This is an unofficial snapshot of the ISO/IEC JTC1 SC22 WG21 Core Issues List revision 108i. See http://www.open-std.org/jtc1/sc22/wg21/ for the official list.
[Adopted at the June, 2016 meeting.]
The resolution of issue 1816 left many aspects of bit-fields unspecified, including whether a signed bit field has a sign bit and the meaning of the bit-field width. Also, the requirement in 6.8.2 [basic.fundamental] paragraph 1 that
For narrow character types, all bits of the object representation participate in the value representation.
should not apply to oversize character-typed bit-fields.
Notes from the June, 2014 meeting:
CWG decided to address only the issue of oversized bit-fields of narrow character types at this time, splitting off the more general questions regarding bit-fields to issue 1943.
Proposed resolution (April, 2016):
Change 6.8.2 [basic.fundamental] paragraph 1 as follows:
...For narrow character types, all bits of the object representation participate in the value representation. For unsigned narrow character types, each possible bit pattern of the value representation represents a distinct number...
