[RFC][InlineCost] Modeling JumpThreading (or similar) in inline cost model
...ing on an improvement to the inline cost model, but I'm unsure
how to proceed. Let me begin by first describing the problem I'm trying
to solve. Consider the following pseudo C code:
*typedef struct element {
unsigned idx;
} element_t;
*
*static inline
unsigned char fn2 (element_t *dst_ptr, const element_t *a_ptr,
const element_t *b_ptr, unsigned char changed) {
if (a_ptr && b_ptr && a_ptr->idx == b_ptr->idx) {
if (!changed && dst_ptr && dst_ptr->idx == a_ptr->idx) {
/* Do something */
} else {...

[RFC][InlineCost] Modeling JumpThreading (or similar) in inline cost model
...y one of them has the property that the 1st and 2nd argument are the same (as is shown in my pseudo code). Internally, we have another developer, Matt Simpson, working on a function specialization patch that might be of value here. Specifically, you could clone fn2 based on the fact that a_ptr == dst_ptr and then simplify a great deal of the function. However, that patch is still a WIP.
GCC will do IPA-CP/const-prop with cloning, and i'm wildly curious if new GCC's catch this case for you at higher optimization levels?
GCC does inline fn2 into fn1 in this particular case, but I'm no...
