The loader can usually handle an unaligned import dir chunk, but It's not optimal and it's not what MSVC link.exe does. Windows refuses to load ARM64X binaries with unaligned import directory. aarch64 and arm64ec imports are shared in such binaries as much as possible. As long as they use the same set of functions from given import directory, both the directory and import addresses chunk are just shared. When used set of functions differs, ARM64X dynamic relocations are used to modify import dir to point to different names and import addresses for its EC view. I suspect that the loader expects some alignment on ARM64X dynamic relocation offset and may not be the case when relocated import dir is not aligned.

Make a DLL that exports a few functions, then make a DLL with PDBs that imports
|
|
them. Check that the __imp_ pointer and the generated thunks appear in the

publics stream.
