Double-pass assembler, written in ANSI C90 for an imaginary 24-bit computer.

It's awesome to have you here 🤩

I'm into it, as long as it makes me think.

openu-c-project's Issues

TASKS LEFT TODO

TODO

• 1.1 Set IC=100, DC=0

• 1.2 Read first line, skip to 1.17 if done

• 1.3+1.4 Is symbol? set flag

• 1.5+1.6 if .data or .string, store the symbol with DC in data table (error if already exists).

• 1.7 encode the data into the data array,, andi increase DC by the length needed (increase by 1 for each data section (char/number))

• 1.8+1.9+1.10 if extern, inert the symbol into extern table. read next line.

• 1.11 otherwise, it's instruction. insert symbol if there's one to the code table

• 1.12 check if it's valid command (like add, jmp..). if not, make sure an error is printed!

• 1.13 analyze the operand structure of the command

• 1.14 Build the binary code of the first instruction's word, and every other immediately-encoded data value (#)

• 1.15 Keep the values of L & IC for next stage

• 1.16 update IC=IC+L

• 1.17 Print any error f found and halt the program

• 1.18 Save IC as ICF and DC as DCF

• 1.19 Increase each .data value by ICF

• 1.20 Start 2nd pass

• 2.1 read next line, if done skip to 7

• 2.2 if label (symbol) skip

• 2.3+2.4+2.5 if entry, add it to entries table (only if exists in code table!)

• 2.6 complete replacement by symbols

• 2.7 stop and print errors

Make sure error messages in error tests are all printed correctly

Make sure that there's no symbol twice, Except in externals

a little help with c project

hi there!
I saw your final project from three years ago (מעבדה בתכנות מערכות), and I was wondering if I can get some help on how to do this project.
I've read all the instructions and seen multiple lectures explaining the project and even though I understood all of what was explained I still have no idea how to start and what to actually write in code and where to begin. I was hoping you might be able to help me.
I am also willing to pay you if you want if you can write the project for me, the due date is August 11, so there isn't much time left if at all.
thank you regardless.

Externals should be fixed!

Move all string-related macros & constants to input_helper.h

CMP instruction doesn't have the appropriate length property in code image

Blank line at end holds the previous line and therefore it is being processed
