Comment by sieve

I got started from the books that were available here in the early 2000s. The one I like the most is "Programming Language Pragmatics" by Michael Scott, mainly for its simplicity. Then there is "Advanced Compiler Design and Implementation" by Steven Muchnick. I have Allen-Kennedy's book too, but I think it went over my head when I went through it. So I kept it aside.

"Engineering a Compiler" is quite approachable.

But, once you know the basics, you get the best bang-for-the-buck by looking at source code of various compilers and virtual machines.
