LLVM 14.0.0 AArch64 lldb failures #53697

Several lldb tests are failing on AArch64 when running the test-release.sh on Ubuntu bionic:

lldb-api :: functionalities/data-formatter/data-formatter-stl/generic/bitset/TestDataFormatterGenericBitset.py

lldb-api :: lang/cpp/std-function-step-into-callable/TestStdFunctionStepIntoCallable.py

The output for TestInferiorAssert.py looks something like this:

AssertionError: False is not True : Command 'disassemble -a 281474838502275
Error output:
error: Could not find function bounds for address 0xfffff7c31b83

Most of the others are something along these lines:

This issue was not resolved in time for 14.0.0 and will need to be fixed in the next release (14.0.1). If you disagree with this or you feel there was a mistake, please change the milestone back to 'LLVM 14.0.0 Release' so we can discuss.

rovka commented 2 years ago

As of 14.0.0-rc4, the only one of these failures left is lldb-api :: functionalities/inferior-assert/TestInferiorAssert.py. This might have something to do with the fact that we switched back to enabling libcxx in PROJECTS rather than RUNTIMES.

tstellar commented 2 years ago

@rovka Are these failures still present in 15.0.0-rc1 ?

rovka commented 2 years ago

@tstellar Yes, but @omjavaid says we can ignore them.
