Are there any better / more modern books that cover this topic?
### Some of the following assume an advanced backround:
Structure and Interpretation of Computer Programs , Abelson & Sussman &
Engineering a compiler, K.D. Cooper & L. Torczon
Modern Compiler Design (Worldwide Series in Computer Science),
Build Your Own Programming Language: A programmer's guide to designing compilers, interpreters, and DSLs for solving modern computing problems, C Jeffery
### Alternate suggestions:
Aho et al. book covers quite a broad variety of topics/discussions. There are resources that cover more current approaches / more indepth for a given topic/specific subject matter than would be possible in Aho et.
Depending on requirements/needs, on-line resources/courses/topics can provide access to more modern/quicker feedback:
search compiler on https://www.geeksforgeeks.org/
software perspectiv, https://program-transformation.org/
research intensive, look at specific book/documentation on how a language is/was implimented, aka cpython, java, compiling lisp, smalltalk-80, forth
