[libcxx-commits] [PATCH] D56398: Add new EINTEGRITY errno

[Dimitry Andric via Phabricator via libcxx-commits]

dim updated this revision to Diff 225929.
dim added a comment.

Get rid of the ELAST trickery, which is hard to maintain, and does not
appear to serve any purpose.  There is no mention of ELAST in the C or
C++ standards, as far as I know.

Then, simply add the new EINTEGRITY define at the end with a unique
value, if it does not yet exist.

  rCXX libc++
