Bug ID: 110845
Summary: Function call when it should inline?
Product: gcc
Version: 13.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: deco33000 at yandex dot com
Target Milestone: ---
Hi,
The below code is inlined in clang (trunk) but not in gcc (13.2).
The code:
#include <format>
#include <iostream>
using namespace std;
constexpr auto f(bool a) -> void {
if (a) {
cout << format("hello 1\n");
} else {
cout << format("hello 2\n");
}
}
template <bool T>
constexpr auto g() -> void {
if constexpr (T) {
cout << format("hello 3\n");
} else {
cout << format("hello 4\n");
}
}
int main() {
f(true);
f(false);
g<true>();
g<false>();
}
flags = -std=c++23 -O3
You can see/test the Godbolt here:

Maybe it is related to "format" because without it, it inlines properly.
