Description
Compiler version
3.2.1-RC1-bin-20220829-63344e7-NIGHTLY
Minimized code
I do not have one yet. I experience the issue in a close source project, a few thousands of lines of code.
Output
compiling 388 Scala sources and 5 Java sources to C:\Dev\tempi\target\scala-3.2.1-RC1-bin-20220829-63344e7-NIGHTLY\classes ...
Total time: 705 s (11:45), completed 1. 9. 2022 15:00:43
The project takes very long to compile (~10 minutes).
Expectation
The same project compiles about 30 seconds
Notes
I have attached VisualVM to the process and performed CPU sampling. I have seen a lot of time (almost all) in following functions:
dotty.tools.dotc.util.SimpleIdentityMap$MapMore.apply ()
dotty.tools.dotc.core.OrderingConstraint$$anon$1.entries()
dotty.tools.dotc.core.OrderingConstraint$anon$3.entries()
