* Compiler bootstrapping
|
||||
|
||||
This section contains notes about compiler bootstrapping, the
|
||||
history thereof, which compilers need it - and so on:
|
||||
|
||||
** C
|
||||
|
||||
** Haskell
|
||||
- self-hosted compiler (GHC)
|
||||
|
||||
** Common Lisp
|
||||
CL is fairly interesting in this space because it is a language
|
||||
that is defined via an ANSI standard that compiler implementations
|
||||
normally actually follow!
|
||||
|
||||
** Python
|
||||
|
||||
* A note on runtimes
|
||||
Sometimes the compiler just isn't enough ...
|
||||
|
||||
** LLVM
|
||||
** JVM

1. Hardware trust has been discussed here a bunch, most recently
|
||||
during the puri.sm talk. Hardware trust is important, as we see
|
||||
with IME, but it's striking that people often take a leap to "I'm
|
||||
now on my trusted Debian with free software".
|
||||
|
||||
Unless you built it yourself from scratch (Spoiler: you haven't)
|
||||
you're placing trust in what is basically foreign binary blobs.
|
||||
|
||||
Agenda: Implications/attack vectors of this, state of the chicken
|
||||
& egg, the topic of reproducibility, what can you do? (Nix!)
|
||||
|
||||
2. Chicken-and-egg issue
|
||||
|
||||
It's an important milestone for a language to become self-hosted:
|
||||
You begin doing a kind of dogfeeding, you begin to enforce
|
||||
reliability & consistency guarantees to avoid having to redo your
|
||||
own codebase constantly and so on.
|
||||
|
||||
However, the implication is now that you need your own compiler
|
||||
to compile itself.
|
||||
|
||||
Common examples:
|
||||
- gcc builds with gcc
