To be fair, RISC-V has a small base, RV64I in the 64-bit case. These bases are small, reduced and frozen. But after that, yes, the extensions get whacky. L is Decimal Floating Point, still marked Open. I'm not sure what's reduced

I've never liked this idea that x86 CPUs decode instructions into RISC form internally . Before there was RISC, before there was even x86, there were microcoded instruction sets [1]. They were first implemented in Wilkes' 1958 ED

Johnson had escalated the war, created it really, from the Gulf of Tonkin 'crisis'. By 1968, the war had failed and at some level everyone knew that. Johnson was not running for re-election and Nixon had a 'secret plan'

mov %rdx,%rcx Wouldn't this mov instruction be handled by the register renamer (Allocate/Rename/MoveElimination/ZeroIdiom) at essentially 'zero' cost? Yet clearly they're measuring a difference.

ePub. Definitely ePub (but really, why not both?). I have a million PDFs but for reading a book, ePub on either a Kindle or iPad is much more pleasant. I can read a PDF on the iPad or Kindle. But nothing beats reading something properly ren

This sounds like a more intelligent version of superoptimization. The original Masselin SO, albeit for its time, also created surprising results which is similar to AlphaDev's incomprehensible for humans . You see the same thing in co

Thanks for the correction. I did not know this. He even has some patents on dynamic linking. https://patents.justia.com/inventor/nick-kledzik

Apple calls their (now old) linker, ld64 , a static linker. On the other hand, dyld is their dynamic linker. This is wrong but Apple then is a $2.8T company. They should call ld64 their system linker or just their linker. They have

Did Lisp improve the IF statement? Certainly. But here's John freakin' McCarthy citing Fortran's IF statement which he had used. That means Lisp didn't invent the IF statement. Lisp invented better syntax. http:/

No, Lisp did not invent if statements. They're in Fortran's 1956 Programmer's Reference Manual. http://bitsavers.informatik.uni-stuttgart.de/pdf/ibm/704/704...

I'm a huge Obama fan but Afghanistan was his biggest mistake. In fairness, he got sold a bill of goods by the Pentagon and with the economy in a shambles, he was somewhat distracted. The Republicans greeted anything he did with stubb

One of the most disappointing things in American politics in the last ten to fifteen years has been watching the right cozy up to Putin.

Intel should gut as much cruft as possible, 16+32 bit support is cruft for anything with 64 bit, and also double the general purpose register set with another REX prefix trick. Indeed, AMD should have done this back in 1999.

The hit rate on that UOP cache is only about 80%, according to Intel. And UOP cache misses will have strong locality, so they can’t really be hidden.

If you’re going to road trip in an EV you have to plan out your charging in advance. Luckily there are apps for that, PlugShare in particular. You should have adapters so that your car can charge at RV parks. Charging will force you to stop

IR passes are meant to be easy to do . IR in, optimized or analyzed IR out. That is in fact the beauty of the LLVM architecture. Writing an effective general purpose pass, that is unbounded hard.

I think that is a relevant question because in related news, Intel didn't acknowledge MINIX. https://www.zdnet.com/article/minix-intels-hidden-in-chip-op...

The typewriter factory in Ivrea was ... a typewriter factory. Yeah, I worked on compilers but the building still built typewriters. I was there for a month before I was "allowed" to go to lunch by myself for fear of getting lost.
