Hi,
This fixes PR target/50106 which was missing handling return register
size from 1-3 for Thumb1. Fixed thusly. Final testing on-going with
arm-linux-gnueabi with thumb1.
Ok to backport to 4.6 branch given it is branch freeze time ? I'll be
able to commit this to the branch latest by tomorrow A.M. UK time.
cheers
Ramana
