On x86-64, when -z nocopyreloc is used to build executable, relocations may overflow at run-time or may not be resolved without PIC. This patch checks these conditions and issues an error with suggestion for -fPIC. bfd/ PR ld/22001 * elf64-x86-64.c (elf_x86_64_relocate_section): Check for R_X86_64_PC32 relocation run-time overflow and unresolvable R_X86_64_32S relocation with -z nocopyreloc. ld/ PR ld/22001 * testsuite/ld-i386/i386.exp: Run -z nocopyreloc tests. * testsuite/ld-x86-64/x86-64.exp: Likewise. * ld/testsuite/ld-i386/pr22001-1a.c: New file. * ld/testsuite/ld-i386/pr22001-1b.c: Likewise. * ld/testsuite/ld-i386/pr22001-1c.S: Likewise. * ld/testsuite/ld-x86-64/pr22001-1a.c: Likewise. * ld/testsuite/ld-x86-64/pr22001-1a.err: Likewise. * ld/testsuite/ld-x86-64/pr22001-1b.c: Likewise. * ld/testsuite/ld-x86-64/pr22001-1b.err: Likewise. * ld/testsuite/ld-x86-64/pr22001-1c.c: Likewise.
