Compiling an assembly source on Mac OS and converting file to object/executable

I'm very new to programming and I had a question about compiling of assembly language on Mac OS. I know that to convert my .c to an .s I should use gcc -m32 -S. However, I already wrote my own .s file. I was wondering if it was possible to convert the .s I've made so that my Mac can compile it. The thing is I want to compile both the .c and .s to verify that they both return the same value.
