land : long integer bitwise and : index : visitInsn()

Description

Pops two long integers off the stack. Computes the bitwise and of value1 and value2. The long integer result replaces value1 and value2 on the stack.

Example

; This is like the Java code:
;       long x;
;       x &= 1;
;
lload_1          ; push the long integer in local variable 1
lconst_1         ; push the integer 1 onto the stack
land             ; compute the bitwise and
lstore_1         ; store the long result in local variable 1
