If the difference in size is marginal, then I prefer the implementation 
that has the least 'quirks' and most closely complies with EABI/AAPCS.

BTW your quick'n'dirty test puts GD at a fixed location identical for 
code running before and after relocation, right? But do we not change 
the stack location?
