Hello!
I'm not a subscriber of this mailing list, so please send any replay directly to my address too.
I'm quite experienced in using the GNU-tools to develop C-applications for embedded systems based on Hitachi SH2 microcontrollers.
Now I have to do the same work on a system based on a Motorola MPC56x controller, but I encountered some difficulties.
So, I would like to ask some questions:
1) - Why is the #interrupt directive ignored by the PowerPC version of GCC?
2) - Is it possible to write an interrupt service routine in pure C language?
3) - Is there any prologue/epilogue code to be written for interrupt service routines?
4) - Where can I find some information specifically on programming embedded PowerPC systems using GCC compiler?
5) - And information about GCC and EABI compliance?
6) - And information about GCC and DWARF2 debugging information?
Some usefull links may suffice.
Thanks in advance for any hint. Michael
