--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
So the issue is that in WPA we mix:
void a() __asm__("open64");
and
void open64() {}
Then we stream out:
*open64/0 (a) @0x7ffff698f5a0
Type: function definition analyzed
Visibility: externally_visible prevailing_def_ironly_exp public
Address is taken.
References:
Referring: e/2 (addr)
Read from file: open64.o
Availability: overwritable
Function flags: count:1073741824 (estimated locally)
Called by:
Calls: c/4 (1073741824 (estimated locally),1.00 per call) b/3 (1073741824
(estimated locally),1.00 per call)
and in ltrans the function body of the cgraph node looks as follows:
$2 = void
(gdb) p debug_function(fn_decl, 0)
a ()
{
<bb 2> [local count: 1073741824]:
return;
}
which has no calls, thus the discrepancy in cgraph edges. I think it's the same
issue as PR87525. So Honza's turn.
