[petrochenkov]

Probably #44841, because the tests passed yesterday.
Observed on x86_64-pc-windows-gnu.

The issue with thin-lto-inlines2 disappears after disabling codegen-units in config.toml and doing a full rebuild (modulo LLVM) and reappears after enabling codegen-units in config.toml and doing a full rebuild.

[michaelwoerister]

Thanks for the bug report, @petrochenkov! Seems like a high priority issue.

[alexcrichton]

@petrochenkov it looks like the first test, specialization-cross-crate-defaults, may be failing due to paths > 255 characters?

[petrochenkov]

@alexcrichton
Ha! You are right, with help of that .rust-cgu suffix the object file path crossed the line of 255 characters.
The test passes if the name is shortened, I'll send a PR fixing this.

[alexcrichton]

Heh yeah we also need to do something about "specialization-cross-crate-defaults.stage2-x86_64-pc-windows-gnu.run-pass.libaux", that's a huge directory name!

[petrochenkov]

Fixed by #45215!
Closing.

[alexcrichton]

Thanks for checking! I meant to come back and test to see if this was fixed, but glad you beat me to it!
