[libcxx-commits] [PATCH] D89057: Add the C++17 <memory_resource> header (mono-patch)

[Arthur O'Dwyer via Phabricator via libcxx-commits]

Quuxplusone updated this revision to Diff 308041.
Quuxplusone added a comment.

Renamed `chunk_header` to `chunk_footer` and the corresponding `header_{size,align}` to `footer_{size,align}`. This actually makes the math in `aligned_capacity` easier to understand, IMO!  I left the loop variable `h` alone, rather than rename it to `f`, because `f` seems uglier to me.

I left `vacancy_header` alone, because it is actually stored in the initial bytes of the chunk. (Right?)

So far, I've left `initial_header` alone, even though technically it is neither a header //nor// a footer, because it is stored outside of the initial buffer. Perhaps it could be renamed something like `initial_info`? Any thoughts on terminology there, @griwes?

Also in this update I've merged in a couple of threading-related fixes that have been made to `<experimental/memory_resource>` in the past year.
