Darwin's dynamic linker supports interposition and lazy symbol binding. If we are generating PIC code and a symbol is public, then it could potentially be indirected via a lazy-resolver stub; we cannot tell at compile-time if this will be done (since the indirection can be the result of adding a -flat-namespace option at link-time). Here we are conservative and assume that any such symbol cannot bind locally. The default implementation for binds_local_p handles undefined, weak and common symbols which are always indirected (for mdynamic-no-pic also). gcc/ChangeLog: PR target/100152 * config/darwin.c (darwin_binds_local_p): Assume that any public symbol might be interposed for PIC code. Update function header comment to reflect current Darwin capability.
