But ldc looks so bad.
Any comments from ldc users or developers? Because I see this
in many other measurements as well.
This definitely does not match up with my experience.
Particularly if you see this in many measurements, there might
be something iffy with the way you test. Could you please post
a runnable snippet that demonstrates the issue?
No need to. Since you said it didn't match your experience I
checked. It turns out I was using last years ldc (0.15.2-beta2).
Version 0.16.0 behaves similar.
But for version 0.17.1 I get the following plots. ldc looks much
better. I make a note to check the fast math version once that's
release. But the code is integer heavy.

In general, could you please directly post any performance
issues to the LDC issue tracker on GitHub? We are quite
interested in them, but I only happened to come across this
post by chance.
Sorry about that. Next time.
