Thanks! I think we need to be both more precise in the test expectations and in documenting them.
Can you make sure that the test
- expects precisely 2 (non-skeleton) DICompileUnits when the target is windows
- expects 0 DICompileUnit when the target is Darwin/linux/...
- documents why Windows is expected to have a DICompileUnit at -gnone ?

non-skeleton == no dwoId

I was able to implement such tests. I have updated the description of the PR. The check only tests for exactly 1 (non-skeleton) DICompileUnit when targeting Windows, not 2.

This patch splits up the
basic.swifttest into 3 files:basic.swiftfor macOS/linux basic testing: checking if we respect-gnoneor not.basic_windows.swiftfor windows basic testing: do we always emit basic debug information, even withgnone(Since [CodeGen][COFF] Always emit CodeView compiler info on Windows targets llvm/llvm-project#142970 we are always emitting minimal debug information on Windows. This brokeDebugInfo/basic.swift.)advanced.swiftfor all platforms, checking if we are emitting more advanced debug information correctly.basic.swiftandadvanced.swiftonly contain NFC changes, as this change only splits them into 2 files.
