Paketti: x86-64-v3-support (24)

CPU feature checking - require x86-64-v3

The packages in the isa-support family probe for microprocessor Instruction Set Architecture features such as SSE3. By refusing to install on machines lacking a required feature, they allow ISA requirements to be handled in terms of package dependencies.

This is a mostly dummy package which checks for x86-64-v3 and refuses to install on unsupported hardware.

This is the Micro-Architecture Levels version 3 as defined by the amd64 ABI document. This includes: - cmov instruction (CMOV instruction set), - cmpxchg8b ant other 64 bits atomics instruction (CX8 instruction set), - MMX a single instruction, multiple data (SIMD) instruction set, - streaming SIMD Extensions (SSE) set, a single instruction, multiple data

  (SIMD) instruction set extension,

- SSE2 an incremental upgrade to SSE. - cmpxchg16b ant other 128 bits atomics instruction (CX16 instruction set), - SSE3, also called PNI (Prescott New Instructions), is an incremental upgrade

  to SSE2,

- SSE4.1 added a dot product instruction and additional integer instructions, - SSE4.2 added string and text processing instructions that perform character

  searches and comparison on two operands of 16 bytes at a time,

- SSSE3 or Supplemental Streaming SIMD Extension 3, - Advanced Vector Extensions (AVX and AVX2) - Bit manipulation instructions sets (BMI and BMI2), - F16C instruction set converting between half-precision

  and standard IEEE single-precision floating-point formats,

- LZCNT instruction, Count the Number of Leading Zero Bits, - OSXSAVE, Save Processor Extended States instruction.

The corresponding micro-architecture level from the x86-64 psABI. On ABIs other than the x86-64 psABI they select the same CPU features as the x86-64 psABI documents for the particular micro-architecture level.
