Added empty IRQ backend. The driver kernels all require IRQ handling even if the actual drivers don't make use of it. So in order to successfully link a NES program using the joystick and/or TGI driver there has to be at least a "dummy" IRQ backend. 2015-07-22 11:36:39 +02:00			`;`

Renamed INITBSS to INIT and INIT to ONCE. The way we want to use the INITBSS segment - and especially the fact that it won't have the type bss on all ROM based targets - means that the name INITBSS is misleading. After all INIT is the best name from my perspective as it serves several purposes and therefore needs a rather generic name. Unfortunately this means that the current INIT segment needs to be renamed too. Looking for a short (ideally 4 letter) name I came up with ONCE as it contains all code (and data) accessed only once during initialization. 2016-03-06 21:26:22 +01:00			`.segment "ONCE"`
