CMake build fails on macOS Sequoia with Xcode 16 release version #76631

Open ADKaster opened 1 month ago

ADKaster commented 1 month ago

Description

Cloning the repo with Xcode 16 selected and CMake 3.30.3 fails to build using the following steps:

cmake -B build -GNinja
ninja -C build

Xcode Version 16.0 (16A242d)

swift-driver version: 1.115 Apple Swift version 6.0 (swiftlang-6.0.0.9.10 clang-1600.0.26.2) Target: arm64-apple-macosx15.0

cmake version 3.30.3

ninja version: 1.12.1

The build fails in the same way on both:

main: 47b127f1c98a9f4ff593288c7ee0c6618a912e6b release/6.0.2: 3755346b1da0f611d3a8bd531831ac48c126b9d4

Expected behavior

Same build as swift build is produced

Actual behavior

Backtrace in the linked gist below

https://gist.github.com/ADKaster/8c62194d219a6f6599c2409d24e304e4

It appears to be a problem with swift-syntax?

1.  Apple Swift version 6.0 (swiftlang-6.0.0.9.10 clang-1600.0.26.2)
2.  Compiling with effective version 5.10
3.  While evaluating request ExecuteSILPipelineRequest(Run pipelines { Non-Diagnostic Mandatory Optimizations, Serialization, Rest of Onone } on SIL for TestingMacros)
4.  While running pass swiftlang/swift-testing#396 SILFunctionTransform "OwnershipModelEliminator" on SILFunction "@$s11SwiftSyntax9TokenKindO2eeoiySbAC_ACtFZ".
 for '==(_:_:)' (in module 'SwiftSyntax')

Steps to reproduce

git clone cd swift-testing cmake -B build -GNinja cmake --build build

Also fails with Xcode 16.1 Beta 2

Do you get a different result if you first revert the change in swiftlang/swift-testing#690?

grynspan commented 1 month ago

What's your thinking Stuart?

ADKaster commented 1 month ago

@stmontgomery Yes, applying this diff on top of 47b127f1c98a9f4ff593288c7ee0c6618a912e6b allows the build to complete

grynspan commented 1 month ago

Sounds like a compiler bug that's conflicting with the 600.0.0 tag. We aren't seeing the compiler issue with the latest main-branch toolchain (our CI is happy.) We should send this over to the Swift repo for triage, I think.

ChaseKnowlden commented 1 month ago

Failed to build for me as well.

ADKaster commented 1 month ago

I did see some interesting compiler warnings (visible in my gist in the initial post) about experimental features not being enabled as expected, so it could be some CMake flag trickery with the swift-testing repo and the imported swift-syntax target is causing conflicts that cause an unsupported configuration to be built.

stmontgomery commented 1 month ago

Thanks for those data points @ADKaster! Over to the swift repo to investigate the build failure further.

CC @ahoppen @bnbarham for visibility

That's interesting to note. Here are those warnings pulled out for convenience:

This should resolve the issue: https://github.com/swiftlang/swift-syntax/pull/2872 But swift-testing would need to update the reference here https://github.com/swiftlang/swift-testing/blob/83b0b049d6f73b58e05c0e3f1864c9b1db8b07b0/Sources/TestingMacros/CMakeLists.txt#L34

Thanks @rintaro ! I'll be happy to update that, once your fix lands in a new tag of swift-syntax.

and AFAICT SWIFTSYNTAX_EMIT_MODULE is staying for toolchain builds so there's still some underlying issue.

rintaro commented 3 weeks ago

@Bo98 would you let know know your environment ?

Bo98 commented 3 weeks ago
  • What the exact version of Xcode/toolchain are you using for building the toolchain?

Swift 6.0 (swiftlang-6.0.0.9.10 clang-1600.0.26.2), from Xcode 16.0

What branch/commit of swift repo?

swift-6.0.1-RELEASE

  • What command line build-script invocation?

I've slimmed it down a bit to:

utils/build-script \
--release \
--skip-build-benchmarks \
--swift-include-tests=0 \
--llvm-include-tests=0 \
--build-swift-private-stdlib=0 \
--swift-darwin-supported-archs="$(uname -m)" \
--install-destdir=/tmp/swifttest \
--install-swift \
--install-llvm \
--swift-testing-macros
rintaro commented 3 weeks ago

@Bo98 thank you for the info!

The crash happens when

Building swift-6.0.1-RELEASE with Swift 6.0 in Xcode 16.0 meets these conditions. So the failure is expected unfortunately.

In short, package CMO enabled serialized .swiftmodule are not usable from outside the package. And yes, we should consider it'a compiler bug. The compiler should fallback to the resilient .swiftinterface in such cases.

Bo98 commented 1 week ago

Would I be correct in assuming this is tracked as rdar://134584629 (as indicated from #76338)?

rintaro commented 1 week ago

Apparently we have made .swiftmodule usable from outside. https://github.com/swiftlang/swift/pull/76729 cc: @elsh

Bo98 commented 1 week ago

Good spot! Cherry-picking that onto 6.0.1 does indeed fix the build.
