Bug ID: 68061
Summary: Can't use [[deprecated]] with requires clause
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: chrisb2244 at gmail dot com
Target Milestone: ---
Either of
template<ConceptName... parameter> requires RequiresConcept<A, parameter...>
const T x(const parameter... p) const { ... }
or
template<ConceptName... parameter, std::enable_if<...>
[[deprecated]] const T x(const parameter... p) const { ... }
will compile (using 'g++-trunk -std=c++1z ...')
Using the 'requires' clause along with an attempt to deprecate the function
using [[deprecated]] produces
"two consecutive '[' shall only introduce an attribute before '[' token"
