Research direction

Start with the linked benchmark sources: src/benchmarks/micro/runtime/Math/Functions/Single/Min.cs, SinPi.cs, Double/Min.cs, and BilinearInterpol/BilinearInterpol.cs. Run the listed benchmarks_ci.py commands and compare the referenced reports against the baseline and compare commits. The issue does not specify a fix or acceptance criterion, so the completed outcome is not defined.
