This is by design, to lift the CPU and allocation costs to the foreground. You can argue that was a bad design decision, but it wasn't an oversight, as you imply in the OP.

So the AOT makes that more difficult I'm guessing? I think that go does heavy lto so shouldn't inlining at link time give the same opportunity for that?

Java's escape analysis has always been dodgy to rely on. I've had some very simple code when I couldn't for the life of me figure out why the allocations weren't being hoisted. So I don't know if gos is better or worse.

It most definitely was not an oversight, clearly intentional but I think the issues could have been solved in better ways. Better use of lto and intrinsifying some functions in slices would help a lot.

Vector operations are extremely common. Go's making them difficult to use and refusing to optimize them (lto, intrinsics, etc) just seems poor.

PS: because of the score of my top level comment I've been rate limited pretty aggressively and can't respond anymore.

I’m pretty sure Go does not do any LTO at all.
