Nem tudom mi lesz az AVX-512 jövője az AMD oldalon ..
de mivel illeszteni kell az Intelhez is ( APX & AVX10 )
változások várhatóak ..
"according to this gcc patch,
#AVX512_VP2INTERSECT is deprecated in AMD Zen6"

ami - ahogy látom az Intel hatása ...
2022 Okt.13: az Intel 46th ISA Ext guide:
RIP #AVX512_VP2INTERSECT (2x3 insts altogether),
https://twitter.com/InstLatX64/status/1580461486224252929
úgyhogy az AVX512_VP2INTERSECT - csak a zen5-ben lesz.

érdekesség:
ISA ügyben mi várható .. az LLVM 18 - alapján ..
https://www.phoronix.com/news/LLVM-Clang-18.1-Released
- ISA support for Intel AVX10.1-256 and AVX10.1-512.
- Intel Panther Lake and Clearwater Forest targets are now added with -march=pantherlake and -march=clearwaterforest.
- The "-mapxf" switch is now supported as part of the ongoing Intel Advanced Performance Extensions (APX) enablement.
- Alpha support for ARM SVE2.1 intrinsics.
- Various new RISC-V instructions are supported. The SiFive P670 target is also now supported.
- Support for Arm Cortex A520, A720, and X4 CPUs. The Arm Cortex-M52 CPU is also now supported.
- LLVM 18 on LoongArch now supports LSX 128-bit and LASX 256-bit SIMD with new intrinsics. LoongArch on LLVM also has initial support for auto vectorization and linker relaxation.

Mottó: "A verseny jó!"
