With gcc 4.7.2:
call udhcp_sp_fd_set #
cmpl $0, bb_common_bufsiz1+52(%rip) #, MEM[(struct
server_config_t * {ref-all})&bb_common_bufsiz1].auto_time
movl %eax, %ebx #, max_sock
je .L71 #,
call monotonic_sec #
movl 24(%rsp), %edx # %sfp,
movq $0, 56(%rsp) #, tv.tv_usec
subl %eax, %edx # D.8343,
movl %edx, %eax #,
movq %rax, 48(%rsp) #, tv.tv_sec
.L71:
xorl %r8d, %r8d # iftmp.11
cmpl $0, bb_common_bufsiz1+52(%rip) #, MEM[(struct
server_config_t * {ref-all})&bb_common_bufsiz1].auto_time
je .L72 #,
cmpq $0, 48(%rsp) #, tv.tv_sec
jg .L110 #,
jmp .L166 #
.L110:
