Lack of condition codes when the dominant paradigm (x86, ARM) is condition codes is weird. However, having 32 registers unlike x86_64's 16 makes up for some of it. The base is too base and their bitfield extension is weird.

Reagan was an entertainer for people who wanted entertainment. Carter was a decent man replaced by a vain man.

The title really should say RISC-V rather than RISC. MIPS already is a RISC, one of the first.

AMD pays substantial royalties to Intel for x86. https://jolt.law.harvard.edu/digest/intel-and-the-x86-archit... However, this will become moot as even Intel is shifting towards LLVM. https://www.intel.com&#

Intel is citing AMD as prior art. It isn't lazy. It's necessary background.

This thinking you're Google is the opposite of technical debt , avoiding doing something and then paying a recurring price for the expediency. This is paying a price up front by doing something which is then never used.

Apple released their iCloud Passwords extension [1] for Chrome last November. I actually moved away from Chrome to Safari when I migrated over to my new m1. It's actually pretty good. The one caveat is Google's Advanced Protecti

With respect to password managers, it doesn't mention Apple's iCloud Keychain. Any reason why?

I use VSC for C++. I use the clangd and VSCode NeoVim extensions. I don't use it as an IDE but as a code editor, it's the best I've had. Visual Studio and Visual Studio Code have nothing but two words in common. Dunno why

Even 64-bit systems today don’t address 64-bits of physical memory. The Arm A78 (a very random example) uses 40 bits of physical address space. The 128 bits would really be for arithmetic and bus widths.

Thanks, any comparison to Drepper is a distinction. I'd like a tool, maybe part of Cachegrind , which said dude, this instruction is thrashing this L2 set. A profiling virtual machine (Valgrind) is kind of the ultimate lookaside to do

I think the issues are the same for the arm64/m1. The cache structures are probably even similar. However, modern CPUs are out of order superscalar and dual ported. You might look at something like the Arm® Cortex®-A75 Software Optimiz
