Another R_X86_64_32S overflow check testcase:
[hjl@gnu-tools-1 pr19567]$ cat x.S
#ifndef SPACE
#define SPACE 0x80000000
#endif
.data
.space SPACE
.comm foo,4
.text
.globl _start
_start:
mov $foo,%rax
movl $1, (%rax)
movl $93, %eax /* Syscall number -> rax. */
syscall /* Do the system call. */
[hjl@gnu-tools-1 pr19567]$ make LD=ld
gcc -mx32 -c -o x.o x.S
ld -m elf32_x86_64 -o x x.o
x.o: In function `_start':
