--- Comment #3 from Uroš Bizjak <ubizjak at gmail dot com> ---
The denormal in f5.0_16 is directly loaded from
f5.0_16 = .omp_data_i_14(D)->f5.0;
_17 = .omp_data_i_14(D)->is_f5;
_18 = *_17;
_43 = e5.1_15 != 8;
if (_18 < _43)
goto <bb 3>;
else
goto <bb 13>;
<bb 3>:
...
<bb 13>:
_40 = f5.0_16 != 6.5e+0;
l_36 = _40 & _18;
goto <bb 3>;
That corresponds to:
...
movss 8(%rdi), %xmm0
movl (%rax), %eax
cmpl $8, %ebp
setne %dl
cmpl %edx, %eax
jae .L2
movl $1, %r12d
.L13:
...
.L2:
xorl %edx, %edx
movl $1, %r12d
ucomiss .LC1(%rip), %xmm0
setp %dl
cmove %edx, %r12d
andl %eax, %r12d
jmp .L13
