Hi Guys,
I have checked in the following patch to add an arm-epoc-pe specific
linker script. This was done so that the contents of the .rdata
section could be added to the end of the .text section. which is
required by the EPOC tools.
Cheers
Nick

* Makefile.am: Fix arm-epoc-pe dependencies.
* Makefile.in: Regenerate.
* emulparams/arm_epoc_pe.sh (SCRIPT_NAME): Set to epocpe.
* scripttempl/epocpe.sc: New file: copy of pe.sc, customised for
EPOC by placing .rdata into .text.
