Interrupts failing in 4.2-8 but had working in 4.1-32

[Mark Butcher]

Hi
There are some uTasker users who's projects are based on CodeSourcery
GNU.
Some registers users have 4.2.15 and found that the project would no
longer run but immediately crashes due to an address error.
Therefore I have just downloaded the 4.2-8 Lite (which is probably
4.2.15 like) to see what happens and it is the same on my M52235 board -
the reference project doesn't run.
 
The reason that I see is that the interrupt routines are trying to
return using RTS (rather than RTI) which result in instant death.
 
Can anyone explain why the __attribute__((interrupt_handler)) is no
longer recognised and how to get around the problem?
In the 4.1-32 Lite version we never had this problem.
 
Best regards
 
Mark Butcher
