10// This file implements a mapping from windows errors to posix ones.
11// The standard doesn't define what the equivalence is from system
12// errors to generic ones. The one implemented in msvc is too conservative
13// for llvm, so we do an extra mapping when constructing an error_code
14// from an windows error. This allows the rest of llvm to simple checks
15// like "EC == std::errc::file_exists" and have it work on both posix and
16// windows.
