# This file provides information to the optimizer about the behaviour of
# functions and events. This knowledge can help perform a better job at
# optimizing. All functions and events present in builtins.txt must be here
# and vice versa.

# Flags are entered with a dash at the beginning of the line, then a space,
# then the flag. Flags apply to the function they are under. There can be none
# before the first function.
#
# Available flags:
#
#  stable:
#    Two successive calls with the same parameters are assumed to return
#    the same results in most reasonable cases. When it's stable and SEF
#    it's posible to simplify two identical calls into one. Example:
#    llGetPermissions(). Counterexample: llFrand(). This is the default;
#    unstable functions must be marked as such. Does not apply to void
#    functions. This flag is not implemented; 'unstable' is.
#
#  unstable:
#    Not stable. This flag IS implemented.
#
#  strlen:
#    Marks the function as accepting one unique parameter of type string,
#    and returning 0 is equivalent to the parameter being an empty string.
#
#  detect:
#    Marks the function/event as being a detection one.
#
#  touch:
#    Marks the event as being a touch event.
#
#  grab:
#    Marks the event as enabling grab detection.
#
#  delay <value>:
#    Function has a delay.
#
#  SEF [if <condition>]:
#    Side-effect free. The function has no side effects when executed,
#    which means that when used in a situation where it does nothing,
#    it can be removed without affecting execution. Example:
#    llGetNumberOfPrims(). All functions with delay have a side effect
#    (the delay itself).
#
#    With if <condition>, the function is SEF if the parameters are
#    found to meet the condition. Syntax of <condition> is explained below.
#
#  min:
#    Applied to functions that return integer or float. Specifies the
#    minimum value it may return. If not present, assume the minimum
#    possible (-inf for floats, -2147483648 for integers). Use like this:
#
#     - min <min value>
#
#  max:
#    Like min, but for the maximum value.
#
#  listto:
#    Identifies the function as a list-extracting function, for use with
#    lazy lists. It needs an LSL type as a parameter.
#
#  return <value> [if <condition>]:
#    Self-explanatory. There can be several; they are evaluated in order.
#    <value> can be a parameter or a LSL constant. <condition> is explaned
#    below.
#
#  <condition>
#    Subset of LSL expressions using only (, ), ==, !=, <, <=, >, >=,
#    &&, ||, constants, function parameters and one function. As an extension,
#    Python-like operator chaining works, e.g. a < b < c or a == b == c.
#    && has more priority than ||.
#    The type of comparisons is bool and can't be used as integer.
#    Lists are compared for equal. Elements in lists, vectors and
#    rotations must be constants.
#
#    ['<' and '>' need spaces around them when they are comparisons;
#    vectors need to have no space after '<' or before '>'.] -> Let's not,
#    and see what happens.
#
#    Strings are automatically type cast to key when necessary, and integers
#    to floats, but not vice versa. Function bool nulluuid(key k) is allowed.
#
#    There's a pseudo-parameter of type string that is always available:
#    event (the event where the function is called, if known; else "")

# A comment like this:
#
# physics caveat
#
# means that tests show it's apparently stable because physics are
# recomputed every frame, and the frame doesn't change that often.
