[PATCH] D116366: [Support] Add MemoryBuffer::dontNeedIfMmap

[David Tenty via Phabricator via llvm-commits]

daltenty added a comment.

> Unfortunately this change broke AIX build since MADV_DONTNEED is not available. Is there any other OS without MADV_DONTNEED? Can this be reverted until we find alternative?

Maybe we can swap to `posix_madvise` if the semantics match what we need here? That should be available on AIX.
