Compilers Project

Project Overview:

Simple C language Compiler that is designed to compile basic functions of C language components.

Tools and Technologies used:

• Flex: compile lex files
• Bison: compile yacc files
• Cygwin: generate executable files

Production rules:

• Variables and Constants declaration
• Mathematical expressions (+, -, *, /)
• Assignment statement
• Block structure ({}, ())

Quadruples:

• MOV 3, R0 [move value 3 to register R0]
• MOV R0, x [move value in register R0 to variable x]
• ADD R0, R1, R2 [add the value in R0 & R1 and move it to R2]
• SUB R0, R1, R2 [the same as ADD but subtract]
• MUL R0, R1, R2 [the same as ADD but multiply]
• DIV R0, R1, R2 [the same as ADD but divide]
