commit 1410d22cac55c325dc437fb4575465001e65fe97 Author: Alex Richardson <[email protected]> AuthorDate: 2025-09-15 22:14:18 +0000 Commit: Ed Maste <[email protected]> CommitDate: 2026-01-08 17:14:06 +0000 libc++: silence -Wnontrivial-memaccess warning with newer clang Apply part of LLVM commit 71315698c91d0cda054b903da0594ca6f072c350 to silence the -Wnontrivial-memaccess warning that is triggered any time this function is instantiated by user code. This fixes another buildworld failure with Clang HEAD. Original commit message: [clang] Warn about memset/memcpy to NonTriviallyCopyable types (#111434) This implements a warning that's similar to what GCC does in that context: both memcpy and memset require their first and second operand to be trivially copyable, let's warn if that's not the case.
