Bootstrapping (aka. `SwiftCompilerSources`) state on Windows #61410

Open stevapple opened 2 years ago

stevapple commented 2 years ago

Describe the bug Bootstrapping the Swift toolchain on Windows still fails at the time. We should look into this problem before more features rely on it and the process becomes mandatory.

Steps To Reproduce Steps to reproduce the behavior:

  1. Build the Swift toolchain with -DBOOTSTRAPPING_MODE=BOOTSTRAPPING. ...

Expected behavior Ideally the toolchain should be able to bootstrap. This was formerly blocked by some linker / runtime issue, but now new problems occurred during build steps, before the link step.

Environment (please fill out the following information)

Additional Context The issue is used to track the state of Swift bootstrapping ability on Windows.

This looks like a compiler bug regarding C++-Interop with MSVC, but it could also be related to module maps of used C++ modules.

finagolfin commented 2 years ago

Note that the mandatory bootstrapping will not use C++ Interop, only C Interop for the first year, so you may have more time to figure this out.
