# Compilers: How To Make a Programming Language
|
||
|
||
Other compiler-related topics out of scope:
|
||
- What are programs anyway (Forth, LISP)
|
||
- Computation: Turing machines, lambda calculus
|
||
- Compiler optimization
|
||
- GC (motivated by LISP)
|
||
|
||
aesthetics:
|
||
- stay motivated; stick close to a c-like, imperative, procedural model because that's what people are used to
|
||
|
||
motivation / goals / what questions are we trying to answer:
|
||
- I want to be able to make a toy procedural language.
|
||
- like C, Algol, JS, Lua, etc.
|
||
- possible user motivations:
|
||
- I want to make a game scripting language
|
||
- I want to make a DSL for my job (and I want syntax highlighting!)
|
||
- I want to do simple static analysis of my projects
|
||
|
||
ok what do we want to cover
|
||
- classical compiler structure (lexer -> parser -> codegen)

|
||
|
||
- regular expressions?
|
||
- regular languages / grammars / language structure / automata
|
||
- terminology?
|
||
|
||
the c compilation process
|
||
- translation units
|
||
- preprocessing -> (the whole compilation process) -> object files -> linking
|
||
- c compilation model is not in favor any more, don't like compiling all these files separately
|
||
- ABIs and FFI
|
||
- should maybe be in separate article
|
||
|
||
experts / consultants:
|
||
- Bill
|
||
- NeGate
|
||
|
||
## The actual progression
|
||
|
||
- Simple expression interpreter (parse and evaluate)
|
||
- Classical compiler construction (lex -> parse -> output), semantic analysis / type checking
|
||
- motivation: complex structures! recursion! etc.
|
||
- many of these resources exist and cover different aspects of the process in different ways
|
||
- Grammars and language structure
|
||
- Types of output (interpreter vs. AOT vs. JIT, etc.)
|
||
- We can probably find resources on specific ones of these
|
||
- Modern phases (IR / SSA)
|
||
- Mention WASM?
|
||
- The terrors of the real world
|
||
- Executables, linkers, and debug info
|
||
- Also debug info
|
||
- The C ABI and FFI
|
||
- Debug info
|
||
- Codegen
|
||
- Specifically: machine code generation, of reasonable quality
|
||
- Note: not necessary for all "compilers"
|
||
- Topics: register allocation, instruction selection, instruction scheduling
|
||
- Some examples of optimization passes
|
||
- There are not a lot of resources for this. Place a public TODO here?
|
||
- Appendix:
|
||
- Grammar basics (BNF, EBNF)
|
||
- Need not go into exhaustive detail on categories of grammars
|
||
- C is not the only language
|
||
- LISP
|
||
- Forth
|
||
- This could be a whole topic maybe
