As for compiler resources, I've put a respectable dent in  and so far I've found it to be pretty accessible.
"The compiler we construct accepts a large subset of the Scheme programming language and produces assembly code for the Intel x86 architecture, the dominant architecture of personal computing. The development of the compiler is broken into many small incremental steps. Every step yields a fully working compiler for a progressively expanding subset of Scheme. Every compiler step produces real assembly code that can be assembled then executed directly by the hardware."
"We do not assume that the reader knows anything about assembly language beyond the knowledge of the computer organization, memory, and data structures. The reader is assumed to have very limited or no experience in writing compilers."
Have a look at the books and compilers at http://t3x.org.
For a first glance, I would recommend https://t3x.org/t3x/book.html. If you are only interested in the source code, it is in the public domain and can be downloaded on that page.
I took Alex Aiken's course in my first year when I started to learn writing code, was feasible back then and pretty interesting.
