2012-10-11Remove unnecessary classof()'sSean Silva
isa<> et al. automatically infer when the cast is an upcast (including a self-cast), so these are no longer necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165767 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-11Remove buggy classof().Sean Silva
This classof() is effectively saying that a MachineCodeEmitter "is-a" JITEmitter, but JITEmitter is in fact a descendant of MachineCodeEmitter, so this is not semantically correct. Consequently, none of the assertions that rely on these classof() actualy check anything. Remove the RTTI (which didn't actually check anything) and use static_cast<> instead. Post-Mortem Bug Analysis ======================== Cause of the bug ---------------- r55022 appears to be the source of the classof() and assertions removed by this commit. It aimed at removing some dynamic_cast<> that were solely in the assertions. A typical diff hunk from that commit looked like: - assert(dynamic_cast<JITEmitter*>(MCE) && "Unexpected MCE?"); - JITEmitter *JE = static_cast<JITEmitter*>(getCodeEmitter()); + assert(isa<JITEmitter>(MCE) && "Unexpected MCE?"); + JITEmitter *JE = cast<JITEmitter>(getCodeEmitter()); Hence, the source of the bug then seems to be an attempt to replace dynamic_cast<> with LLVM-style RTTI without properly setting up the class hierarchy for LLVM-style RTTI. The bug therefore appears to be simply a "thinko". What initially indicated the presence of the bug ------------------------------------------------ After implementing automatic upcasting for isa<>, classof() functions of the form static bool classof(const Foo *) { return true; } were removed, since they only serve the purpose of optimizing statically-OK upcasts. A subsequent recompilation triggered a build failure on the isa<> tests within the removed asserts, since the automatic upcasting (correctly) failed to substitute this classof(). Key to pinning down the root cause of the bug --------------------------------------------- After being alerted to the presence of the bug, some thought about the semantics which were being asserted by the buggy classof() revealed that it was incorrect. How the bug could have been prevented ------------------------------------- This bug could have been prevented by better documentation for how to set up LLVM-style RTTI. This should be solved by the recently added documentation HowToSetUpLLVMStyleRTTI. However, this bug suggests that the documentation should clearly explain the contract that classof() must fulfill. The HowToSetUpLLVMStyleRTTI already explains this contract, but it is a little tucked away. A future patch will expand that explanation and make it more prominent. There does not appear to be a simple way to have the compiler prevent this bug, since fundamentally it boiled down to a spurious classof() where the programmer made an erroneous statement about the conversion. This suggests that perhaps the interface to LLVM-style RTTI of classof() is not the best. There is already some evidence for this, since in a number of places Clang has classof() forward to classofKind(Kind K) which evaluates the cast in terms of just the Kind. This could probably be generalized to simply a `static const Kind MyKind;` field in leaf classes and `static const Kind firstMyKind, lastMyKind;` for non-leaf classes, and have the rest of the work be done inside Casting.h, assuming that the Kind enum is laid out in a preorder traversal of the inheritance tree. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165764 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-01PR1255: case ranges.Stepan Dyatkovskiy
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

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
