[PATCH 1/8] or1k: Callee-saved registers for permanent data
Sun May 17 14:59:00 GMT 2015
this is the first of a set of patches for the or1k libgloss, essentially
some small bug fixes.
Thanks in advance!
During interrupt handling the PICSR, table pointers and current
interrupt line have been saved in incorrect registers and/or stored on
Save the pointer in r16/r18, PICSR in r20 and the current interrupt
line in r22. Those are callee-saved registers, so that the register
values will be preserved.
* or1k/interruts-asm.S: Change registers to callee-saved
