[ELF] Error if --strip-all and --emit-relocs are used together --strip-all suppresses the creation of in.symtab This can cause a null pointer dereference in OutputSection::finalize() // --emit-relocs => copyRelocs is true if (!config->copyRelocs || (type != SHT_RELA && type != SHT_REL)) return; ... link = in.symTab->getParent()->sectionIndex; // in.symTab is null Let's just disallow the combination. In some cases the combination can cause GNU linkers to fail: * ld.bfd: final link failed: invalid operation * gold: internal error in set_no_output_symtab_entry, at ../../gold/object.h:1814 Reviewed By: ruiu Differential Revision: https://reviews.llvm.org/D66704 git-svn-id: https://llvm.org/svn/llvm-project/lld/trunk@369878 91177308-0d34-0410-b5e6-96231b3b80d8
