We have
bash-3.1$ cat foo.s
SEGMENT_SIZE = 0x10000
RVECTOR = 0x00010
.code16
.globl _start
_start:
#jmp 0xfef0
jmp SEGMENT_SIZE-(0x1f00 +0xf0 +RVECTOR)
bash-3.1$ gcc -c -m32 foo.s
bash-3.1$ ./objdump -Mi8086 -dr foo.o
foo.o: file format elf32-i386
Disassembly of section .text:
00000000 <_start>:
0: e9 fe df jmp ffffe001 <SEGMENT_SIZE+0xfffee001>
1: R_386_PC16 *ABS*
That is a relocation against ABS section. But many ELF linkers have
if (r_symndx == 0)
{
/* r_symndx will be zero only for relocs against symbols from
removed linkonce sections, or sections discarded by a linker
script. For these relocs, we just want the section contents
zeroed. Avoid any special processing. */
_bfd_clear_contents (howto, input_bfd, contents + rel->r_offset);
continue;
}
The above comment and code are certainly incorrect for this testcase.
