--- Comment #2 from kugan at gcc dot gnu.org ---
In ipa-prop.c, function ipa_compute_jump_functions_for_edge called from
determine_locally_known_aggregate_parts doesn't compute jump functions for
aggregates when they are initialized during definition.
If I change the testcase to following, it works.
typedef struct F {
int (*call)(int);
} F;
static int g(F f, int x) {
x = f.call(x);
x = f.call(x);
x = f.call(x);
x = f.call(x);
x = f.call(x);
x = f.call(x);
x = f.call(x);
x = f.call(x);
return x;
}
static int sq(int x) {
return x * x;
}
static F f = {sq};
//static const F f = {sq};
void dosomething(int);
int h(int x) {
f.call = sq;
dosomething(g(f, x));
dosomething(g((F){sq}, x));
}
I guess, for the varpool_node corresponding to static const F f = {sq};, we
have to check hat the initialization are constant and create the jump function.
I still haven't figured out how I can get the initialization list for the
structure. Any pointers?
varpool_node *node = varpool_node::get (arg); should get me to the varpool
node.
