Right.. And I brought this issue up long ago :)

clang front-end but isn't really clang (it has some features clang doesn't
have, some regular clang features are unimplemented, and the usual llvm
back-end has been replaced by IBM's as far as I know).

Yep.. And IIRC they unfortunately did not remove the llvm defs when they
striped it out.

It would be BOOST COMP EDG FRONTEND. As that follows general pattern of it
being a part / variation of a compiler.

So are EDG and clang the only frontends?

Should we also have backbend definitions?
