Good question!
I've modified the example with floating-point values and accessed
records (nearer to the "real" example) : impossible to fool that
diabolical GNAT optimizer. I'll try to refind my test sources.
Another nice thing that GNAT does is to re-use the address
computation for 2 arrays in 2 different instructions (not too near)!
