> We evaluated the Machine Function Splitter pass on clang bootstrap and SPECInt 2017.

Could you share the details of the machine as well? The improvements are well within noise.

> For clang bootstrap we observe a mean 2.33% runtime improvement with a
> ~32% reduction in itlb and stlb misses

While itlb reduction looks quite impressive, it doesn't seem to translate quite well to the runtime improvement. Did we see consistent >2% improvement with multiple runs? Please share then numbers.
