Bug ID: 88466
Summary: Support std::hardware_destructive_interference_size
and std:: hardware_constructive_interference_size
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: duarte at scylladb dot com
Target Milestone: ---
The following should compile:
#include <new>
struct x {
alignas(std::hardware_destructive_interference_size) int y;
alignas(std::hardware_constructive_interference_size) int z;
};
It seems, however, that neither std::hardware_destructive_interference_size nor
std::hardware_constructive_interference_size have been included in libstdc++.
