...al linker symbols. I propose two things. 1. Provide a hook as per what Shankar suggested for the resolver. User references to linker defined symbols such as _GLOBAL_OFFSET_TABLE_ get created and possibly deadstripped here. The linking context owns the atom. 2. The ELFLinkingContext gains <Atom *getOrCreateLinkerDefinedAtom(StringRef);>. This can be used in passes to get the symbols. The hook in (1) would call this to create the atoms. This gives a single place where linker defined atoms are actually created, and allows correct deadstripping and object file references without doing multiple resolver passes. - Mic...
