alt Hacker News> So another win for being able to read arm assembly.
Yes, though that weird stuff with dollars in it is not normal AArch64 assembly!
The article could have mentioned the "stack moves once" rule.

See the AT&T vs Intel syntax since you aren't familiar with assembly:
I've never heard of that rule (though tbh I'm not allocating > 64KB of stack when I'm in assembly) and it seems Google hasn't either. While I'm sure it makes sense, I don't think I've ever seen that be enforced. At least in C/C++. Maybe it makes more sense for these stack inspecting garbage collectors but I've also heard of ones that just scan the stack without unwinding anything. I did a test asking Google's AI to generate a complicated C function, put it in godbolt, and there's plenty of push push push push ..... Pop Pop Pop Pop going on
It is due to the Plan 9 Assembly dialect most likely, because it wasn't enough that we already have differences between AT&T and Intel.

Still, I find great that Go got back the 1990's tradition that compiled languages have an assembler as part of their tooling, regardless of the syntax.
