            Bug ID: 19939
           Summary: Incorrect error message for undefined symbols
           Product: binutils
           Version: 2.27 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: hjl.tools at gmail dot com
  Target Milestone: ---

address@hidden xxx]$ cat x.S
        .text
selector:
#ifdef __x86_64__
        movq    address@hidden(%rip), %rax
#else
        movl    address@hidden(%eax), %eax
#endif
        jmp     xxx
        .type   selector, %gnu_indirect_function
        .globl  bar
bar:
        jmp     address@hidden
address@hidden xxx]$ make LD=ld
gcc -B./  -c -o x.o x.S
ld -shared -z defs -o x.so x.o
ld: read-only segment has dynamic IFUNC relocations; recompile with -fPIC
ld: failed to set dynamic section sizes: Bad value
Makefile:24: recipe for target 'x.so' failed
make: *** [x.so] Error 1
address@hidden xxx]$ 

The dynamic reloc in read-only section is against normal symbol, xxx,
not IFUNC symbol, selector.
