sse4.1-support - 26 main

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 SSE4.1 and
refuses to install on unsupported hardware.
.
Streaming SIMD Extensions (SSE) is a single instruction, multiple data
(SIMD) instruction set extension.
.
SSE4.1 added a dot product instruction and additional integer instructions.
It is available on Intel processors since Penryn (circa 2008), but notably
not on anything AMD until the Bulldozer (15h, in 2011) and Jaguar (16h, in
