I am just trying to compare apples with apples.
You can't. Assuming mainline is your apple, then I assure you the
dataflow branch is a completely different kind of fruit.
You just can't compare the two that way.
The only way to compare the two is by looking at the end result (code
size, compilation speed, benchmarks). It's not really possible to
compare how these results are obtained, because the compiler internals
are completely different. Only the end result is comparable
