// Intr*Mem - Memory properties.  If no property is set, the worst case
// is assumed (it may read and write any memory it can get access to and it may
// have other side effects).

// IntrNoMem - The intrinsic does not access memory or have any other side
// effects.  It may be CSE'd deleted if dead, etc.
def IntrNoMem : IntrinsicProperty;

// IntrReadMem - This intrinsic only reads from memory. It does not write to
// memory and has no other side effects. Therefore, it cannot be moved across
// potentially aliasing stores. However, it can be reordered otherwise and can
// be deleted if dead.
def IntrReadMem : IntrinsicProperty;

// IntrWriteMem - This intrinsic only writes to memory, but does not read from
// memory, and has no other side effects. This means dead stores before calls
// to this intrinsics may be removed.
def IntrWriteMem : IntrinsicProperty;

// IntrArgMemOnly - This intrinsic only accesses memory that its pointer-typed
// argument(s) points to, but may access an unspecified amount. Other than
// reads from and (possibly volatile) writes to memory, it has no side effects.
def IntrArgMemOnly : IntrinsicProperty;

// IntrInaccessibleMemOnly -- This intrinsic only accesses memory that is not
// accessible by the module being compiled. This is a weaker form of IntrNoMem.
def IntrInaccessibleMemOnly : IntrinsicProperty;

// IntrInaccessibleMemOrArgMemOnly -- This intrinsic only accesses memory that
// its pointer-typed arguments point to or memory that is not accessible
// by the module being compiled. This is a weaker form of IntrArgMemOnly.

// arguments of the intrinsic wrt. the intrinsic scope.

// control-dependent on any additional values.

// This property can be used to override the 'has no other side effects'
// language of the IntrNoMem, IntrReadMem, IntrWriteMem, and IntrArgMemOnly
// intrinsic properties.  By default, intrinsics are assumed to have side
// effects, so this property is only necessary if you have defined one of
// the memory properties listed above.
