I think you may be referring to the "clang" compiler front-end, not LLVM per se: http://clang.llvm.org/ I believe it is possible to build MacRuby with clang, though we don't take advantage of any clang-specific features since Ruby by default builds with -c99 strict mode. Clang is only about compile-time diagnostics and static analysis for C code, which is useful for people debugging the underlying implementation but not of general interest. In terms of performance, the important aspect is the LLVM back-end, which I believe we have always used. -- Ernie P. > > Bob Rice > > > On Sep 17, 2010, at 6:45 AM, Caius Durling wrote: > >> On 15 Sep 2010, at 00:00, Robert Rice wrote: >> >>> After viewing the introduction to Xcode 4 and LLVM, I am curious if MacRuby >>> compiler could be integrated into and directly compiled by LLVM.
