Writing a C Compiler: Build a Real Programming Language from Scratch

Real Programming Scratch: Writing a C Compiler is a hands-on book about building a compiler for a significant subset of C. It walks through lexing, parsing, program analysis, x64 assembly generation and optimization, with algorithms presented in pseudocode so readers can implement them in a language of their choice.

At a glance

Build a working compiler for a significant subset of C, adding features chapter by chapter.
Covers lexing, recursive-descent parsing, abstract syntax trees and program analysis.
Explains translating C constructs into x64 assembly, including arithmetic, function calls and control flow.
Discusses constant folding, dead store elimination and register allocation.
Algorithms are provided in pseudocode, allowing implementation in a language of the reader’s choice.

Pros and cons

Pros

Project-based treatment connects compiler concepts to building a working compiler.
The book covers both front-end topics and code generation and optimization.
The pseudocode approach does not require implementing examples in a single specified language.

What to know before buying

The description says no prior experience with compiler construction or assembly is needed, but it does not state prerequisites for programming or C. The compiler targets a significant subset of C, not necessarily the complete language.

Who is it for?

A good fit for

Programmers who want to learn compiler construction by building a C compiler.
Readers interested in lexing, parsing, program analysis and x64 code generation.
Learners who prefer project-based explanations and want to implement algorithms in their preferred language.

Less suited to

Readers seeking a reference covering the complete C language or every compiler architecture.
Buyers looking for a guide focused only on using an existing compiler rather than creating one.

The supplied evidence contains aggregate ratings but no written customer-feedback summary, so it does not establish what readers praised or criticized. The ratings are generally favorable but include a notable middle-rating share. Treat them as a broad impression rather than evidence about specific aspects such as the pseudocode, technical depth or suitability for a particular background.

Frequently asked questions

Does the book cover the complete C language?

The listing describes a compiler for a significant subset of C. It does not claim complete coverage of the language.

Do I need prior compiler or assembly experience?

The description says no prior compiler-construction or assembly experience is needed. It does not specify programming-language prerequisites.

Can I implement the compiler in a language other than C?

The algorithms are presented in pseudocode, and the description says readers can implement the compiler in whichever language they like.

Which compiler topics are covered?

The listing names lexing, recursive-descent parsing, abstract syntax trees, program analysis, x64 assembly code generation and optimization techniques.
