imm8_form A3
Description:
The two source operands are logically ANDed and the result placed in GR
r
1
. In the
register_form the first operand is GR
r
2
; in the imm8_form the first operand is taken
from the
imm
8
encoding field.
Operation: if (PR[ qp ]) {
check_target_register( r
1
);
tmp_src = (register_form ? GR[ r
2
] : sign_ext( imm
8
, 8));
tmp_nat = (register_form ? GR[ r
2
].nat : 0);
GR[ r
1
] = tmp_src & GR[ r
3
];
GR[ r
1
].nat = tmp_nat || GR[ r
3
].nat;
