In keeping with your choice of "target" category, I think this is a
Darwin-specific thing. ASM_DECLARE_OBJECT_NAME() in config/darwin.h says:
/* Darwin doesn't support zero-size objects, so give them a \
byte. */ \
if (tree_low_cst (DECL_SIZE_UNIT (DECL), 1) == 0) \
assemble_zeros (1); \
Adding extra data behind varasm's back is going to play havoc with
any attempt to place objects correctly.
I'm considering adding equivalent code to varasm.c. This will fix
an inconsistency in the handling of zero-sized decls: sometimes
they get a byte of storage allocated to them (giving them a unique
address) and sometimes they don't.
If the patch works out, I'll remove the code above. Not assigning
myself until I get further though.
