Consider reloadWeight while evaluating spill cost by kunalspathak · Pull Request #53853 · dotnet/runtime

kunalspathak · 2021-06-08T07:52:20Z

In SPILL_COST heuristics, we always check the spill cost of recentRefPosition (last ref position) where the register was allocated. Spill cost is essentially the ref count weight of a variable. However, later, we check if that recentRefPosition is not RegOptional and is actual ref. If it is not, we skip spill it at the recentRefPosition and would instead reload at the next refPosition. As such, when calculating the spill cost, we should take that factor into account and depending on if we we will spill at last location or reload at next location, take the cost of appropriate position.

Here is the sample diff:

Note below, that we spill a low weight variable on stack in favor of using register for higher weight variable.

Below are diffs of benchmarks/ libraries on following configuration:

Windows x64/arm64/x86
Linux x64/arm64/arm

I have collected 4 metrics to get a sense of this change:

CodeSize
PerfScore
Spill Count (no. of spills added)

While there are minor CodeSize regression, the perfScore benefis greatly, specially for windows x64, both on libraries and benchmarks. For certain configurations (e.g. Linux x64), the total PerfScore shows regression, but relative perf score has improvement which I take as improvement. For x86, the improvements are smaller and spills are little more because of register pressure, but overall libraries PerfScore still looks great. Even for benchmarks, the relative perf score shows improvement.
