Hi Alexandra, I'm not sure want you want to do. Is the data layout string (http://llvm.org/docs/LangRef.html#datalayout, also usually set by each target specific *TargetMachine constructor), for setting the alignment good enough for you? Or is it more than the alignment you want to control? Do you have a target with 16-bit bytes? In that case, there is quite a lot of changes that needs to be

Hi, I would like to force the minimum number of bits allocated for a variable in memory to be 16. From what I have seen, i1 is already represented on 8 bits. So, the only change would be to represent i1 and i8 on 16 bits, as all other types already fulfill this condition. TargetData can help by setting a higher alignment, thus although the type is i1 or i8, the number of allocated bits is 16.
