30 /* A jump function for a callsite represents the values passed as actual
31 arguments of the callsite. They were originally proposed in a paper called
32 "Interprocedural Constant Propagation", by David Callahan, Keith D Cooper,
33 Ken Kennedy, Linda Torczon in Comp86, pg 152-161. There are three main
34 types of values :
36 Pass-through - the caller's formal parameter is passed as an actual
37 argument, possibly one simple operation performed on it.
38 Constant - a constant (is_gimple_ip_invariant)is passed as an actual
39 argument.
40 Unknown - neither of the above.
42 IPA_JF_ANCESTOR is a special pass-through jump function, which means that
43 the result is an address of a part of the object pointed to by the formal
44 parameter to which the function refers. It is mainly intended to represent
45 getting addresses of of ancestor fields in C++
46 (e.g. &this_1(D)->D.1766.D.1756). Note that if the original pointer is
47 NULL, ancestor jump function must behave like a simple pass-through.
49 Other pass-through functions can either simply pass on an unchanged formal
50 parameter or can apply one simple binary operation to it (such jump
51 functions are called polynomial).
53 Jump functions are computed in ipa-prop.c by function
54 update_call_notes_after_inlining. Some information can be lost and jump
55 functions degraded accordingly when inlining, see
56 update_call_notes_after_inlining in the same file. */
