$/*$

op shl: set $*$ to $*$AA shifted by $*$CNT position to the left, and set the flags

of CPU STZTE accordingly. $*$CNT is a l$-$byte unsigned integer.

RESTRICTIONS: You are allowed to use uint$8$ t and uint$8$ t$*$ as types.

No other type is allowed. No call to external functions.

tARNING: Do NOT modify $*$CNT$.$ Make a local copY. If you modify $*$CNT$,$ the

tester will fail with a strange behavior.

FLIAGS:

OF: Becomes $1$ if the two most significant bits of the starting value

of $**A$ were different, $0$ otherwise.

ZF: $1$ if the final value of $*$A is zero, $0$ otherwise.

SF: $1$ if the final value of $*$A is negative, $0$ otherwise.
