Test temporarily disabled here

dan-zheng commented 4 years ago

I wonder if these test failures are not caught by "@swift-ci Please test"?
Are they tested only by continuous CI, not by PR CI?

dan-zheng commented 4 years ago

I tried building with the same preset as the CI invocation (buildbot,tools=RA,stdlib=RD), but it failed:

My best guess is that this only happens with debug (unoptimized) standard library.

@shahmishal any advice for an external contributor trying to test the simulator-i386 configuration?

atrick commented 4 years ago

Could this be that you don't have Xcode 11.4 11E146?

Someone recently worked around this temporarily by editting ImageInspectionMachO.cpp and commenting out the call to __builtin_available()

aschwaighofer commented 4 years ago

When I ran into this issue in the past, I worked around this in the past by something like the following change.

I am actually using Xcode 11.4 (11E146).

Thanks aschwaighofer@apple.com (JIRA User)! I tried the workaround but now encounter a different error:

Have you seen this error before?
Unassigning self until I can build and reproduce the error locally.

atrick commented 4 years ago

Dumbest suggestion ever: make sure you do a clean build or at least 'build-script --reconfigure'

It seems that the Autodiff tests will be perpetually broken on 32-bit platforms if you're not locally testing that. That's just a headache for everyone. I recommend using REQUIRES: OS=..., REQUIRES: CPU=..., and/or REQUIRES: PTRSIZE=... if you don't want to support other platforms.

dan-zheng commented 4 years ago

Thanks for the suggestions!
I did indeed try clean builds. I'm using Xcode 11.4 (11E146) on macOS 10.15.4.
I would love to figure out these build errors so I can test 32-bit platforms locally. Any tips would be appreciated. I might post on the forums for help.
