The combination of -masm=intel and -fPIC when producing 32-bit causes strange
behaviour when dealing with globals. Bug is similar to Bug 12186(I'm
using ld version 2.21, tested Bug 46275 and it's successfully fixed).
But I'm linking another code.
typedef void (*pFuncAddress) (void);
pFuncAddress SomeFunc = (pFuncAddress)0x12345678 ;
void main(void)
{
__asm__ (".intel_syntax noprefix\n"
"call dispatch");
return;
}
void dispatch(void)
{
SomeFunc();
}
looking in objdump of output file:
0804809a <dispatch>:
804809a: 53 push %ebx
804809b: 83 ec 08 sub $0x8,%esp
804809e: e8 00 00 00 00 call 80480a3 <dispatch+0x9>
80480a3: 5b pop %ebx
80480a4: 81 c3 17 10 00 00 add $0x1017,%ebx
80480aa: 8b 83 fc ff ff ff mov -0x4(%ebx),%eax
80480b0: ff 10 call *(%eax)
80480b2: 58 pop %eax
80480b3: 5a pop %edx
80480b4: 5b pop %ebx
80480b5: c3 ret
0x80480a3 + 0x1017 = 80490BA, but
0x080490bc <_GLOBAL_OFFSET_TABLE_>:
