Add -z noreloc-overflow command-line option to the x86-64 ELF linker to disable relocation overflow check. This can be used to avoid relocation overflow check if there will be no dynamic relocation overflow at run-time. bfd/ PR ld/19807 * elf64-x86-64.c (elf_x86_64_relocate_section): Check no_reloc_overflow_check to diable R_X86_64_32/R_X86_64_32S relocation overflow check. include/ PR ld/19807 * bfdlink.h (bfd_link_info): Add no_reloc_overflow_check. ld/ PR ld/19807 * Makefile.am (ELF_X86_DEPS): Add $(srcdir)/emulparams/reloc_overflow.sh. * Makefile.in: Regenerated. * NEWS: Mention -z noreloc-overflow. * ld.texinfo: Document -z noreloc-overflow. * emulparams/elf32_x86_64.sh: Source ${srcdir}/emulparams/reloc_overflow.sh. * emulparams/elf_x86_64.sh: Likewise. * emulparams/reloc_overflow.sh: New file. * testsuite/ld-x86-64/pr19807-1.s: New file. * testsuite/ld-x86-64/pr19807-1a.d: Likewise. * testsuite/ld-x86-64/pr19807-1b.d: Likewise. * testsuite/ld-x86-64/pr19807-2.s: Likewise. * testsuite/ld-x86-64/pr19807-2a.d: Likewise. * testsuite/ld-x86-64/pr19807-2b.d: Likewise. * testsuite/ld-x86-64/pr19807-2c.d: Likewise. * testsuite/ld-x86-64/pr19807-2d.d: Likewise. * testsuite/ld-x86-64/pr19807-2e.d: Likewise. * testsuite/ld-x86-64/x86-64.exp: Run PR ld/19807 tests.
