llvm dev - Feb 2010 - [LLVMdev] Unpacked Structures within Packed Structures

Dear LLVMers,

I have a question on packed structures in LLVM 2.6.

Is it possible to place an unpacked structure type as a member within a 
packed structure type?  What I want to do is to have the fields of an 
inner structure padded per the ABI but have the elements of the outer 
structure packed.

Thanks in advance.

Yep, that should work fine.  One issue to watch out for is that the  
elements of the non-packed struct may not be properly aligned if the  
entire thing is off.
