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