2010-12-01Delete Path::appendSuffix's return value; it wasn't used anywhere, whichDan Gohman
is fine since isn't really necessary to check isValid there anyway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120538 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-26Move tree navigation to a new Path class that doesn't have to be a template.Jakob Stoklund Olesen
The path also holds a reference to the root node, and that allows important iterator accessors like start() and stop() to have no conditional code. (When the compiler is clever enough to remove it.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120165 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-23add a MemoryBuffer::getOpenFile method, which turns an openChris Lattner
file descriptor into a MemoryBuffer (and closes the FD). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120065 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-19Add ADT/IntervalMap.Jakob Stoklund Olesen
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119787 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-17now that AsmPrinter::EmitInlineAsm is factored right, we can eliminate theChris Lattner
cookie argument to the SourceMgr diagnostic stuff. This cleanly separates LLVMContext's inlineasm handler from the sourcemgr error handling definition, increasing type safety and cleaning things up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119486 91177308-0d34-0410-b5e6-96231b3b80d8
