<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>
