Bug ID: 70382
Summary: Attribute not supported on bit-field declarations
Product: gcc
Version: 5.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: aaron.ballman+gcc at gmail dot com
Target Milestone: ---
The following code produces a reject-valid diagnostic:
struct test {
unsigned d [[]] : 1;
};
main.cpp:2:17: error: function definition does not declare parameters
unsigned d [[]] : 1;
^
[class.bit]p1 (in part):
A member-declarator of the form
identifieropt attribute-specifier-seqopt: constant-expression
specifies a bit-field; its length is set off from the bit-field name by a
colon. The optional attribute-specifierseq appertains to the entity being
declared.
MSVC and Clang both accept.
