--- Comment #2 from Arseny Solokha <asolokha at gmx dot com> ---
It also can be reproduced for x86_64 when compiling the following testcase,
reduced from gcc/testsuite/gcc.target/i386/pr103144-mul-2.c, w/
-march=3Dsilvermont -O2 -fvect-cost-model=3Ddynamic:

void
foo_mul_peel (int *a, int b)
{
  int i;

  for (i =3D 0; i < 7; ++i)
    {
      b *=3D 2;
      a[i] =3D b;
    }
}=
