Currently, the compiler doesn't generate code for rules and strategies that are never called. With dynamic loading, a program/module can have multiple entry points, and the compiler needs to ensure that code is generated for all of them and that their symbols are exported.

A simple hack would be to add a --dynamic-main which would name the main entry point. This would take care of the simple case were a loadable module has only one entry point (which is different from the normal main).

A better solution would be to provide some sort of 'export' declaration; which we'll probably need anyway for the module system. For example,

export s = foo + bar

or

exported strategies

 s = ...

STR-365, visser:
This isssue is (temporarily) solved by the DYNAMIC-CALLS hack from issue STR-346. A cleaner solution should be designed eventually. Therefore, leaving this issue open (but moving it to a future release).

The --library option also disables the dead code elimination optimization. Note that strategies that are marked internal can still be eliminated in this case, and are not exported to other libraries.
