Clang 19 has become more strict about initialization with undefined
behavior, resulting in errors similar to:
./SimpleModule.h:126:40: error: in-class initializer for static data member is not a constant expression
126 | static const int kMinSignedValue = -1 << kScaleBits;
| ~~~^~~~~~~~~~~~~
./SimpleModule.h:176:22: note: in instantiation of template class 'signConverter<kInt8>' requested here
176 | transform<typename signConverter<Format>::signedToUnsigned>(src, dst, count);
| ^
./SimpleModule.h:183:5: note: in instantiation of function template specialization 'ConvertSign::convertSignedToUnsigned<kInt8>' requested here
183 | convertSignedToUnsigned<kInt8>(src, dst, count);
| ^
This is because left-shifting negative values is undefined. Replace -1
with ~0u which results in the expected value.
While here, add a few other patches to remove warnings about undefined
left-shifts, and add support for the "make test" target.
