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? > Best regards, > > Wolfgang Denk Amicalement, -- Albert. _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
