Just how much can llvm be used?

First let me admit that I'm completely uninformed here!

1. Will llvm produce errors if llc is used to compile itself?
2. Will make produce subsequent errors if compiled first by llc/llvm?
3. Can llc be used to compile the entire Linux toolchain?

If by these two questions you mean "can LLVM self-host" (i.e., GCC
compiles LLVM and that LLVM then compiles LLVM) and runs without
(known) errors, then yes.
