Ellsif compiles and runs bzip2. During testing I noticed that if I set the optimization level to O2 or greater, I'd get an unresolved symbol at link time.
It turns out that a function is declared in a header file and is used by two separate source files. In one of the source files, the function is defined with __inline__.
If I do function inlining during compilation (i.e. bitcode creation) I get the unresolved symbol because the function is discarded after it is inlined in the file that defines it. If I do function inlining during bitcode linking instead, everything works OK and the function is inlined everywhere it is used.
My question is, what should happen in this case? I don't mind deferring inlining until the link phase, but I have a feeling that that isn't correct behavior. Should a diagnostic be issued in this case?
