I'm only qualified to comment having been around for a long time and worked in multiple languages... (By way of saying I'm ignorant of this compiler and of PPC processor architecture!)
But elsewhere, a complex expression like that might entail converting its terms to floating point for the calculation and back again if the assignment were to an integer. This would make it much slower than purely integer computation. Could this be implicated in this case?
