<!-- There are issues with locking in function signatures with multiple possible
return locations. When the signature is committed/locked, Ghidra will apply the
first available location, which is incorrect. The decompiler can figure
out between two variable locations but doesn't currently pass back the
return storage location. A fix is needed, or use custom storage. -->
