When DT_RELR is enabled, to avoid random run-time crash with older glibc binaries without DT_RELR support, add a GLIBC_ABI_DT_RELR symbol version, which is provided by glibc with DT_RELR support, dependency on the shared C library if it provides a GLIBC_2.XX symbol version. bfd/ * elflink.c (elf_link_add_dt_relr_dependency): New function. (bfd_elf_size_dynamic_sections): Call elf_link_add_dt_relr_dependency if DT_RELR is enabled. ld/ * ld.texi: Mention GLIBC_ABI_DT_RELR in -z pack-relative-relocs entry. * testsuite/ld-elf/dt-relr-glibc-1.c: New file. * testsuite/ld-elf/dt-relr-glibc-1a.rd: Likewise. * testsuite/ld-elf/dt-relr-glibc-1b.rd: Likewise. * testsuite/ld-elf/dt-relr.exp: Likewise.
