Libcore doesn't use the (entire) libc runtime; IIRC, it essentially just needs the memcpy and memset symbols to be defined.

  Couldn't it use librlibc then?
  • dbaupp 12y ago
    Yes, that's exactly what librlibc is for and what is used.

  Why not just implement those in Rust too? It seems like you could break the dependency entirely.
  • pcwalton 12y ago
    You can implement those in Rust if you want.
  • dbaupp 12y ago
    Yes, you can, and they are even provided in pure Rust for exactly that reason: http://doc.rust-lang.org/master/rlibc/ http://doc.rust-lang.org/master/rlibc/ (Seems there were 2 more mem* symbols required than I remembered.)
