I started on a prototype of the #ifdef one here: ⚙ D150325 WIP: Prototype #ifdef-enforced DEPENDS on tablegen output
To simplify things, I limited it to just clang/Driver/Options.inc. I’ll admit my cmake-fu is not strong enough to completely understand @chapuni’s suggestions, and I had to make some concessions:
- does not support transitive dependencies
- the relationship between the new tablegen flag and
add_public_tablegen_target’s argument isn’t automatic
Suggestions and/or more concrete advice are extremely welcome.
