Yes and no. The (very simplified) answer is that yes, some ISA (front-end) instructions are decoded into simpler back-end operations, but the design of the ISA still imposes constraints on the implementation of that decoder [1] and on the

You're right – fixed. That's what I get from writing code in a simple text area.

Both are rather ugly. This is much more idiomatic: match (x, y) { (Some(x), Some(y)) => Some(x + y), _ => None, }

An 8x8 bit multiplication only requires 7 additions, either in parallel or sequentially. Remember long-form multiplication? [1] It's the same principle. Of course, high-speed digital multiplication circuits use a much more optimized, m

Only for reasonably small stacks. Insertions at random indices won't stay O(1) when you're dealing with 100k pages and more – i.e., when you can't pick them up in one movement.

Can a train pick me up directly at my home, and drop me off at pretty much any destination, with more luggage than I can carry at once, at any time of the day, at the exact moment I want to leave? No? Then trains are an alternative to sel

I always wonder: If the proc macros were executed JIT-like with the Cranelift backend instead of compiling them with the LLVM backend, wouldn't that drastically reduce build times of proc-macro-using code? The Rust compiler spends most

It's only one part of your argument, but: > Waterfalls? With what gravity? Mars has gravity, and any serious space habitat would have a rotating section to simulate gravity.

So now you're arguing that Rust won't help because it doesn't fix the deficiencies of other languages? So what? At least you'll have fewer defects in those parts that do use Rust.

Not sure if you're serious, or if this is some attempt at satire? If it's the former: Okay, it's great that you don't feel the temptation to spy on your users, but even the most basic understanding of human nature should

I suspect it's sarcasm: > PayPal had an automatic github-algorithm [...] before they managed to coup him as CEO Musk stepped down as CEO of PayPal in 2000, predating not just Github, but git itself by 5 years.

To explain: The rcr instruction performs a right rotation and shifts the CF (carry flag) bit into the most significant position. Together with the preceding add instruction, this effectively provides an n+1 bit operation on n-bit regist

That doesn't work when both are odd. For example, for x=1 and y=3 this gives 1 instead of 2.
