New Revision: 275745
URL: http://llvm.org/viewvc/llvm-project?rev=275745&view=rev
Log:
Implement C++17 tuple bits. Including apply and make_from_tuple.
This patch upgrades <tuple> to be C++17 compliant by implementing:
* tuple_size_v: This was forgotten when implementing the other _v traits.
* std::apply: This was added via LFTS v1 in p0220r1.
* std::make_from_tuple: This was added in p0209r2.
