Bug ID: 109741
Summary: alignas(64) in libstdc++-v3/src/c++11/shared_ptr.cc
Product: gcc
Version: 13.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: janezz55 at gmail dot com
Target Milestone: ---
This line:
struct alignas(64) M : __gnu_cxx::__mutex { };
has been an eyesore for me for a number of years. I propose to change it into:
struct alignas(std::max_align_t) M : __gnu_cxx::__mutex { };
in which case <cstddef> needs to be #included as well. The magic number 64
alone should be raising some eyebrows and some targets do not support this
alignment.
