Clang is gaining `auto(x)` support in D113393; sadly there seems to be no feature-test macro for it. Zhihao is opening a core issue for that macro. Use `_LIBCPP_AUTO_CAST` where C++20 specifies we should use `auto(x)`; stop using `__decay_copy(x)` in those places. In fact, remove `__decay_copy` entirely. As of C++20, it's purely a paper specification tool signifying "Return just `x`, but it was perfect-forwarded, so we understand you're going to have to call its move-constructor sometimes." I believe there's no reason we'd ever need to do its operation explicitly in code. This heisenbugs away a test failure on MinGW; see D112214. Differential Revision: https://reviews.llvm.org/D115686 |
