 Well, then it seems there is no easy way to specify this behavior 
directly in the C code. I was trying to use the assembly file as the last 
resort. Calling external functions from the ISRs have a little performance 
hit in my application, perhaps I will end up duplicating code or rewriting 
my code for inlining...

 Some compilers use pragmas to specify absolute code positioning and mark 
ISRs. I know this is not an elegant way, but plain C is a little bit weak 
in this kind of situation. Also, I wish there were an easier way to modify 
the vector table (using, eg, an attribute mark). I am relatively new to 
this list -- have any other methods been considered?

 Thank you for your responses.

 Cheers!
