Bug ID: 88985
Summary: [9 Regression] ICE in estimate_edge_devirt_benefit, at
ipa-fnsummary.c:2585
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Changed between 20180610 and 20180624, at -O0 on x86_64 GNU/Linux :
$ cat z1.c
void f (void)
{
}
__attribute__((__optimize__("O2")))
void g (void f())
{
f();
}
__attribute__((__optimize__("O2")))
void h (void)
{
g(f);
}
