Hi, I am trying to process the typeID from a type as follows: Type *T; if(T->isTokenTy()){ std::cout << "Token Type"; } /home/shehbaz/courses/ece1781/project/fslice/plugin/FSlice.cpp:147:14: error: ‘class llvm::Type’ has no member named ‘isTokenTy’ else if(T->isTokenTy()) ^ I am successfully able to do this for all other 20-25 types mentioned here:

Nadav, Arnold, et al., I have a number of loops that I would like us to be able to autovectorize (common, for example, in n-body inter-particle force kernels), and the problem is that they look like this: for (int i = 0; i < N; ++i) { if (r[i] > 0) v += m[i]*...; } where, as written, m[i] is not accessed unless the condition is true. The general problem (as is noted by the loop

Hi Hal, Yes, I agree that this is a problem that prevents vectorization in many loops. Another problem that we have is that sunk loads don’t preserve their control dependence properties. For example in the code below, if we sink the load into the branch then we can't vectorize the loop. x = A[i] if (cond) { sum += x; } I agree with you that checking the first and last element for each

Eg. < A , <int32, int32> , B , > <int32, bool , char *>>. I think the closest LLVM has is either Module::getIdentifiedStructTypes or the class it actually uses:

LLVM Newbie here. I have the following C++ program using namespace std; struct A{ int i; int j; }; int main() { struct A obj; obj.i = 10; obj.j = obj.i; return 0; } Using clang++, I can see that LLVM IR contains struct field as below %struct.A = type { i32, i32 } I would like to obtain the structure elements using LLVM Pass. I write the following program - that iterates

Hi All, I have just started using LLVM . i am facing a issue while using ilist container. Here is a struct with ilist container as its one element. typedef ilist<Instruction *> InstListType; struct list_node { int Impact; InstListType InstList; }; list_node

I think that the best way to move forward with the vectorization of this loop is to make progress on the vectorization pragmas. The LoopVectorizer is already prepared for handling pragmas and we just need to add the clang-side support. Is anyone planning to work on this ?

Hi, Can anyone tell me how to erase an instruction, (specially a load/store instruction) ? If I use Instr->eraseFromParent(), I get following error. Note the instruction does not have any use. opt: /home/chayan/llvm/llvm-2.6/include/llvm/ADT/ilist.h:218: llvm::ilist_iterator<NodeTy>& llvm::ilist_iterator<NodeTy>::operator++() [with NodeTy = llvm::Instruction]: Assertion

Hello, Thank you for your answer. If I want to use then I have error: ‘NodeTy* llvm::ilist_half_node<NodeTy>::getPrev() [with NodeTy = llvm::Instruction]’ is protected error: ‘llvm::ilist_half_node<llvm::Instruction>’ is not an accessible base of ‘llvm::Instruction’ Do you know any other method to access the previous instruction of a terminator instruction?

I don't see any method like hasPrevNode. It can be a weird problem because "current->getPrevNode()" is indicating to "current" itself (the problem appears for the BB with only one element)?

I solved by checking if(BB->size()>1) Thank you all for the help ! Now debugging the next segfault.

Hi all, I am in the process of developing a installer utility for ARM target which can compile any source files to ARM native executable. This installer utility should be present on target itself (whether this is feasible or not?). For achieving this i compiled llvm with clang for target. I copied the binaries to target and when it tried to compile a sample c code i am getting the following

I am using LLVM 2.6 and I have a question on the use of the BasicBlock::iterator to hoist loop invariant instructions to the loop preheader. When I process the instructions backward as shown in the following code, I got the following error right after the "hoist(I)" is done. Can anyone advise whether I am misusing BasicBlock::iterator? /opt/llvms/src/llvm_26/
