Jakob Stoklund Olesen 52d6dd3079 Add ADT/IntervalMap. ... This is a sorted interval map data structure for small keys and values with automatic coalescing and bidirectional iteration over coalesced intervals. Except for coalescing intervals, it provides similar functionality to std::map. It is however much more compact for small keys and values, and hopefully faster too. The container object itself can hold the first few intervals without any allocations, then it switches to a cache conscious B+-tree representation. A recycling allocator can be shared between many containers, even between containers holding different types. The IntervalMap is initially intended to be used with SlotIndex intervals for: - Backing store for LiveIntervalUnion that is smaller and faster than std::set. - Backing store for LiveInterval with less overhead than std::vector for typical intervals and O(N log N) merging of large intervals. 99% of virtual registers need 4 entries or less and would benefit from the small object optimization. - Backing store for LiveDebugVariable which doesn't exist yet, but will track debug variables during register allocation. This is a work in progress. Missing items are: - Performance metrics. - erase(). - insert() shrinkage. - clear(). - More performance metrics. - Simplification and detemplatization. llvm-svn: 119787		2010-11-19 04:47:19 +00:00
