CPU feature checking - require altivec
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 altivec and refuses to install on unsupported hardware.
AltiVec is a single-precision floating point and integer SIMD instruction set. It is a standard part of the Power ISA v.2.03 specification.
