Paketti: isa-support (26)

CPU feature checking - common back-end

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 package provides the feature-probing infrastructure. To assert a CPU requirement, other packages can pre-depend on one of the individual feature-specific packages:

sse2-support, sse3-support, sse4.2-support, altivec-support, neon-support, armv6-support, armv7-support, armv8-support, vfp-support, vfpv2-support, vfpv3-support
