there was a topic crossposted to comp.lang.scheme and comp.lang.lisp
(started 18 Dec 2004) about usability of LLVM for Scheme and Lisp.
Schemers gave some replies.
if link is skewed for you, just use google's group search facility
(not beta! it has too
delayed update for new posts) or your nntp source to find this topic.
Maybe few words from LLVM team members would clear the points
...and extend LLVM' audience
