For ld: 08050f40 <_Z4foobv>: 8050f40: 53 push %ebx 8050f41: 65 8b 1d 00 00 00 00 mov %gs:0x0,%ebx 8050f48: 81 c3 d0 ff ff ff add $0xffffffd0,%ebx 8050f4e: 5b pop %ebx 8050f4f: c3 ret Completely identical between ld and gld, except for the exact address of _Z4foobv itself due to different segment layout: For gld: 080488a0 <_Z4foobv>: 80488a0: 53 push %ebx 80488a1: 65 8b 1d 00 00 00 00 mov %gs:0x0,%ebx 80488a8: 81 c3 d0 ff ff ff add $0xffffffd0,%ebx 80488ae: 5b pop %ebx 80488af: c3 ret
