[llvm-dev] JIT tests on AArch64 (original) (raw)

Other general LLVM tests fail with 8.2.0.

Don't spend too much time chasing this down. I just wanted to see if anyone is aware of issues with gcc 6.1.0. Sounds like not. I will keep investigating on our end. It may be something with our environment is strange. If/when I figure something out I'll report it.

Hi David,

I don't have access to a gcc 6.1.0 / aarch64 setup, but I've tried the tests locally and they're passing asan/ubsan/tsan clean, and there is no obvious uninitialized memory use in the test case (though who knows where it might be inlined from in a release build).

When you say other tests broke with 8.2.0, do you mean other ORC tests specifically, or just other LLVM tests?

Cheers, Lang.

I am afraid nothing leaps to mind. Once you have a chance to look at them again please let me know -- I'd be happy to look at backtraces / failures. Huh. Now the problem has disappeared. A colleague updated to ToT and now I'm not seeing the failures, even with gcc 6.1.0 in Release mode.

User error. I was building on the wrong branch!

I am still seeing these errors with gcc 6.1.0 in Release mode.

Is there anything else useful I can provide to help track this down?

When I tried gcc 8.2.0 these tests passed but some others broke. :(
