Bug #: 14088
Summary: Strange addend from readelf
Product: binutils
Version: 2.23 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: binutils
AssignedTo: address@hidden
ReportedBy: address@hidden
Classification: Unclassified
On Linux/x86-64, I got
address@hidden runtime]$ cat tst-quadmod2.S
#define BIAS -0x7fff0000
.section .data.rel.local,"aw",@progbits
.align 8
.Ljmp:
.quad func + BIAS
.text
.type func, @function
func:
.cfi_startproc
xorl %edi, %edi
jmp address@hidden
.cfi_endproc
.size func, .-func
.globl foo
.type foo, @function
foo:
.cfi_startproc
.cfi_def_cfa_register 6
movq .Ljmp(%rip), %rax
subq $BIAS, %rax
jmp *%rax
.cfi_endproc
.size foo, .-foo
address@hidden runtime]$ make libtst-quadmod2.so
gcc -B./ -c -g -o tst-quadmod2.o tst-quadmod2.S
./ld -shared -o libtst-quadmod2.so tst-quadmod2.o
address@hidden runtime]$ readelf -r libtst-quadmod2.so
Relocation section '.rela.dyn' at offset 0x1e8 contains 1 entries:
Offset Info Type Sym. Value Sym. Name +
Addend
0000002003f8 000000000008 R_X86_64_RELATIVE
ffffffff80010240
Relocation section '.rela.plt' at offset 0x200 contains 1 entries:
Offset Info Type Sym. Value Sym. Name +
Addend
0000002003f0 000600000007 R_X86_64_JUMP_SLO 0000000000000000 exit + 0
Addend for R_X86_64_RELATIVE is a negative number. But it is displayed
as an address.
