hjyamauchi commented 4 days ago

This is a new compiler crash on Windows X64 in an internal app release build with the following error message:

Optimizer/BorrowUtils.swift:494: Fatal error: cannot get borrow introducers for unknown guaranteed value

Could this be related to SwiftCompilerSources? If so, is there a way to temporarily disable BorrowUtils (swift/SwiftCompilerSources/Sources/Optimizer/Utilities/BorrowUtils.swift)? I'm trying to see if disabling SwiftCompilerSources would fix this.

eeckstein commented 4 days ago

Yes, this error comes from SwiftCompilerSources. But it's probably not windows specific. Can you try to create a reproducer?

Anyway, please do not disable SwiftCompilerSources on Windows in general.

Will try.

Anyway, please do not disable SwiftCompilerSources on Windows in general.

Yes okay.

eeckstein commented 4 days ago

Can you compile the test program with -Xfrontend -sil-verify-all? This should give us the optimization pass which is causing the problem.

hjyamauchi commented 4 days ago

This is what I get with -Xfrontend -sil-verify-all passed to swiftc. I'm not sure if it output anything extra. But is it JumpThreadSimplifyCFG?

error: compile command failed due to exception 29 (use -v to see invocation)

Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the crash backtrace.

okay, thanks. You can try to workaround with -Xllvm -sil-disable-pass=jumpthread-simplify-cfg. Anyway, it would be great to have a reproducer.

hjyamauchi commented 3 days ago

Yeah. Will try that flag and look for a reproducer.

hjyamauchi commented 3 days ago

The workaround flag seems to work!
