             Bug #: 50187
           Summary: Interrupt handler attribute for x86/x86_64
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: inline-asm
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: christian.gnu@juner.de


I think it would be nice to have a function attribute that tells gcc to omit
the function prologue/epilogue, to be able to write tings such as interrupt
handlers. See the description of different compiler implementations here:
<http://wiki.osdev.org/Interrupt_Service_Routines>.
