<DIV><FONT face=Arial size=2>Apparently, there is no explicit support for ISRs
in the llvm framework. I could not find a matching attribute that can be
used to mark a function as an ISR, which codegen and optimizer can use
accordingly. ISRs aren't called explicity from any function, so currently the
optimizer deletes them. We are planning to introduce a new "interrupt" attribute
(to be modeled similiar to "section" attribute) which one can use in different
passes suitably.</FONT></DIV>
<DIV>How does that sound? Or do we have something available already?</DIV>
