D - Dernel: D & interrupt handling

Hi Walter, how about adding an attribute "interrupt"? Functions marked  
with this attribute should use a IRET instead of a RET/RETF. At least for  
the X86 versions, this would make D even more interesting to system  
development.

'extern(interrupt)' would seem to make sense for this.

Why extern? But if this makes sense, why not. Robert

How about instead using inline assembler?

void my_interrupt_handler()
{
    asm
    {    naked            ;
        pusha               ;
         call    function    ;
        popa              ;
        iret                ;
    }
}

void function()
{
    ... handle interrupt ...
}

Yes, that's the workaround. Of course possible and not to hard to do. My  
ides was based on the attribute concept being included in D because I like  
approaches, that are extendable and re-use the available concepts as much  
as possible.

I'm going to use this code for now ;-)) Robert
