dmd saves some registers before the asm code, and then restores 
them after your asm. If you don't want that behavour then you 
have to use the "naked" attribute.

For details of what registers can be used take a look at the 
docs. And also take a look at the disassembly of your function 
that contains an empty asm statement, to see exactly what's saved.
