0.6-PRE
|
|
|
|
-------
|
|
|
|
|
|
|
|
* Added `routine` and `vector` types, and `copy` instruction.
|
2015-10-19 18:17:27 +00:00
|
|
|
* Both routines and vectors can declare `inputs`, `outputs`, and `trashes`,
|
|
|
|
and these must be compatible to assign a routine or vector to a vector.
|
2015-10-22 08:56:45 +00:00
|
|
|
* Added `goto` (tail call) instruction, jumps to routine or through vector.
|
2015-10-22 18:20:48 +00:00
|
|
|
* `call` can call a subroutine indirectly, via a vector.
|
2015-10-22 08:56:45 +00:00
|
|
|
* Routine name is now shown in analysis error messages.

|
|
|
|
|
|
|
* Added `byte table` type locations and indexed addressing (`+ x`, `+ y`).
|
2015-10-18 17:47:47 +00:00
|
|
|
* Integer literals may be given in hexadecimal.
|
2015-10-18 17:54:28 +00:00
|
|
|
* Line comments may be included in source code by prefixing them with `//`.

|
|
|
* Added `repeat` loops to the language, which can repeat until a flag
|
|
|
|
is set (or `not` set), or which can repeat `forever`.
|
|
|
|
* `if not` inverts the sense of the test.
|
|
|
|
* Added explicitly-addressed memory locations.

* Added external routine declarations.
|
|
|
|
* Added ability to compile to 6502 machine code and output a `PRG` file.

A complete reboot of SixtyPical 0.1. The reference implementation was
|
|
|
|
rewritten in Python. The language was much simplified. The aim was to get the
|
|
|
|
analysis completely right before adding more sophisticated and useful features
|
|
|
|
in future versions.
