p-code-machine-C

An implementation of a simple P-code machine using C.

Available Instructions

The project is still in progress, for now it supports the following instructions:

• LIT
• OPR
  • RTN OPR 0 0
  • ADD OPR 0 2
  • SUB OPR 0 3
  • MUL OPR 0 4
  • GTR OPR 0 12
• LOD
• STO
• CAL
• INT
• JMP
• JPC

#Compilation ####Linux Just run the 'make' command on a linux terminal from the main folder, it should be good to go. ####Windows Copy and paste on a prompt (from the Makefile folder):

gcc -o main src/main.c src/parsing.c src/pcode.c src/error.c -Wall

#Running The machine must run over a specified input file, containing the instructions:

./main examples/t1
or
main.exe examples/t

#Examples I've included some examples to test and see how the machine operates. Currently there's a step-by-step execution

####examples/t1 file Sums 2+3 ####examples/t2 file Subtracts 20 by 5 until gets to 0 ####examples/t3 file Sums 8+2

If you want to create your own examples, try to follow the current format (no newlines or extra spacing), as it may not work properly. AND PAY ATTENTION TO INFITE LOOPS, luckly you can interrupt them witl CTRL + C.

Reference code

Another implementation Could not run it, and found some errors, but I'm just using for some more coding references (good job btw).
