Bug ID: 105550
Summary: Missing copy elision with conditional operator in
NSDMI
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mpolacek at gcc dot gnu.org
Target Milestone: ---
Consider:
struct A {
const A* p = this;
};
struct E {
A a = true ? A{} : A{};
};
constexpr E e{};
$ ./cc1plus -quiet q.C
q.C:9:15: error: ‘E{A{((const A*)(&<anonymous>))}}’ is not a constant
expression
9 | constexpr E e{};
| ^
The ?: shouldn't preclude copy elision. 'e' must be static for this to work.
Bug 96004 with a similar title doesn't seem to be a duplicate of this one.
