ippStsFeaturesCombination
This warning means individual feature selectors may be known, but the set is inconsistent or unsupported as a combination for dispatch control.
It is relevant to tests and benchmark harnesses that force specific CPU paths. A feature set that cannot exist together on a real processor should not be used to select an optimized implementation.
Diagnostic focus
- Validate feature masks against the actual CPUID feature set.
- Avoid constructing combinations by OR-ing flags from different CPU generations without constraints.
- Prefer automatic dispatch unless a reproducible benchmark or diagnostic requires a forced path.
