2511. cv-qualified bit-fields

Section: 11.4.10  [class.bit]     Status: CD6     Submitter: Aaron Ballman     Date: 2021-09-15

[Accepted at the February, 2022 meeting.]

According to 11.4.10 [class.bit] paragraph 1,

A bit-field shall have integral or enumeration type

This apparently does not allow for cv-qualification in a bit-field type.

Notes from the December, 2021 meeting:

As of N4901, there is no longer an issue regarding the integral types; 6.8.2 [basic.fundamental] paragraph 11 says,

The character types, bool, the signed and unsigned integer types, and cv-qualified versions (6.8.5 [basic.type.qualifier]) thereof, are collectively termed integral types.

Proposed resolution (December, 2021):

A bit-field shall have integral or (possibly cv-qualified) enumeration type
