; Returns the index of the first element matching the provided predicate function (or -1 if not found)
; Arguments:
; r1 - The array pointer
; r2 - The array length (number of items)
; r3 - The stride (size of one item) - either 1, 2 or 4 (bytes)
; r4 - The predicate
; r5 - Predicate context
; Result:
; r1 - The index of the first element matching the provided predicate function (or -1 if not found)
; Clobbers: r2, r3, r4, r5, r6, + what the predicate clobbers
; Info:
; The predicate function should follow the stdlib calling convention
; The predicate receives two arguments (the value and the predicate context) and should return either a zero when the value is not the one we search for
; , or any other result if it is the searched-for item.
