What is IL65?
|
|
-------------
|
|
|
|
IL65 is an experimental compiled programming language targeting the 8-bit
|
|
`6502 <https://en.wikipedia.org/wiki/MOS_Technology_6502>`_ /
|
|
`6510 <https://en.wikipedia.org/wiki/MOS_Technology_6510>`_ microprocessor.
|
|
This CPU is from the late 1970's and early 1980's and was used in many home computers from that era,
|
|
such as the `Commodore-64 <https://en.wikipedia.org/wiki/Commodore_64>`_.
|
|
The language aims to provide many conveniences over raw assembly code (even when using a macro assembler),
|
|
while still being low level enough to create high performance programs.

Design principles
|
|
-----------------
|
|
|
|
- It is a cross-compilation toolkit running on a modern machine.
|
|
The resulting output is a machine code program runnable on actual 8-bit 6502 hardware.
|
|
- Based on simple and familiar imperative structured programming paradigm.
|
|
- Allowing modular programming: modules, code blocks, subroutines.
|
|
- Provide high level programming constructs but stay close to the metal;
|
|
still able to directly use memory addresses, CPU registers and ROM subroutines
|
|
- No dynamic memory allocation. All variables stay fixed size as determined at compile time.
|
|
- Provide various quality of life language features specifically for the target platform.
|
|
- Provide a convenient edit/compile/run cycle by being able to directly launch
|
|
the compiled program in an emulator and provide debugging information to the emulator.
|
|
- The compiler outputs a regular 6502 assembly code file, it doesn't assemble this itself.
|
|
A third party cross-assembler tool is used to do this final step.
|
|
- Goto is considered harmful, but not here; arbitrary control flow jumps are allowed.
