Bug ID: 41591
Summary: LWG 3062 Unnecessary decay_t in is_execution_policy_v
should be remove_cvref_t
Product: parallel STL
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: New
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
https://cplusplus.github.io/LWG/issue3062 says to replace std::decay with
std::remove_cvref, which means in the __enable_if_execution_policy helper in
pstl/execution_defs.h:
namespace __internal
{
template <class ExecPolicy, class T>
using __enable_if_execution_policy =
typename std::enable_if<__pstl::execution::is_execution_policy<typename
std::remove_reference<ExecPolicy>::type>::value,
T>::type;
} // namespace __internal
As remove_cvref is only available since C++2a it might have to be typename
remove_cv<typename remove_reference<ExecPolicy>::type>::type instead, but that
should still be more efficient to compile than std::decay.
