CPU feature checking - require SSE3
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 SSE3 and refuses to install on unsupported hardware.
Streaming SIMD Extensions (SSE) is a single instruction, multiple data (SIMD) instruction set extension.
SSE3, also called PNI (Prescott New Instructions), is an incremental upgrade to SSE2, adding a handful of new operations useful for processing media. It is available on almost any 64-bit-capable processor except for some early AMD models (Sledgehammer and Clawhammer), but is not available on most 32-bit-only hardware.
