— invocation: Make all offsets constants
This makes the assembly much more readable.
No difference between disassembled .o file before and after. (user: js, size: 2945) [annotate] [blame] [check-ins using]

— Replace a few movdqa with movaps
movaps is smaller, and we don't know what kind of data is in there

does not matter which move instruction we use. (user: js, size: 2945) [annotate] [blame] [check-ins using]
