-/// It can either directly parse the binary bitcode file, or use LLVM routines
-/// to parse a textual bitcode file into LLVM IR and then convert LLVM IR into
-/// ICE. In either case, the high-level ICE is then compiled down to native
-/// code, as either an ELF object file or a textual asm file.

Reflow to 80-col.  (Pretty sure LLVM can fit at the end of this line.)

Done.
