cuteC-compiler

cuteC-compiler (Come Undo Those Exceptions-C Compiler) is a mini-version (implementing a drop from the ocean that is C) of a C-compiler written in C for MIPS architecture.

How to run?

Run these commands in the root directory of the repo:

Compiling cuteC

make

Running tests

./a.out<test/testFile.c

Open asmb.asm file in Mars. Assemble and Run.

Features:

• Supports int datatype (positive and negative integers both)
• Arithmetic operations: + - / * %
• Relational operators: == != > < >= <=
• Logical operators: && ||
• Single line and Multiline comments:
• Variable declaration and assignment (local)
• Supports printf() syscall
• Supports while loops
• Supports for loops
• Supports nested loops
• Supports if, else if, else statements (nested ifs)
• Verbose error reporting with line number
• Unterminated multiline comments reported as error
• Can return arithmetic expressions (like a+b) or logical expressions (like a>b)

Things to look out for

• Program should have exactly one int main() function.
• Only one return statement that terminates the program. Return value is printed out.
• Declare all variables to be of type int
• Multi-operand arithmetic and logical expressions follow BODMAS precedence rule
• For loop should follow the format: for (i=0;i<10;i=i+1)
• For loop works in the same scope as the main function. So, same variable names cannot be reused inside the for loop.
