sse4.2-support binary package in Ubuntu Oracular amd64
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 SSE4.2 and
refuses to install on unsupported hardware.
.
SSE4.2 added string and text processing instructions that perform character
searches and comparison on two operands of 16 bytes at a time. It is
available on Intel processors since Nehalem (circa 2008), but notably not
on anything AMD until the Bulldozer (15h, in 2011) and Jaguar (16h, in
2013) families.
