TODO
====
For 9.0 major changes
^^^^^^^^^^^^^^^^^^^^^
- DONE: added 'cbm' block in the syslib module that now contains all CBM compatible kernal routines and variables
- DONE: added min(), max() builtin functions. For floats, use floats.minf() and floats.maxf().
- DONE: added clamp(value, minimum, maximum) to restrict a value x to a minimum and maximum value. For floats, use floats.clampf(f, minv, maxv).
- DONE: rename sqrt16() to just sqrt(), make it accept multiple numeric types including float. Removed floats.sqrt().
- DONE: abs() now supports multiple datatypes including float. Removed floats.fabs().
- DONE: divmod() now supports multiple datatypes. divmodw() has been removed.
- DONE: cx16diskio module merged into diskio (which got specialized for commander x16 target). load() and load_raw() with extra ram bank parameter are gone.
- DONE: drivenumber parameter removed from all routines in diskio module. The drive to work on is now simply stored as a diskio.drivenumber variable, which defaults to 8.
- DONE: for loops now skip the whole loop if from value already outside the loop range (this is what all other programming languages also do)
- DONE: asmsub params or return values passed in cpu flags (like carry) now must be declared as booleans (previously ubyte was still accepted).
- DONE: (on cx16) added diskio.save_raw() to save without the 2 byte prg header
- DONE: added sys.irqsafe_xxx irqd routines
- DONE: added gfx2.fill() flood fill routine
- DONE: added @split storage class for (u)word arrays to store them as split lsb/msb arrays which is more efficient (but doesn't yet support all array operations)
- DONE: added -splitarrays command line option and '%option splitarrays' to treat all word arrays as tagged with @split

How to upgrade older programs written for Prog8 version 8 or earlier to version 9.
List of new stuff in version 9
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Details of several important ones and how to convert version 8 code can be found below this list.
- added 'cbm' block in the syslib module that now contains all CBM compatible kernal routines and variables
- added min(), max() builtin functions. For floats, use floats.minf() and floats.maxf().
- added clamp(value, minimum, maximum) to restrict a value x to a minimum and maximum value. For floats, use floats.clampf(f, minv, maxv).
- rename sqrt16() to just sqrt(), make it accept multiple numeric types including float. Removed floats.sqrt().
- abs() now supports multiple datatypes including float. Removed floats.fabs().
- divmod() now supports multiple datatypes. divmodw() has been removed.
- cx16diskio module merged into diskio (which got specialized for commander x16 target). load() and load_raw() with extra ram bank parameter are gone.
- drivenumber parameter removed from all routines in diskio module. The drive to work on is now simply stored as a diskio.drivenumber variable, which defaults to 8.
- for loops now skip the whole loop if from value already outside the loop range (this is what all other programming languages also do)

- added -splitarrays command line option and '%option splitarrays' to treat all word arrays as tagged with @split
``cx16diskio`` is now just ``diskio``
