similar to: [LLVMdev] ExtractBasicBlock() on block that ends with invoke or unreachable triggers assert() in llc

All, I'm looking at the lowerinvoke pass as a starting point for getting SJLJ based exception handling working on ARM, but am having some troubles with it. When I run a simple testcase (attached) through llc and specify -enable-correct-eh-support, llc asserts on me. It appears there's been some bitrot somewhere. SelectDAGBuild and SelectionDAGISel cooperate to track landing pads

I'm getting a very stubborn assertion failure that I don't understand. After I insert a call to an externally defined function into an invoked function, llc spits out the following assertion failure when I compile the bytecode: llc: SelectionDAGISel.cpp:4912: virtual bool llvm::SelectionDAGISel::runOnFunction(llvm::Function&): Assertion `FuncInfo.CatchInfoFound.size() ==

Hi, My transformation phase inserts an if-the-else construct into a BB. If that BB contains llvm.eh.exception, I get an Assertion at some later point: lib/CodeGen/SelectionDAG/FunctionLoweringInfo.cpp:212: void llvm::FunctionLoweringInfo::clear(): Assertion `CatchInfoFound.size() == CatchInfoLost.size() && "Not all catch info was assigned to a landing pad!"' failed. Is

Hi, I'm trying to compile an llvm program which makes use of exception handling. While compiling the code with llc i get the following assertion failure llc: FunctionLoweringInfo.cpp:163: void llvm::FunctionLoweringInfo::clear(): Assertion `CatchInfoFound.size() == CatchInfoLost.size() && "Not all catch info was assigned to a landing pad!"' failed. 0 llc

Hi, In SelectionDAGISel::SelectAllBasicBlocks if (TM.Options.EnableFastISel) FastIS = TLI->createFastISel(*FuncInfo, LibInfo); followed by if (!FastIS) { LowerArguments(Fn); } else { The above implies that implementing FastIS is optional. In contrast to that, testing whether FastIS is actually been used is done by testing if TM.Options.EnableFastISel is set. For example

Thanks for all your help so far. My problem is that what I have are the pool descriptors, which I by traversing the uses of poolinit and accessing the first argument of each call. I need to find the DSNode (in the original function) to which this pool descriptor corresponds. The rub is that this pool descriptor of course does not exist except in the clone. If I call getFuncInfo(), I get a

This commit will let our unconditional branch instruction not be deleted when its successor is the nature layout and its basic block's instruction only one instruction.

Hi Patrick, That's right. DSNodes are coupled to the original function. For function clones, you first need to get the original function, and then use the DSNode from that function. FuncInfo contains the information if a function is a clone and what the original function is. If you want to find the corresponding DSNode for some instruction, you must call PA::FuncInfo::MapValueToOriginal(

I've just looked at my checkout of 3.6 and it looks like the fix wasn't merged. I don't have the revision number for the fix to hand but in lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp, this: MatchFilterBB = (!FilterDAGBasicBlockName.empty() && FilterDAGBasicBlockName == FuncInfo->MBB->getBasicBlock()->getName().str());

Daniel, Ok, thanks. Simple fix. We'll just make correction in local copy for now, one less thing to port later :) Thanks.

Hi, It's changed a few times over the last year. I believe xdg-open spawns whichever application your desktop environment would use to open the file so you should be able to tell it to use dotty.

Harmen, your suggestion of inverting the mapping almost worked (and Andrew was correct that the function I need is the same as the one in which poolinit appears). Unfortunately, it appears that this mapping only considers the original function and not any of its clones. Since the pool descriptor in question may very well only exist in a clone, I can't use this. Is there another way?

You might want to have a look at PoolAllocate.h. Per function, a PA::FuncInfo structure keeps track of all DSNodes that should be pool allocated. ArgNodes contains pool arguments, NodesToPA contains nodes that are locally pool allocated and thus initialized using poolinit. PoolDescriptors contains a mapping from DSNodes to pool descriptors, and you could easily invert this mapping. Finding a

Hello, I did a little experiment modifying LLVM to be able to use alias-analysis information in scheduling so that independent memory operations may be reordered. Attached is a patch which implements this. I copied some routines from DAGCombiner.cpp for using SDOperands with alias queries; it should probably be factored out somewhere so the code can be shared. I reorganized

First, is the possible lack of conformance with the ABI you state, which I can't comment since I don't know that ABI very well.
