Ada provides two pragmas (Interrupt_Handler & Attach_Handler) which allow you to both statically and dynamically attach interrupts to procedures.

Hi, 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

As such, I guess calling conventions and so forth are not very relevant for it :) In any case llvm-gcc and gcc mainli...
