- remove statements after an exit() or return
|
|
|
|
|
- fix warnings about that unreachable code?
|

- aliases for imported symbols for example perhaps '%alias print = c64scr.print'
|
2020-02-09 00:21:23 +00:00
|
|
|
- option to load library files from a directory instead of the embedded ones

array/string memory block operations?

- vector inc/dec/add/sub/mul/div...? (on array or string):
|
2020-03-14 14:19:03 +00:00
|
|
|
``arrayvar++ / arrayvar-- / arrayvar += 2 / arrayvar -= 2 / arrayvar *= 3 / arrayvar /= 3``

- array operations
|
|
|
|
|
copy (from another array with the same length), shift-N(left,right), rotate-N(left,right)
|
|
|
|
|
clear (set whole array to the given value, default 0)

- array operations ofcourse work identical on vars and on memory mapped vars of these types.

|

|
|
2019-08-18 12:18:46 +00:00
|
|

- strings: identical operations as on array.

For now, we have the ``memcopy`` and ``memset`` builtin functions.

More optimizations
|
|
|
|
|
^^^^^^^^^^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
Add more compiler optimizations to the existing ones.
|
|
|
|
|
|
|
|
|
|
- on the language AST level
|
|
|
|
|
- on the final assembly source level
|
2019-01-29 22:32:43 +00:00
|
|
|
- can the parameter passing to subroutines be optimized to avoid copying?
|
2019-08-11 08:44:58 +00:00
|
|
|
- working subroutine inlining (taking care of vars and identifier refs to them)
|
2019-01-24 01:43:25 +00:00
|
|
|
|
|
|
|
|
Also some library routines and code patterns could perhaps be optimized further

Eval stack redesign? (lot of work)
|
|
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
The eval stack is now a split lsb/msb stack using X as the stackpointer.
|
|
|
|
|
Is it easier/faster to just use a single page unsplit stack?
|
|
|
|
|
It could then even be moved into the zeropage to greatly reduce code size and slowness.
|
|
|
|
|
|
|
|
|
|
Or just move the LSB portion into a slab of the zeropage.
|
|
|

Allocate a fixed word in ZP that is the TOS so we can always operate on TOS directly
|
2019-01-29 22:48:26 +00:00
|
|
|
without having to to index into the stack?
