You might want to consider upgrading:
.file "nan.c"
.text
.section .rodata.str1.1,"aMS",@progbits,1
.LC0:
.string "yes"
.LC1:
.string "no!"
.LC3:
.string "what %s\n"
.section .text.startup,"ax",@progbits
.p2align 4,,15
.globl main
.type main, @function
main:
.LFB17:
.cfi_startproc
pxor %xmm0, %xmm0
subq $8, %rsp
.cfi_def_cfa_offset 16
movabsq $9218868437227405312, %rdx
divsd %xmm0, %xmm0
leaq .LC0(%rip), %rsi
leaq .LC3(%rip), %rdi
movq %xmm0, %rax
btrq $63, %rax
cmpq %rdx, %rax
leaq .LC1(%rip), %rax
cmovbe %rax, %rsi
xorl %eax, %eax
call printf@PLT
xorl %eax, %eax
addq $8, %rsp
.cfi_def_cfa_offset 8
ret
.cfi_endproc
.LFE17:
.size main, .-main
.ident "GCC: (Debian 8.2.0-14) 8.2.0"
.section .note.GNU-stack,"",@progbits
That sufficiently efficient for you?
Ciao,
Markus
