I think that just letting LLVM do the packing will probably be what you want. The cases where the C front-end needs to manually hack on things are for bigfields, explicit alignment attributes, etc, which I don't think Java has (correct me if I'm wrong)! LLVM uses very simple layout rules, basically inserting padding before each structure element to bring it to its natural alignment. The alignment of a struct is the maximum of the alignment of...

Hi all I'm writing a direct llvm backend for gcjx a new java fronted for gcc. I'm now ready to tackle creating the structures to represnt classes I read the gcc 4.0 patches and it seems that the llvm struct is padded and aligned using the info from the gcc tree. In my case I don't have this information. I'm willing to intially let llvm align and pad the struct but its not clear
