Inside the module: Just look at the assembler listing. Alignment added by the linker: Generate a map file and enable "verbose map" by -vm. The modules list will show the offsets and sizes of date that goes into a specific segment. For your example, it looks like this: Modules list: ------------- collision.o: CODE Offs = 000000 Size = 000000 RODATA Offs = 000000 Size = 000000 BSS Offs = 000000 Size = 000000 DATA Offs = 000000 Size = 000000 ZEROPAGE Offs = 000000 Size = 000000 NULL Offs = 000000 Size = 000000 CODE1 Offs = 000000 Size = 0002A3 map.o: CODE Offs = 000000 Size = 000000 RODATA Offs = 000000 Size = 000000 BSS Offs = 000000 Size = 000000 DATA Offs = 000000 Size = 000000 ZEROPAGE Offs = 000000 Size = 000000 NULL Offs = 000000 Size = 000000 CODE1 Offs = 000400 Size = 001792 What you can see is that collision.o starts the CODE1 segment at offset $0 and emits $2A3 bytes, but the following module, map.o starts at offset $400, so actually $400-$2A3 = $15D bytes are wasted (this is also the number I mentioned in my previous mail:-).
