similar to: [LLVMdev] Insert a function call in the code

Thank you for your help I found the problem, as hook() is a no paramter function,so for(Function::arg_iterator i = hook->arg_begin(), e = hook->arg_end(); i != e; ++i) { Args.push_back(i); /////////////Wong } we can add a call by Instruction *newInst = CallInst::Create(hook,

Yeh, I eventually figured that out. Thanks for responding though.

Hi Alastair, Thank you so much for the information on the tools. Actually, I need to analyze which sections of code are prone to misses and mis predicts, and would have to eventually instrument the code. I was able to instrument and call an external function, but faced an issue while passing an argument to the function. I am following EdgeProfiling.cpp but couldn't figure out the problem.

Hello all; So my goal is to insert some (self-written) function calls in the LLVM IR. I can achieve it with a ModulePass and using the getOrInsertFunction() call. For a ModulePass I follow the steps- 1. Compile the code (in which call instructions are to be inserted) to LLVM IR 2. Compile the file (which contains the *called* external function ) to LLVM IR 3. Link them together and run the

Hi, I tried passing the array directly using and changing the getorInsertFunction accordingly but this didn't work. It fails with Assertion `(i >= FTy->getNumParams() || FTy->getParamType(i) == Args[i]->getType()) && "Calling a function with a bad signature!"' failed. hookFunc = M.getOrInsertFunction("hook", Type::getVoidTy(M.getContext()),

Hi, @Alastair: Thanks a bunch for explaining this so well. I was able to write a simple profiler, and run it. I need to profile the code for branches (branch mis predicts simulation), load/store instructions (for cache hits/miss rate), and a couple of other things and therefore, would need to instrument the code. However, I would like to know if writing the output to a file would increase the

Hi Silky, Sorry for the slow reply. You probably already fixed this, but just in case I'll reply anyway.

Hi all, I am new to LLVM, and I am learning how to use LLVM for profiling. I need to pass an array to an external method, and insert a call instruction to the method in the code. After reading a few source files, I've tried using GetElementPtrInst to pass an array, but it fails at llvm::GetElementPtrInst::hasAllZeroIndices() const + 0 std::vector<Value*> Args(1);

Hi Nick and Bill, Attached is a new version of the patch that checks against cur_buffer_size. This works with the cases I've been using but again I haven't run the official tests on this change.

The tripplite driver was developed on a machine with a reliable serial connection, and inherited the assumption that the serial line connection would not drop, reorder, or fail character read and writes. This patch adds significantly improved failure mode handling and also does basic checks of data validity. There's also a few minor cleanups/beautification. I've tested this code on my

Hi Nick, Thanks for looking over my patch. I'd be happy to add the compare against cur_buffer_size. I'll try to write up such a change today and then send a new patch to the list.

Bill, could you take a look at this? I don't have a checkout of compiler-rt that builds. It seems obviously-correct to me, but I wish it did a compare against cur_buffer_size to make sure it's in range.

Hi, I want to insert a function with a void type parameter, for example: int foo(void); OI declared fcall2 = M.getOrInsertFunction("foo", IntegerType::get(M.getContext(), 32), Type::getVoidTy(M.getContext())); then the question is how to get the void type value to make the CallInst inserted sucessfully? (what should be ********) CallInst::Create(fcall2, ******,

Look at "Builtin\system" which is also "NT Authority\System. Ahem, clearly every machine (workstation, server; i suppose also the domain) have a SYSTEM account, but they

Hi, I've been seeing a crash in llvm_gcda_emit_arcs() on x86_64. The crash occurs executing a movdqa instruction with an unaligned src address. The attached patch to the compiler-rt project fixes the problem by using memcpy() to read data from the write_buffer[] in GCDAProfiling.c. This is my first patch submission to llvm so please let me know if I've missed any steps. I'm not on

Hello every, I am new to LLVM, using it to create a system Now I have a problem code below: int main(int argc, char **argv) { symbolic(2);//symbolic(int a) sleep(1,2);//sleep(int a, int b) } two definations of sleep int sleep(int a, int b) { return a+b; } int sleep(int a, int b) { return a-b; } can I choose different sleep() by the result of symbolic(), if symbolic(5)

The code that I have written to get the function type is: const std::vector<Type *> ParamTys; ParamTys.push_back(IntegerType::getInt32Ty(Context)); ParamTys.push_back(IntegerType::getInt32Ty(Context)); ParamTys.push_back(IntegerType::getInt32Ty(Context)); ParamTys.push_back(PointerType::get(Type::getVoidTy(Context), 0)); ParamTys.push_back(PointerType::get(Type::getVoidTy(Context), 0));
