...question is simply why LLVM does not use the notion of trap representation of C11 standard to represent the undefined value, rather than using the set-based semantics. We'd like to understand the motivation of the set-based semantics over the trap representation. Thanks.

Reed, Are you working on a grammar of the LLVM syntax or also on a full semantics? Steve Zdancewic's group at U. Penn. is working on a formal operational semantics for LLVM. It is partially complete and Greg Morrisett at Harvard is planning to build further on it.
