Rustc Dev Guide WG 2019-05-14 sync meeting

Topics discussed:

  • Define what’s the walkthrough section we want to add
  • Triage missing rustc-dev-guide chapters
  • How do we want to keep track of who is doing what? Does github Projects works nice for this?

Plan for walkthrough/overview chapter

  • Goal is to have a chapter which will walk through compilation of simple program
  • Links to other chapters for details
  • This overview differs from the existing queries chapter in that the latter is more focused on how to create your own queries.

Status: - lokalmatador is giving this a try & will open a PR at some point

rustc-dev-guide missing chapters

Topics that need to be added

  • Monomorphization, Type Memory Layout, Codegen, LLVM
  • Macros, hygiene, proc macros, custom derives, etc.
  • Lexing and Parsing
  • Walkthrough of a typical contribution
  • The rest of
    • Name Resolution
    • Traits
    • Region Constraints
    • SLG solver
    • Type checking
    • MIR
    • Constants, Promoted Constants in MIR
    • Construction of MIR
    • Optimizations
    • Borrow Check: Moves and initialization
    • MIR Type check
    • Various parts of NLL
  • A large collection of potential improvements in the form of issues on the repo

Status:

  • Would be good to schedule a lecture on each missing topic
  • less work for the experts
  • Can then transcribe into a chapter
  • @spastorino will arrange lectures, nikomatsakis will create zoom

How do we want to keep track of who is doing what? Does github Projects works nice for this?
