/* Rust's build process has a few quirks :
|
|
|
|
- It requires some patched in llvm that haven't landed upstream, so it
|
|
compiles its own llvm. This might change in the future, so at some
|
|
point we may be able to switch to nix's llvm.
|
|
|
|
- The Rust compiler is written is Rust, so it requires a bootstrap
|
|
compiler, which is downloaded during the build. To make the build
|
|
pure, we download it ourself before and put it where it is
|
|
expected. Once the language is stable (1.0) , we might want to
|
|
switch it to use nix's packaged rust compiler.
