2010-11-19Add an assert.Rafael Espindola
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119788 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

2010-11-19unittests/CMakeLists.txt: Suppress building ValueMapTest on MSVC older than ↵NAKAMURA Takumi

2010-11-19Change some methods in MCDwarf.cpp to be able to handle an arbitraryRafael Espindola
MCStreamer instead of just MCObjectStreamer. Address changes cannot be as efficient as we have to use DW_LNE_set_addres, but at least most of the logic is shared. This will be used so that, with CodeGen still using EmitDwarfLocDirective, llvm-gcc is able to produce debug_line sections without needing an assembler that supports .loc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119777 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-19Add MC encodings for some Thumb instructions. Test for a few of them. The "bxBill Wendling

2010-11-18Fix bug in DAGCombiner for ARM that was trying to do a ShiftCombine on ↵Tanya Lattner
illegal types (vector should be split first). Added test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119749 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-18Change the 'x' type modifier for Neon intrinsics to force a signed integer.Bob Wilson
This makes it symmetric with the 'u' modifier that forces an unsigned type. This is needed for unsigned vector shifts, where the shift amount still needs to be signed. PR8482 (Radar 8603521). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119742 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-18Fix thinko: we must turn select(anyext, sext) into sext(select)Duncan Sands
not anyext(select). Spotted by Frits van Bommel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119739 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-18Split up ARM LowerShift function.Bob Wilson
This function was being called from two different places for completely unrelated reasons. During type legalization, it was called to expand 64-bit shift operations. During operation legalization, it was called to handle Neon vector shifts. The vector shift code was not written to check for illegal types, since it was assumed to be only called after type legalization. Fixed this by splitting off the 64-bit shift expansion into a separate function. I don't have a particular testcase for this; I just noticed it by inspection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119738 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-18The DAGCombiner was threading select over pairs of extending loads evenDuncan Sands
if the extension types were not the same. The result was that if you fed a select with sext and zext loads, as in the testcase, then it would get turned into a zext (or sext) of the select, which is wrong in the cases when it should have been an sext (resp. zext). Reported and diagnosed by Sebastien Deldon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119728 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-18Factor code for testing whether replacing one value with anotherDuncan Sands
preserves LCSSA form out of ScalarEvolution and into the LoopInfo class. Use it to check that SimplifyInstruction simplifications are not breaking LCSSA form. Fixes PR8622. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119727 91177308-0d34-0410-b5e6-96231b3b80d8
