New Revision: 260752
URL: http://llvm.org/viewvc/llvm-project?rev=260752&view=rev
Log:
Data formatter support for libc++ std::atomic<T>
On libc++ std::atomic is a fairly simple data type (layout wise, at least), wrapping actual contents in a member variable named "__a_"
All the formatters are doing is "peel away" this intermediate layer and exposing user data as direct children or values of the std::atomic root variable
Fixes rdar://24329405
