35/* A jump function for a callsite represents the values passed as actual
36 arguments of the callsite. They were originally proposed in a paper called
37 "Interprocedural Constant Propagation", by David Callahan, Keith D Cooper,
38 Ken Kennedy, Linda Torczon in Comp86, pg 152-161. There are three main
39 types of values :
40
41 Pass-through - the caller's formal parameter is passed as an actual
42 argument, possibly one simple operation performed on it.
43 Constant - a constant (is_gimple_ip_invariant)is passed as an actual
44 argument.
45 Unknown - neither of the above.
46
47 IPA_JF_LOAD_AGG is a compound pass-through jump function, in which primary
48 operation on formal parameter is memory dereference that loads a value from
49 a part of an aggregate, which is represented or pointed to by the formal
50 parameter. Moreover, an additional unary/binary operation can be applied on
51 the loaded value, and final result is passed as actual argument of callee
52 (e.g. *(param_1(D) + 4) op 24 ). It is meant to describe usage of aggregate
53 parameter or by-reference parameter referenced in argument passing, commonly
54 found in C++ and Fortran.
55
56 IPA_JF_ANCESTOR is a special pass-through jump function, which means that
57 the result is an address of a part of the object pointed to by the formal
58 parameter to which the function refers. It is mainly intended to represent
59 getting addresses of ancestor fields in C++
60 (e.g. &this_1(D)->D.1766.D.1756). Note that if the original pointer is
61 NULL, ancestor jump function must behave like a simple pass-through.
62
63 Other pass-through functions can either simply pass on an unchanged formal
64 parameter or can apply one simple binary operation to it (such jump
65 functions are called polynomial).
66
67 Jump functions are computed in ipa-prop.cc by function
68 update_call_notes_after_inlining. Some information can be lost and jump
69 functions degraded accordingly when inlining, see
70 update_call_notes_after_inlining in the same file. */
