Memory Block Operations integrated in language?
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
list,string memory block operations?
|
|
|
|
- list operations (whole list, individual element)
|
|
operations: set, get, copy (from another list with the same length), shift-N(left,right), rotate-N(left,right)
|
|
clear (set whole list to the given value, default 0)
|
|
|
|
- list operations ofcourse work identical on vars and on memory mapped vars of these types.
|
|
|
|
- strings: identical operations as on lists.
|
|
|
|
these should call optimized pieces of assembly code, so they run as fast as possible
|
|
|
|
For now, we have the ``memcopy``, ``memset`` and ``strlen`` builtin functions.
|
|
|
|
More optimizations
|
|
^^^^^^^^^^^^^^^^^^
|
|
|
|
Add more compiler optimizations to the existing ones.
|
|
|
|
- on the language AST level
|
|
- on the final assembly source level
|
|
- can the parameter passing to subroutines be optimized to avoid copying?
|
|
- working subroutine inlining (taking care of vars and identifier refs to them)
|
|
|
|
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
|
|
without having to to index into the stack?
|
