PR26655, Power10 libstdc++.so R_PPC64_NONE dynamic relocs
Some of the powerpc64 code editing functions are better run after dynamic symbols have stabilised in order to make proper decisions based on SYMBOL_REFERENCES_LOCAL. The dynamic symbols are processed early in bfd_elf_size_dynamic_sections, before the backend always_size_sections function is called. One function, ppc64_elf_tls_setup must run before bfd_elf_size_dynamic_sections because it changes dynamic symbols. ppc64_elf_edit_opd and ppc64_elf_inline_plt can run early or late, I think. ppc64_elf_tls_optimize and ppc64_elf_edit_toc are better run later. So this patch arranges to call some edit functions later via always_size_sections. PR 26655 bfd/ * elf64-ppc.c (ppc64_elf_func_desc_adjust): Rename to.. (ppc64_elf_edit): Call params->edit. (ppc64_elf_tls_setup): Don't call _bfd_elf_tls_setup. Return a bfd_boolean. * elf64-ppc.h (struct ppc64_elf_params): Add "edit". (ppc64_elf_tls_setup): Update declaration. ld/ * emultempl/ppc64elf.em (params): Add ppc_edit. (ppc_before_allocation): Split off some edit functions to.. (ppc_edit): ..this, new function.
