New Revision: 158644
URL: http://llvm.org/viewvc/llvm-project?rev=158644&view=rev
Log:
Remove SmallMap, and the several files that were used to implement it.
We have SmallDenseMap now that has more correct and predictable
semantics, even though it is a more narrow abstraction.
Removed:
llvm/trunk/include/llvm/ADT/FlatArrayMap.h
llvm/trunk/include/llvm/ADT/MultiImplMap.h
llvm/trunk/include/llvm/ADT/SmallMap.h
