#x86_64 — Public Fediverse posts

My assembler is getting x64 and ARM64 smarts. This is the first time it assembles simple arithmetic, writes an ELF64 binary, and then signs off correctly with the right exit code on linux/amd64.

go-simd-softmax

Is a Go-oriented SIMD/avx softmax implementation with optimisations in amd64 / x64 assembler.

Up to 3.5x faster than equivalent function written using stdlib only. See benchmarks.

I did a write-up on the information I could find on Intel's defunct 64bit extensions:

If you are interested in obscure ISA extensions that never shipped, that article is for you!

Anyone knows details about Intel's own pre-AMD64 64bit extensions for x86?

Details on the internet are rather sparse:

Specifically, I wonder which instruction encoding they picked (vs. AMD repurposing inc/dec instructions for REX).

Sobre a limitação em relação aos jogos e aplicativos no Waydroid: ela está ligada à arquitetura da CPU. Nosso computador utiliza um processador x86_64 (64 bits) e, como o Waydroid não é um emulador, ele é reconhecido como um tablet...
