I want to know how can I do to make a C interrupt handler ( which uses primary registers )
interrupt correctly an assembly routine ( which uses alternate registers ). 

I've the following problem :
Functions "Interrupt handler" ( interrupt(), interrupts() .. ) offered by visualDSP
don't swap into primary register. Then , when an assembly is interrupted, the interrupt handler
save the context with the active alternate registers (  i6 frame pointer and I7 stack pointer
are wrong ).

Should I do my own interrupt handler ?

Does anybody have an idea ?

Thank you.
