In a large project I'm doing in my day job, it's been the first time a
more recent compiler version finally reduced the code size again
(after all the 3.x versions gradually increased the average code
size).  The saving wasn't overwhelming though, about 5 %, but given
that IAR used to be about 10 % better on average, we've at least
regained half of that. ;-)
