This somehow reminds me on this old anecdote:
A novice was trying to fix a broken Lisp machine by turning the power
off and on.
Knight, seeing what the student was doing, spoke sternly: “You cannot
fix a machine by just power-cycling it with no understanding of what is
Knight turned the machine off and on.
The machine worked.
For whatever reason, now that I know what to look for, I see that
branchweights are emitted. And for some reason, it works now as expected
(though I like to blame Xcodes deficient Assembly preview, for some of
my confusion :))
Thanks for the help
