- Changed the file structure of the SuB Suite, so that
all variable declarations, symbols, and constants
are in a single file.
- Moved the C library functionss into a separate
file, and made them use stack frames.
- Added support for using the emulator's assembler for
realtime debugging, to enter it, get in to stepping
mode by pressing Ctrl+s, press any other key, then
press F1,
The reason for having to press some other key before
pressing F1 is because it only allows entering the
assembler when the keyboard is not ready.
- Added the ".res" directive to the emulator's
assembler, the ".res" directive tells the assembler
to reserve however many bytes specified by the
operand.
- Fixed some bugs in the emulator's assembler.

- Added a new preifx called the OF prefix, which adds
the contents of a specific register to the current
operand.
- Added a table generator, which parses opcode table
csv files.

|
|
- Refactored the symbol, and fixup table to now use a
linked list
- Added support for local symbols to the assembler.
- Rewrote SuBEditor, and SuBAsm to use local symbols.

code duplication.
The assembler now uses pre-tokens, which are smaller
tokens, that make up the larger tokens.
|
|
The reason for doing this was because JSL, and RTL are
redundent, as they both do the same thing as JSR, and
RTS.

support for comma separated values.
The assembler now uses a linked list of tokenized
lines, each containing a linked list of tokens for
that line.
I also moved all of the large tables into the higher
parts of memory, in order to free up the lower part of
memory for the user.
Comma sepparated values only work with directives, and
only with the byte", word, dword, and qword directives.
I also added support for getting the upper, and lower
halves of an address. The tokens for both of those are
'<', and '>' respectively.

- Moved the large enums, and large tables into separate
header files.
- Added enums for implementing the base extension
- Fixed a bug in the assembler.
- Worked more on SuBAsm.

assembler.
Single quote marks works in the assembler just like
they do in C, except that it only supports a handful
of escaped characters, like '\n', and '\r'.

emulator's assembler.
And removed three pointers, and the linewrap table
from zero page, in SuBEditor.
I moved the linewrap table to address $1000.
And because of finally adding include support to the
assembler, I can now start work on SuBAsm!

emulator smaller, and faster.
I am also starting to make SuBEditor's source code
more readable.
|
|
It now has a lexer/tokenizer, along with a parser.
I have also made the emulator even smaller.
