Hi, I would like to give a quick update on what my current design and implementation go like. Basically, the `FunctionToLoopPassAdaptor` is now modified to a generic version `FunctionToLoopUnitPassAdaptor`, which allows re-using the existing codes to implement `FunctionToLoopNestPassAdaptor`, with the help of additional metadata associated with `Loop` and `LoopNest`. Both

Hi, Thanks for your help! I've checked the sources that you mentioned. Currently, I think that I would need to implement a FunctionToLoopNestPassAdaptor which is essentially the same as the FunctionToLoopPassAdaptor but operates only on LI.getTopLevelLoops(). We might also need a LNPMUpdater (LoopNestPassManagerUpdater) which disallows adding inner-loops back into the pipeline, and

I notice that there's a lot of inconsistency in the various LLVM classes with respect to convenience methods. Here's some examples: For creating GEPS, IRBuilder has: CreateGEP (2 overloads) CreateInBoundsGEP (2 overloads) CreateConstGEP1_32 CreateConstInBoundsGEP1_32 CreateConstGEP2_32 CreateConstInBoundsGEP2_32 CreateConstGEP1_64 CreateConstInBoundsGEP1_64

Hi Dominic, +//===-- llvm/Support/IRBuilder.h - Builder for LLVM Instrs -----*- C++ -*-===// is this line the right length? It seems shorter than the similar lines below like this one: +//===----------------------------------------------------------------------===// + GetElementPtrInst *CreateStructGEP(Value *Ptr, unsigned Idx, + const char *Name =

Sure, it is the Rodinia 2.4 Hotspot benchmark OpenCL kernel (not my kernel), with the addition of my struct as the last argument in the kernel function. //------- kernel file start ------------------------------- #define BLOCK_SIZE 16 //dlowell's type #define BUFFER_LEN 0x100000 typedef struct RB{ unsigned int x; unsigned int y; int z[BUFFER_LEN]; unsigned int xx[BUFFER_LEN];

Hi Sarath, It would have really helped if you had removed the commented out code and inlined the calls to your homemade helper functions before sending it... You are doing this, in LLVM IR: %0 = getelementptr %Value* %firstArg, i32 0 ; i8** %1 = load i8** %0 ; i8* %2 = bitcast i8* %1 to i64* %3 = getelementptr %Value* %secondArg, i32 0 ; i8** %4 = load i8** %3; i8* %5 = bitcast i8* %4 to i64*

If I do M.dump(), at the top of the output I have: %struct.RB = type opaque Further down I have: @.str18 = internal addrspace(2) constant [13 x i8] c"RB_t*\00" However nowhere does it dump the full struct type when I call "M.dump()". I have it explicitly defined above the kernel in the kernel file, but LLVM doesn't seem to pick it up. Opaque is a placeholder until it

Hi all, I was trying to implement an obfuscation tool for C-code on the basis of LLVM. I got a prototype of the simple obfuscation transformation which converting control flow graph to something like a state machine. I am not sure I will have time to work on extending further this tool with new transformations like opaque predicates and decided to put here source code I have by now with hope

Yeah, that's the fault...got the answer...... Thanks James for the help... Struggling with this for so many days.......

Does getelementptr have a counterpart function which unindexes a pointer? In particular, I'm using CreateStructGEP from the builder and want to get back to the struct pointer from a member pointer. fptr = b.CreateStructGEP( sptr, 2 ); //I want to do this sptr = b.CreateUnStructGEP( fptr, sptr_type, 2 ); I know I can calculate the offsets on my own, but it'd be nice to not have to since

cB->getType()->getPointerElementType()->dump(); gives: %struct.RB = type opaque2189 x_idx = builder.CreateStructGEP(cB, 0); cB->dump() gives: %struct.RB addrspace(1)* %cB $1 = void //To undo confusion, the last cB is the function arg name. For this example I unfortunately chose the same name for my argument Value* as the argument name. //Also one correction. I am running

Hello, I have implemented a pass to count total number of instructions in LLVM 8.0. Its source code is attached here. The pass runs fine with LLVM 4.0. But with LLVM 8.0 following error is shown; $ $LLVMopt_BIN/opt -load $LLVM_SO/LLVMStatic-Info.so -one output-simple.bc WARNING: You're attempting to print out a bitcode file. This is inadvisable as it may cause display problems. If you REALLY

Hi, I'm gettign an assertion fail/crash in X86FrameLowering::GetFrameIndexReference when compiling the following bitcode: https://gist.github.com/carlokok/868cddebeb9acc8ccbac6253de0480b0 I tried removing the llvm.frameaddres calls but that's not it, where can I start looking for what my mistake here is? Code seems to verify just fine. ; #0 0x00e1afe8

Hi all, I'm trying to play with patchoint (with MCJIT and VMKit) and I don't understand something. I generate this call for my first patch point. Basically, I want to call f(0). %5 = call i64 (i64, i32, i8*, i32, ...)* @llvm.experimental.patchpoint.i64( i64 42, ;; patch point id is 42 i32 0, ;; 0 bytes for the padding i8* bitcast (i32 (i32)* @f to i8*), ;; my function f i32 1,

Hi, I was trying to create a new *Store* instruction and inserting it to LLVM IR (.ll) file. I found the following constructor in LLVM Manual: StoreInst::StoreInst <http://llvm.org/docs/doxygen/html/classllvm_1_1StoreInst.html#aa2a72f9a51b317f5b4ab8695adf59025> (Value <http://llvm.org/docs/doxygen/html/classllvm_1_1Value.html> * Val, Value

I think r262546 introduced the assumption that allocas are used exactly once with catchpad. It seems easy to fix, though.
