Bug ID: 95094
Summary: alignof(reference_to_type) doesn't return
alignof(referenced_type) as it ought to, by the
standard
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: sinbal2l at gmail dot com
Target Milestone: ---
>From the C++ standard:
7.6.2.5 Alignof [expr.alignof]p3
3 When alignof is applied to a reference type, the result is the alignment of
the *referenced* type.
IINM, in the latest version, the returned value is of the reference itself:
#include <stdio.h>
int main() {
alignas(32) double d;
double &ref_d = d;
printf("Alignment of d: %d\n", alignof(d)); // 32
printf("Alignment of ref_d: %d\n", alignof(ref_d)); // 8
}
