--- Comment #10 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
With the fixed testcase we get:
movq %rsi, %rax
movq %rsi, %rcx
shrq $6, %rax
andl $63, %ecx
movq (%rdi,%rax,8), %rax
shrq %cl, %rax
andl $1, %eax
ICC can produce the btq but with extra instructions still:
movq %rsi, %rax #5.25
shrq $6, %rax #5.25
movq (%rdi,%rax,8), %rdx #5.13
xorl %eax, %eax #5.61
btq %rsi, %rdx #5.61
setc %al
