Rust C Compiler (rcc)

About

rcc is a toy C compiler written in Rust (In Progress). This compiler is inspired by the article - Writing a C Compiler. Tests are taken from the author's repository.

Usage

This program will output x64 Assembly in Intel syntax. Given the c program below as the first argument, rcc will emit the assembly language to stdout.

// test.c
int add(int a, int b) {
    return a + b;
}

int main() {
    int sum = add(1 + 2, 4);
    return sum + sum;
}

$ cargo run test.c > test.s
$ gcc -o test test.s && ./test
$ echo $?
14

4. Assignment Operator
   • Assignment (=)
   • Add and assign (+=)
   • Subtract and assign (-=)
   • Multiply and assign (*=)
   • Divide and assign (/=)
   • Modulo and assign (%=)
