[LLVMdev] LLVM and Interrupt Service Routines.

[Alex Karahalios]

Hi Sanjiv,

Assuming that that support for Ada in LLVM is complete, I would look  
to see if there is something that is done there. Ada provides two  
pragmas (Interrupt_Handler & Attach_Handler) which allow you to both  
statically and dynamically attach interrupts to procedures.
