Cameron here is an example with the issue:

// bin/opt -reassociate repro.ll -S
define float @test1(float %arg, float %arg1, float %arg2, float %arg3) {

  %tmp1 = fsub fast float %arg3, %arg2
  %tmp2 = fadd fast float %arg, -5.000000e+02
  %tmp3 = fsub fast float %tmp1, %tmp2
  %tmp4 = fmul fast float %tmp3, %tmp3
  %tmp5 = fneg fast float %arg
  %tmp6 = fdiv fast float %tmp5, %arg1
  %tmp7 = fadd fast float %tmp6, %tmp4
  ret float %tmp7

}
