IIUC, Chris suggested something like following ...

header:
  br i1 %x, label %then, %label endif
then:
  ...
  br i1 %y, label %loop_exit, label %header, !loop_pragma !1
endif:
  ...
  br i1 %z, label %loop_exit, label %header, !loop_pragma !2
loop_exit:
  ret i32 1


Where !1 and !2 are the metadata for your loop pragma.
