1. A preprocessor

2. The compiler, which consists of the following phases:
   1. Front-end parsing and semantics handling
   2. Loop transformations
   3. Interprocedural analysis
   4. Optimization
   5. Register allocation
   6. Final assembly

3. The assembler (for any .s files)

4. The linker ld
