2020-06-09PowerPC64: Downgrade ifunc with textrel error to a warningAlan Modra2-12/+13
For ppc64 I set flags when recording the dynamic relocation rather than when allocating space. That allows you to distinguish three cases: 1) The dynamic ifunc relocation is in an executable and will always be to an ifunc resolver in the executable. 2) The dynamic ifunc relocation is in a shared library which provides an ifunc resolver, but that may be overridden at runtime to use a resolver in another binary. 3) The dynamic ifunc relocation is not to a locally defined ifunc resolver. Case (3) won't cause a segfault trying to run resolver code that is non-exec on older glibc. I made case (1) an error for ppc64, but since newer glibc ld.so does allow running ifunc resolvers when segments are writable I suppose I should downgrade that to a warning like case (2). * elf64-ppc.c (struct ppc_link_hash_table): Delete maybe_local_ifunc_resolver field. (build_global_entry_stubs_and_plt): Set local_ifunc_resolver in cases where maybe_local_ifunc_resolver was set. (ppc64_elf_relocate_section): Likewise.

2020-06-03nios2: Don't check relocations in non-loaded, non-alloced sectionsH.J. Lu2-0/+15
Don't do anything special with non-loaded, non-alloced sections. In particular, any relocs in such sections should not affect GOT and PLT reference counting (ie. we don't allow them to create GOT or PLT entries), there's no possibility or desire to optimize TLS relocs, and there's not much point in propagating relocs to shared libs that the dynamic linker won't relocate. PR ld/26066 * elf32-nios2.c (nios2_elf32_check_relocs): Skip non-loaded, non-alloced sections.
