We can't use the PLT entry as the function address for PIC since the PIC register may not be set up properly for indirect call. bfd/ PR ld/27998 * elf32-i386.c (elf_i386_relocate_section): Don't allow GOTOFF relocation against IFUNC symbol for PIC. ld/ PR ld/27998 * testsuite/ld-i386/pr27998a.d: Replace -shared with -e bar. * testsuite/ld-i386/pr27998b.d: Expect a linker error. * testsuite/ld-ifunc/ifunc-2-i386-now.d: Updated. * testsuite/ld-ifunc/ifunc-2-local-i386-now.d: Likewise. * testsuite/ld-ifunc/ifunc-2-i386.s: Replace @GOTOFF with @GOT. * testsuite/ld-ifunc/ifunc-2-local-i386.s: Likewise.
