Typedefs
template<template< class... > class Op, class... Args>
using	llvm::is_detected = typename detail::detector<void, Op, Args...>::value_t

Detailed Description

This file contains library features backported from future STL versions.

These should be replaced with their STL counterparts as the C++ version LLVM is compiled with is updated.
