Summary

1And in Conclusion$\dots$¶

We spent one chapter covering one figure:

• The Compiler converts a single high-level language file into a single assembly language file.

• The Assembler removes pseudoinstructions, converts what it can to machine language, creates checklist for the linker (relocation table).

  • These details are stored in an object file.

  • The assembler does 2 passes to resolve addresses in the text segment, handling internal references to position-independent code.

• The Linker combines several .o files and resolves absolute addresses.

  • The linker enables separate compilation, libraries that need not be compiled, and resolves remaining addresses (more details)

• The Loader loads executable into memory and begins execution.
