It was a product of its time I guess, much better ones from similar vintage,

The Tiger book (with C, Standard ML, and Java variants)

https://www.cs.princeton.edu/~appel/modern/

Compiler Design in C (freely available nowadays, beware this is between K&R C and C89)

https://holub.com/compiler/

lcc, A Retargetable Compiler for ANSI C

https://drh.github.io/lcc/

Or if one wants to go with more clever stuff,

Compiling with Continuations

Lisp in Small Pieces

Another vote for Lisp in Small Pieces. Great high level compiler book that teaches you how to build a Lisp and doesn’t get bogged down in lexing and parsing.
