faload : retrieve float from array : index : visitInsn()

Description

Retrieves an entry from a float array and places it on the stack. arrayref is a reference to an array of single-precision floats. index is an int. The arrayref and index are removed from the stack, and the single-precision float entry at the given index in the array is pushed onto the stack.

Example

; This is like the Java code:
;     float x = arr[0];
; where x is local variable 2 and arr is a float
; array in local variable 1
aload_1       ; load local variable 1 onto the stack
iconst_0      ; push the integer 0 onto the stack
faload        ; retrieve the entry
fstore_2      ; store the entry in local variable 2

Exceptions

NullPointerException - arrayref is null

ArrayIndexOutOfBoundsException - index is < 0 or >= arrayref.length

Notes

Array indices start at 0 (the first entry in the array is at index 0).
