Proposed resolution:
This wording is relative to N4971.
Modify [depr.c.macros] as indicated:
-1- The header <stdalign.h> has the following macros:
#define __alignas_is_defined 1 #define __alignof_is_defined 1
[ Tokyo 2024-03-23; Status changed: Voting → WP. ]
[ 2024-03-12; Reflector poll ]
Set status to Tentatively Ready after seven votes in favour during reflector poll.
Currently [stdalign.h.syn] states
The contents of the C++ header <stdalign.h> are the same as the C standard library header <stdalign.h>, with the following changes: The header <stdalign.h> does not define a macro named alignas.
See also: ISO/IEC 9899:2018, 7.15
which implicitly specifies that __alignof_is_defined is also provided in C++, because C17 specified that the macro is provided in <stdaligh.h>.
However, there's no explicit mentioning of __alignof_is_defined in the C++ standard wording. And [depr.c.macros]/1 (added by LWG 3827) seemingly contradicts with [stdalign.h.syn] and only makes __alignas_is_defined deprecated. It seems that we should explicitly mention __alignof_is_defined in [depr.c.macros] at this moment.| History | |||
