I look at the `objdump'ed assembly file again and I find that all functions start at the address which is 8-byte aligned. Is there a particular good reason for 8-byte alignment, even if the target ARCH is 32-bit rather than 64-bit and aligment is quite a little waste of storage and runtime memory? >It's probably caused by requested alignment of the next function. >Note that nop is just the value 0. > >To see whether gcc is actually generating the nop, use the >--save-temps option when you compile, and look at the .s file.
