I'm looking for advice on how to debug and fix PR50906:
The basic summary is that GCC is generating bad unwinder information or
is incorrectly saving registers onto the stack on PowerPC e500v2. Any
ordinary function call+return works fine, but exception handling fails
miserably trying to unwind the stack (as does GDB).
I have not yet been able to figure out if it's a libgcc issue or an
actual compiler issue.
Any advice would be highly appreciated.
If someone would like to help, I can walk you through a quick e500v2
qemu test-harness setup on an amd64 system.
Curious about my work on the Debian powerpcspe port?
