Is there a reason that the inner save and restore must be separate? Why couldn’t peephole optimization remove them?

I had hoped that this article wouldn’t require x86 assembly fluency to read; it really is a “port” of my prior article on x86-64 assembly. I wrote it because mobile developers, at least, probably care more about ARM64 than x86-64. Is there

I’d be happy to port the article to ARM64 if there was sufficient demand for that, but I think it’s still fairly niche among developers, right? (Apple, recent Android, niche server environments?) Are you talking about ARM64 or ARMv7?

Thanks! Fix should deploy momentarily. This is what I get for duplicating the examples across Godbolt and the post itself. It was originally 3D for no particular reason and I cut it to keep things short.

The condition is known as "brain fog". For example: https://www.healthline.com/health/brain-fog#causes I've also seen common cold listed as a potential cause, which definitely jibes with my experience.

2^109 nanoseconds is still 150,000 times older than the universe. If you do manage to get a trillion computers, you can now solve the problem in twenty thousand years. It's still intractable.

I think of this attitude as being a stereotype of mathematicians. "I've already proved that a solution must exist; finding it is just drudgery." Perhaps the author would enjoy branching into one of the more theoretical branch

PICO-8 limits the textual size of your input Lua file, so I'd imagine that it might be possible to squeeze more content into your game with a small interpreter and packed binary format represented as a printable string.

Why do you claim that local variables and function calls are specific to C? They seem to be very popular among programming languages in general.
