A number of test cases were failing on big-endian systems simply due to
byte order assumptions in the tests themselves, and no underlying bug
in LLDB.
These two test cases:
tools/lldb-server/lldbgdbserverutils.py
python_api/process/TestProcessAPI.py
actually check for big-endian target byte order, but contain Python errors
in the corresponding code paths.
This test case:
python_api/sbdata/TestSBData.py (first change)
could be fixed to check for big-endian target byte order.
These test case:
python_api/sbdata/TestSBData.py (second change)
functionalities/memory/cache/TestMemoryCache.py
simply accessed memory with the wrong size, which wasn't noticed on LE
but fails on BE.
These test cases:
functionalities/data-formatter/data-formatter-python-synth/TestDataFormatterPythonSynth.py
functionalities/data-formatter/data-formatter-smart-array/TestDataFormatterSmartArray.py
functionalities/data-formatter/synthcapping/TestSyntheticCapping.py
lang/cpp/frame-var-anon-unions/TestFrameVariableAnonymousUnions.py
make byte order assumption, but since they're not using the Python API, I didn't
see an easy way to check for target byte order. Instead, I've changes those
test
to simply accept either the results see on a little-endian system or those seen
on a big-endian system.
