OTBP Assembler 1

calc84maniac · Posted: 08 Sep 2006 04:22:00 pm Post subject: OTBP Assembler 1

I am thinking about making an compiler on-calc similar to TASM oncalc. I just made an asm program that will copy program data into a string (even if it's archived Wink

), and I'm wondering if anyone has any good compiling techniques I could use.

BTW, I'm going to try to accomplish relative addressing.

Update: Now at v1, here's the link
Features so far:

File types:

Source files
Include files
Includable headers
Supports archived files
Immediate values:
Decimal
Binary
Hexadecimal
Equates
ASCII
Assembling:
ix/iy can be used wherever hl can
(ix/iy +/- value) can be used wherever (hl) can
Supports jr/djnz
Many commands are included in the main program to save space
Memory-saving techniques are used while compiling
Skips empty lines
Supports Ion/MirageOS/DCS6
Comments
No case sensitivity
Brackets no longer needed
Error catching
Coming Soon...
Ideas, please?

I will add more to the list when I have time.

What sort of compiler? A Z80 compiler? Some new language? Why store it to a string?

A Z80 compiler (after all, this is the Z80 asm forum).
The main compiler will be in BASIC, so it will copy the source and include files to strings to manipulate them easier.

You are trying to make a Z80 compiler in BASIC? I'd reconsider that in a hurry, and make the compiler in ASM, too

So, you decided to learn ASM?

Sounds good, except the part about it being mainly in basic, but I didn't learn enough ASM to be of much use to you here...

Not sure how you'll do it.

Good luck creating it and I hope you can complete it.

Wow, there are 15 users online: 8 members, 2 guests and 5 bots!!! Earlier, there were still 15 users, but only 3 bots (4 guests).

The TASM oncalc guy accomplished it in BASIC, and I'm trying to make a better version.

Edit: Please notice my request for good techniques, it seems that everyone's missed that.

The biggest challenge with oncalc ASM is text labels and the equates table, for example _clrgrbuf = NNNNh. With a lot of labels, the compilation tables far exceed the amount of RAM even an empty z80 has.

You *could* potentially get around that by making several tables, and using the first letter or two as a table index.... I think that would work, although it would still take up alot of archive space

Success! The only things mine doesn't support now are:

set/res/bit
binary

And maybe a couple others that I forgot.
Program size: 2077

I'll attach the files if someone tells me how (so you can beta test it).

Never mind, I figured it out on my own.
Here's the link.
I assume no responsibility for any RAM resets.

Okay. BTW, here are the built-in commands: (no include file needed for these)
ld 8-bit-reg,
add a,
adc a,
sub
sbc
and
xor
or
cp

Could you post the source code?

What is zcompile?

It's the asm subroutine.
Inputs:
String: Copies program whose name is in string into Str0.
Otherwise: Returns the ASCII code for whatever is at row 7, col 1. (For use with .db)
