I might be a bit rusty in my x86 assembly, but wouldn't "repnz movsb" be the x86 strcpy opcode, for zero-terminated strings?

		Not a thing unfortunately; you can only use the rep prefix with movable.

Real men just blast through memory until hitting a zero. If it's there at all.

If you care at least a little about buffer overflows You will run one anyway.

		If you want a strlen+memcpy you are more than welcome to call it yourself
