What's the best way to analyze compiler performance on a per-file basis? I have couple of modules that take relatively long to compile, and I'm wondering if it's maybe some specific files that cause the issues. I'm almost certain I saw an answer to this already but couldn't find it. I tried using various flags like

-Xreport-perf

(with and without

kotlin.compiler.execution.strategy=in-process

) but I see no output anywhere, and I couldn't find any documentation outlining what flags exists and how they should work. I also tried

kotlin.build.report.output=file

but I don't think it provides the information I want (and it doesn't work anyway, always produces an empty file)
