This repository contains the toy-compiler created as part of requirements for the course CS F363: Compiler Construction at BITS Pilani, Pilani Campus in Spring 2023 under Dr. Vandana Agarwal. Our team (Group 2) scored the highest among all groups which were part of the course.

- The language
ERPLAGis a strongly typed language with primitive data types as integer and floating point. - It also supports two other data types: boolean and arrays.
- The language supports arithmetic and boolean expressions.
- The language supports assignment statements, input/output statements, declarative, conditional, iterative, and function call statements.
- The language supports the modular implementation of the functionalities.
- Functions can return multiple values. The function may or may not return a value as well.
- The scope of the variables is static and the variable is visible only in the block where it is declared.
- Ensure you have
gcc, version 5.0 or greater, installed.
gccversion can be checked viagcc --versioncommand on terminal.
- Ensure you have
nasm, version 2.14.02 or greater, installed
nasmversion can be checked vianasm --versioncommand on terminal. You can installnasmviasudo apt install nasm
makefile has been provided with the code along with some sample test cases.
Run the following commands.
$ make
// The output to this should be
gcc -c -g driver.c
gcc -c -g parser.c
gcc -c -g lexer.c
gcc -c -g trie.c
gcc -c -g stackADT.c
gcc -c -g Set.c
gcc -c -g ast.c
gcc -c -g symbolTable.c
gcc -c -g intermedCodeGen.c
gcc -c -g codegen.c
gcc -Wall driver.o parser.o trie.o lexer.o Set.o stackADT.o ast.o symbolTable.o intermedCodeGen.o codegen.o -g -o compilerOnce all the files have been compiled correctly, run
$ ./compiler <testcase.txt> <outputFile.asm>To run the .asm file, use this command
$ nasm -f elf64 <outputFile.asm> -o code.o && gcc -no-pie code.o -o code
$ ./code<<<driver program>>>
