IR no longer depends on VM syscalls but has its own syscall list for the few builtin functions that still require it

@ -17,7 +17,6 @@ Future Things and Ideas
^^^^^^^^^^^^^^^^^^^^^^^
Compiler:
- vm/ir: all(), any(), reverse() and sort() still depend on a VM Syscall. Get rid of this. (maybe use a IR 'builtin' function?)
- vm/ir: put variables and arrays in BSS section (unless -noreinit is specified)
- vm: Jumps go to a code block rather than a specific address(label) -> also helps future dead code elimination?
- vm: the above means that every label introduces a new code block. This eliminates the use of actual labels altogether.
@ -51,8 +50,8 @@ Libraries:
- fix the problems in atari target, and flesh out its libraries.
- c64: make the graphics.BITMAP_ADDRESS configurable (VIC banking)
- optimize several inner loops in gfx2 even further?
- add modes 3 and perhaps even 2 to gfx2 (16 color and 4 color)?
- add a flood fill routine to gfx2?
