in the various LLVM classes with respect to convenience methods. Here's some examples: For creating GEPS, IRBuilder has: CreateGEP (2 overloads) CreateInBoundsGEP (2 overloads) CreateConstGEP1_32 CreateConstInBoundsGEP1_32 CreateConstGEP2_32 CreateConstInBoundsGEP2_32 CreateConstGEP1_64 CreateConstInBoundsGEP1_64 CreateConstGEP2_64 CreateConstInBoundsGEP2_64 CreateStructGEP All of which are very useful. However, ConstExpression only has: getGetElementPtr getGetElementPtr getInBoundsGetElementPtr getInBoundsGetElem...

...e this: struct Foo { Thing *first; Blob *second; unsigned long third; }; Then I have a derived C++ class that look like this: struct Bar : Foo { long long fourth; } I generate JIT code to access 'fourth' from a Foo * as follows: BarPtr = CreateBitCast(FooPtr, BarPtrTy); FourthPtr = CreateConstGEP2_32(BarPtr, 0, 3); FourthValue = CreateLoad(FourthPtr); ConstantValue = ConstantInt::get(FourthValue->getType(), 0x2A4); ComparisonValue = CreateICmpEQ(FourthValue, ConstantValue); This appears to work on Linux and MacOSX with LLVM 2.6 and LLVM 2.7. On Windows, however, where I only have LLVM 2....

Emitting calls to these functions (written in an .ll file linked in) works fine, and does the right thing. %Any = type { i8*, i32 } define dllexport void @setGlobal(%Any* %ptr, %Any %value) { store %Any %value, %Any* %ptr ret void } define dllexport %Any @getGlobal(%Any* %ptr) { %val = load %Any, %Any* %ptr ret %Any %val } Trying to replace the setGlobal call with what should be
