delcypher added a comment. I'm a little late to the review but hopefully I'll have useful comments. Nice work @ddc

FYI I've been working on floating point support in KLEE and have extended it to support floating point (note however only the Z3 backend actually supports consuming floating point constraints). I've not yet open sourced what I've done as I'm not entirely happy with the design but if there is interest we could see if we could figure out a way of pulling `klee::Expr` (and the solver bits) out of KLEE to make a standalone library. Note there is a project called `metaSMT` that uses template meta programming to give the same interface to multiple solvers. KLEE does support it but I'm not familiar with it. Also using Z3's C interface is the way to go. We also use this in KLEE. https://reviews.llvm.org/D28952 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
