Rematerialization is handled by LiveRangeEdit now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157974 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-05Stop using LiveIntervals::isReMaterializable().Jakob Stoklund Olesen
It is an old function that does a lot more than required by CalcSpillWeights, which was the only remaining caller. The isRematerializable() function never actually sets the isLoad argument, so don't try to compute that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157973 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-01Switch all register list clients to the new MC*Iterator interface.Jakob Stoklund Olesen
No functional change intended. Sorry for the churn. The iterator classes are supposed to help avoid giant commits like this one in the future. The TableGen-produced register lists are getting quite large, and it may be necessary to change the table representation. This makes it possible to do so without changing all clients (again). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157854 91177308-0d34-0410-b5e6-96231b3b80d8

IntegersSubset devided into IntegersSubsetGeneric and into IntegersSubset itself. The first has no references to ConstantInt and works with IntItem only. IntegersSubsetMapping also made generic.

2012-05-30Prioritize smaller register classes for urgent evictions.Jakob Stoklund Olesen
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

2012-05-28PR1255: Case RangesStepan Dyatkovskiy
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

them by using edge weights. SimplifyCFG tends to form a lot of 2-3 case switches when merging branches. Move the most likely condition to the front so it is checked first and the others can be skipped. This is currently not as effective as it could be because SimplifyCFG destroys profiling metadata when merging branches and switches. Merging branch weight metadata is tricky though. This code touches at most 3 cases so I didn't use a proper sorting algorithm. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157521 91177308-0d34-0410-b5e6-96231b3b80d8
