Bug ID: 88101
Summary: Implement P0528R3, C++20 cmpxchg and padding bits
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: jason at gcc dot gnu.org
Target Milestone: ---
Although this paper was moved by Core at the meeting, it's a change to the
library atomics clause. Do you need compiler support for this? It seems
fairly straightforward to handle types for which
has_unique_object_representations is false by zeroing the storage as the first
step of initialization.
