Pseudo-Compiler

Implements a complete PL/0 compiler in C including:

• A lexical analyzer
• A recursive-descent parser and code generator
• A stack-based PM/0 virtual machine

Files

• lex.c — used to tokenize a given set of PL/0 code (does not act on errors) results produced in tokens.txt.
• parsercodegen.c — The token parser and code generator that takes in the tokenize PL/0 code and converts to P-machine code results produced in elf.txt.
• vm.c — Virtual machine used to run the produced P-machine code and construct a stack based architecture.

Run

• gcc -O2 -std=c11 -o lex lex.c
• gcc -O2 -std=c11 -o parser parsercodegen.c
• gcc -O2 -std=c11 -o vm vm.c

Once compiled run each individually:

• ./lex input.txt
• ./parser
• ./vm elf.txt

Or can be ran through makefile

• make
• make run
• To reset: make clean

Environment

This project was developed and tested on Linux using GCC.
