Bug ID: 101400
Summary: comments mention gnu-attributes[opt] even though it
can be empty
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: roland.illig at gmx dot de
Target Milestone: ---
gcc/c/c-parser.c says:
> gnu-attributes:
> empty
> gnu-attributes gnu-attribute
Several other comments in that file refer to that grammar rule as
gnu-attributes[opt]. The [opt] is not necessary in those references.
To avoid confusion, the [opt] should be removed from the references.
Apart from potentially confusing readers of the code, there is no actual
problem.
