[LLVMdev] StructReturnToPointer in poolalloc failing with LLVM 3.4 (original) (raw)

Hi,

I've been happily using DSA in a project of mine for quite a while now, and recently I noticed that the functionality of StructReturnToPointer could be useful to me as well.

So I tried using it on a simple example, but I keep getting the following exception:

smack: /home/zvonimir/projects/smack-project/llvm/src/lib/IR/Attributes.cpp:912: unsigned int llvm::AttributeSet::getSlotIndex(unsigned int) const: Assertion `pImpl && Slot < pImpl->getNumAttributes() && "Slot # out of range!"' failed. 0 smack 0x0000000000a38982 llvm::sys::PrintStackTrace(_IO_FILE*) + 34 1 smack 0x0000000000a37d69 2 libpthread.so.0 0x00007fc770d81cb0 3 libc.so.6 0x00007fc76fdab425 gsignal + 53 4 libc.so.6 0x00007fc76fdaeb8b abort + 379 5 libc.so.6 0x00007fc76fda40ee 6 libc.so.6 0x00007fc76fda4192 7 smack 0x000000000090164f 8 smack 0x000000000099a984 llvm::Argument::addAttr(llvm::AttributeSet) + 36 9 smack 0x000000000050f294 llvm::StructRet::runOnModule(llvm::Module&) + 2180 10 smack 0x00000000009c2e1f llvm::legacy::PassManagerImpl::run(llvm::Module&) + 927 11 smack 0x000000000048d448 main + 840 12 libc.so.6 0x00007fc76fd9676d __libc_start_main + 237

Basically, there is a problem with the following piece of code, and I suspect it might be due to upgrading to LLVM 3.4: ValueToValueMapTy ValueMap; Function::arg_iterator NI = NF->arg_begin(); NI->setName("ret"); ++NI; for (Function::arg_iterator II = F->arg_begin(); II != F->arg_end(); ++II, ++NI) { ValueMap[II] = NI; NI->setName(II->getName()); NI->addAttr(F->getAttributes().getParamAttributes(II->getArgNo() + 1)); }

I've tried to fix this, but no luck so far, and so help would be great appreciated.

Thanks!
