My bad: I'd missed that one because I always go straight to the doc/ directory for documentation of this kind -- the root README I never read apart from the first few pages, and I would not have thought it to give this level of detail. BTW, a fix to this ./README is in order as GOT is not used any more with ELF ARM relocation, so r9 is not needed for this anymore... ... and even though I don't like the idea of reserving a register for gd, since we must for the moment, then using the (now available) r9 register would be *more* 'EABI/AAPCS-compliant' than using r8 (as I said, one could think of this use of r9 as 'our AAPCS variant').
