OS Running Source Code

Important pre-reading

It’s important to read up on OS Memory Management (x86), (MIPS) Assembly Language The Stack’s Use in MIPS, C (Programming Language)

How Does C Code Run?

1. The compiler turns C code into assembly code.
2. The assembler converts assembly code into machine code.
3. The Linker takes required libraries and adds it to a single final executable.
4. The loader sets up Address Space in memory and loads the first instruction into memory.
5. The CPU interprets the instructions, with %eip doing the job of the PC - Program Counter in MIPS.
