Commen= t # 5 on bug 10374= 3 from Philip Rebohle 
I found another pair of equivalent expressions that produce di=
fferent results.

Working as expected:
    if ((floatBitsToUint(R0).y >=3D 0x4u ? 0xffffffffu : 0u) =3D=3D 0xff=
ffffffu)

Showing artifacts:
    if ((floatBitsToUint(R0).y >=3D 0x4u ? 0xffffffffu : 0u) !=3D 0u)
