------- Comment #4 from pinskia at gcc dot gnu dot org 2006-03-05 17:43 -------
In 4.2.0 and above we get:
baz:
.LFB2:
mulsd %xmm1, %xmm0
mulsd %xmm0, %xmm0
mulsd %xmm0, %xmm0
ret
Which is what I recommend but we don't get that on the tree level:
return bar * bar * __builtin_pow (foo, 4.0e+0) * bar * bar;
So this is just a tree level missed optimization.
