In this case, many of the divergences exist because the standard AArch64 ABI (AAPCS) wasn't finalized at the time that iOS had to lock its ABI. Several items are actually the standard version from pre-finalization versions of AAPCS, an

No, they started designing them earlier. A11 was the first one that they publicly claimed to be fully in-house. They were substantially (but not wholly) Apple-designed as early as A8, and generations prior to that they did significant tweak

The library owns a certain number of licenses to the audiobook, and only allows as many simultaneous check out as they have licenses. If none are currently available, you wait until one is returned. Just like a physical book.

In EU4 you control a country. In CK3 you control a dynasty, one ruler at a time. EU4 plays like a complex but fairly “normal” strategy game in a pseudo historical setting. CK3 is more focused on managing your complex web of feudal relations

ARM produces both architecture specifications and the designs for chips that implement those specifications. Some companies license the architecture specification and design their own implementations, Apple being the leading example. They t

LLVM makes use of assertions to validate things like this, but many users of LLVM, including rustc, turn them off for performance reasons.

GPUs ship with far more workarounds in the drivers because the programmer only has access to the hardware via drivers that can cover up the bugs, and because they’re not constrained by binary compatibility.

A particularly interesting note is that Asterix and Obelix actually gets different English translations for the US and UK markets, and they frequently rework the puns differently, presumably due to idiomatic differences.

ARM64 has cbz/tbz compare-and-branch instructions that cover many common cases in a single 4-byte instruction as well.

> This is in stark contrast with ARMv7's thumb, which was a literal separate CPU mode. This is disingenuous. arm32's Thumb-2 (which has been around since 2003) supports both 16-bit and 32-bit instructions in a single mode, maki

As someone who is an expert on ISA and CPU internals, this meme of "X86 has an internal RISC" is an over-simplification that obscures reality. Yes, it decodes instructions into micro-ops. No, micro-ops are not "quite close

To everyone who's saying "But macro-fusion!" in response, see my comment here: https://news.ycombinator.com/item?id=29421107

The argument for RISC instructions (in high performance architectures) is that the faster decode makes up for the increase in instruction count. The problem is that a faster decode has a practical ceiling on how much faster it's going

> I don't think they even tried to read the ISA spec documents. If they did, they would have found that the rationale for most of these decisions is solid: Evidence was considered, all the factors were weighted, and decisions were m

This isn't an isolated case. RISC-V makes the same basic tradeoff (simplicity above all else) across the board. You can see this in the (lack of) addressing modes, compare-and-branch, etc. Where this really bites you is in workloads do

Compressed instructions and macro-fusion aren't magical solutions. It's not always possible to convince the compiler to generate the magical sequence required, and it actually makes high-performance implementations (wide superscal

This technique is commonly used for smaller marine salvage operations. They're called "salvage tubes".

For smaller salvage operations, salvage tubes (basically balloons) are often used to raise the ship off the bottom. I suspect it's impractical due to the immense mass of this ship, but part of me wonders how large of a balloon you&#x27

In my experience it's very normal. Every employment application I've ever completed, spanning a couple of decades, has had two optional questions that were phrased in exactly this way.
