expected.bad	[libc++] Implement std::expected P0323R12 Implement std::expected https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/p0323r12.html Added tests Differential Revision: https://reviews.llvm.org/D124516 address comment	3 年前
expected.expected	[libc++] Fix UB in <expected> related to "has value" flag (#68552) (#68733) The calls to std::construct_at might overwrite the previously set __has_value_ flag in the case where the flag is overlapping with the actual value or error being stored (since we use [[no_unique_address]]). To fix this issue, this patch ensures that we initialize the __has_value_ flag after we call std::construct_at. Fixes #68552 (cherry picked from commit 134c91595568ea1335b22e559f20c1a488ea270e)	2 年前
