* Extend the IL for selecting TLS models (PR9788)Hans Wennborg2012-06-234-6/+71
| | | | | | | | | | | | | | | This allows the user/front-end to specify a model that is better than what LLVM would choose by default. For example, a variable might be declared as @x = thread_local(initialexec) global i32 42 if it will not be used in a shared library that is dlopen'ed. If the specified model isn't supported by the target, or if LLVM can make a better choice, a different model may be used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159077 91177308-0d34-0410-b5e6-96231b3b80d8

* Now that Reassociate's LinearizeExprTree can look through arbitrary expressionDuncan Sands2012-06-122-0/+43
| | | | | | | | | | | | | | | | | | topologies, it is quite possible for a leaf node to have huge multiplicity, for example: x0 = x*x, x1 = x0*x0, x2 = x1*x1, ... rapidly gives a value which is x raised to a vast power (the multiplicity, or weight, of x). This patch fixes the computation of weights by correctly computing them no matter how big they are, rather than just overflowing and getting a wrong value. It turns out that the weight for a value never needs more bits to represent than the value itself, so it is enough to represent weights as APInts of the same bitwidth and do the right overflow-avoiding dance steps when computing weights. As a side-effect it reduces the number of multiplies needed in some cases of large powers. While there, in view of external uses (eg by the vectorizer) I made LinearizeExprTree static, pushing the rank computation out into users. This is progress towards fixing PR13021. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158358 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | IntItem cleanup. IntItemBase, IntItemConstantIntImp and IntItem merged into IntItem. All arithmetic operators was propogated from APInt. Also added comparison operators <,>,<=,>=. Currently you will find set of macros that propogates operators from APInt to IntItem in the beginning of IntegerSubset. Note that THESE MACROS WILL REMOVED after all passes will case-ranges compatible. Also note that these macros much smaller pain that something like this: if (V->getValue().ugt(AnotherV->getValue()) { ... } These changes made IntItem full featured integer object. It allows to make IntegerSubset class generic (move out all ConstantInt references inside and add unit-tests) in next commits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157810 91177308-0d34-0410-b5e6-96231b3b80d8

* PR1255: Case RangesStepan Dyatkovskiy2012-05-282-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
