LLVM backend without jumps (no goto)

I need to write a LLVM backend for a language that doesn't support jumps (conditional or unconditional). The only flow control structures I can use are if-then-else and while loops (plus break and continue).

Is there any way (or utility) to convert from LLVM jump-based+phi-node based to this?

You can refer to the relooper algorithm in the Emscripten, which was targeting LLVM IR to javascript, and there's no "goto" statement.
