4.0.4 4.1.2 4.2.4 4.3.3 4.4.0
-O0: 1.64 1.58 1.91 1.86 2.20
-O1: 4.12 4.60 10.14 5.31 5.43
-O2: 6.10 6.60 13.34 8.40 8.57
-Os: 4.82 5.38 10.92 6.54 6.77
-O3: 6.10 9.80 18.12 12.81 13.42
my 4.2.4 build is with checking enabled. I do not have a
x86_64 build from the 3.3 or 3.4 series available.
At -O0 with 4.3 the DF framework likely adds compile-time, with 4.4 it is
the (partial) tuple transition and maybe SSA at -O0, maybe IRA. Comparing
optimized build-times is likely unfair as we add optimization capabilities.
