The code by "objdump --disassemble Schedule.thr_o" looks as follows:
00000284 <scheduleDoGC>:
284: 55 push %ebp
285: 57 push %edi
286: 56 push %esi
287: 53 push %ebx
288: 83 ec 1c sub $0x1c,%esp
28b: 89 c3 mov %eax,%ebx
28d: 89 44 24 08 mov %eax,0x8(%esp)
291: 89 d5 mov %edx,%ebp
293: 89 4c 24 04 mov %ecx,0x4(%esp)
297: 31 d2 xor %edx,%edx
299: b9 01 00 00 00 mov $0x1,%ecx
29e: 89 d0 mov %edx,%eax
2a0: f0 0f b1 0d 1c 00 00 lock cmpxchg %ecx,0x1c
