This patch adds the `memalignment` function to LLVM-libc, following its description in [WG14 N3220, §7.24.2.1](https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3220.pdf#page=387). - [x] Add the implementation of `memalignment` in [`/src/stdlib`](https://github.com/llvm/llvm-project/tree/main/libc/src/stdlib) - [x] Add tests for `memalignment` in [`/test/src/stdlib`](https://github.com/llvm/llvm-project/tree/main/libc/test/src/stdlib) - [x] Add `memalignment` to [`entrypoints.txt`](https://github.com/llvm/llvm-project/blob/main/libc/config/linux/x86_64/entrypoints.txt) for at least x86_64 and whatever you're building on - [x] Add `memalignment` to [`include/stdlib.yaml`](https://github.com/llvm/llvm-project/blob/main/libc/include/stdlib.yaml) Closes #132300 --------- Co-authored-by: Joseph Huber <huberjn@outlook.com>
