[cfe-dev] CGRecordLayout: what difference should be between types returned by getLLVMType and getBaseSubobjectLLVMType

[Evgeny Astigeevich]

Hi all,

 

I see that CGRecordLayout has two member functions:

 

llvm::StructType *           getLLVMType () const

llvm::StructType *           getBaseSubobjectLLVMType () const

 

The second one is used only by EmitNullConstant when the parameter
asCompleteObject is false.

 

What kind of type should the function getBaseSubobjectLLVMType return?
Should it always be less or equal to the type returned by getLLVMType?

 

For one of my tests I have that getBaseSubobjectLLVMType returns a bigger
packed version of the type returned by getLLVMType. It is bigger because
padding has been added.

 

Kind regards,

Evgeny
