* Added FMA3 Intel instructions.Elena Demikhovsky2012-05-316-49/+409
| | | | | | | | | | I disabled FMA3 autodetection, since the result may differ from expected for some benchmarks. I added tests for GodeGen and intrinsics. I did not change llvm.fma.f32/64 - it may be done later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157737 91177308-0d34-0410-b5e6-96231b3b80d8

* Prioritize smaller register classes for urgent evictions.Jakob Stoklund Olesen2012-05-301-1/+7
| | | | | | | | | | | | | | It helps compile exotic inline asm. In the test case, normal GR32 virtual registers use up eax-edx so the final GR32_ABCD live range has no registers left. Since all the live ranges were tiny, we had no way of prioritizing the smaller register class. This patch allows tiny unspillable live ranges to be evicted by tiny unspillable live ranges from a smaller register class. <rdar://problem/11542429> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157715 91177308-0d34-0410-b5e6-96231b3b80d8

* Teach SCEV's icmp simplification logic that a-b == 0 is equivalent to a == b.Benjamin Kramer2012-05-301-1/+20
| | | | | | | | | | | | | | | This also required making recursive simplifications until nothing changes or a hard limit (currently 3) is hit. With the simplification in place indvars can canonicalize loops of the form for (unsigned i = 0; i < a-b; ++i) into for (unsigned i = 0; i != a-b; ++i) which used to fail because SCEV created a weird umax expr for the backedge taken count. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157701 91177308-0d34-0410-b5e6-96231b3b80d8

* PR1255: Case RangesStepan Dyatkovskiy2012-05-288-15/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Implemented IntItem - the wrapper around APInt. Why not to use APInt item directly right now? 1. It will very difficult to implement case ranges as series of small patches. We got several large and heavy patches. Each patch will about 90-120 kb. If you replace ConstantInt with APInt in SwitchInst you will need to changes at the same time all Readers,Writers and absolutely all passes that uses SwitchInst. 2. We can implement APInt pool inside and save memory space. E.g. we use several switches that works with 256 bit items (switch on signatures, or strings). We can avoid value duplicates in this case. 3. IntItem can be easyly easily replaced with APInt. 4. Currenly we can interpret IntItem both as ConstantInt and as APInt. It allows to provide SwitchInst methods that works with ConstantInt for non-updated passes. Why I need it right now? Currently I need to update SimplifyCFG pass (EqualityComparisons). I need to work with APInts directly a lot, so peaces of code ConstantInt *V = ...; if (V->getValue().ugt(AnotherV->getValue()) { ... } will look awful. Much more better this way: IntItem V = ConstantIntVal->getValue(); if (AnotherV < V) { } Of course any reviews are welcome. P.S.: I'm also going to rename ConstantRangesSet to IntegersSubset, and CRSBuilder to IntegersSubsetMapping (allows to map individual subsets of integers to the BasicBlocks). Since in future these classes will founded on APInt, it will possible to use them in more generic ways. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157576 91177308-0d34-0410-b5e6-96231b3b80d8
