Hi Guys, I am checking in the patch below to add support for RX code which has been compiled with a Position Independent Data feature enabled. (I will be applying a patch to add this support to gcc shortly). With this enabled, constant data is accessed via offsets from a fixed register, when can be initialised at run-time. This allows constant data to be held in ROM at an address that is unknown the programmer, and without requiring that relocations be retained in the executable image. This code was written by DJ Delorie on behalf of Renesas and it is now being contributed back to the community. Cheers Nick include/elf/ChangeLog 2011-10-05 DJ Delorie <dj@redhat.com> * rx.h (E_FLAG_RX_PID): New. gas/ChangeLog 2011-10-05 DJ Delorie <dj@redhat.com> Nick Clifton <nickc@redhat.com> * config/rx-defs.h (rx_pid_register): New.
