Now that cc65 programs can run as SYS files themselves my ProDOS Loader ulimately has to change from a minimalistic shell replacement to a pure loader (without exit hook). This approach simplifies several things. However the "reboot after exit" option now present as a ProDOS Loader variant has to move into the cc65 program. git-svn-id: svn://svn.cc65.org/cc65/trunk@4172 b7a2c559-68d2-44c3-8de9-860c34a00d81 2009-09-14 19:58:06 +00:00			`;`

Moved IRQ hooking / unhooking from startup code to constructor / destructor to avoid linking in the hooking / unhooking code (and callirq) for the majority of cc65 prorams not linking in interruptors. git-svn-id: svn://svn.cc65.org/cc65/trunk@5985 b7a2c559-68d2-44c3-8de9-860c34a00d81 2013-02-12 22:39:38 +00:00			`.constructor initreboot, 11`

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 20:26:22 +00:00			`.segment "ONCE"`
