Hi, Sorry for bothering you guys again. I got problem when I am trying to recover the Global Variable Initial value. What I did is like the following ConstantArray *Cstr = dyn_cast<ConstantArray>(gI->getInitializer()); // the above instruction enable me to get the content of initial string of global variable, like char a[10] ="test global"; And then I make some change for

Thanks Chris, but the method you mentioned is not what I want. Maybe I didn't make it clear. As you said, /runtime/libprofile is runtime library for the following function. llvm_start_func_profiling llvm_start_block_profiling llvm_start_basic_block_tracing llvm_trace_basic_block And those above functions can be inserted into basic block etc for getting profile. However, those

Hi, I got a problem when I am trying to insert a call function with pointer arguments. The function C proto-type is the following, void stat_func(char *); >ConstantArray *Cstr = dyn_cast<ConstantArray>(gI->getInitializer()); ...... >Function *exFunc = M->getOrInsertFunction("stat_func", Type::VoidTy, PointerType::get(Type::SByteTy),0); >std::vector<Value*>

Thanks for your reply. After I change Cstr to gI, it compiled successfully. Thanks again. Another question is for constructing getelementpt. // C code char gStrA[10] = "test str"; // here is Global variable,gStrA and initializer "test str" char gStrB[10]= "test str2"; main(){ int = i; char *pGVars[20]; // here, the pGVar is for storing the address of each

Evening, I was writing some code that tried to insert calls to the llvm.annotation intrinsic function, which has a signature of (i32, i8*, i8*, i32). The code is below. void addAnnotation( BasicBlock *block, Function *F) { string foo = "foo"; string bar = "barr"; Type *charTy = Type::getInt8Ty(block->getContext()); ArrayType *s1Ty =

I've been creating some R tools that manipulate objective functions for optimization. In so doing, I create a character string with R code, and then want to have it in my workspace. Currently -- and this works fine -- I write the code out, then use source() to bring it in again. Example: cstr<-"jack<-function(x){\n cat(\"Silly x:\")\n print(x) \n }\n" write(cstr,

Sorry for emailing both group. As I will have a constant array of BlockAddress, what type I should use in Constant Array for its ArrayType declaration? I am creating the list in following way: unsigned int nBr = fit->second.size(); llvm::Constant *listBA[nBr]; unsigned int Idx = 0; for (std::set<llvm::BasicBlock *>::iterator it = fit->second.begin(); it != fit->second.end(); ++it)

Heyho, Recently I tried out the ORCv2 JIT, especially the LLJIT. I gotta say, that I really like the new interface and the way you use it! However there is one thing I'm missing. I wrote a small bit code file, which should force having a global constructor. int wuff(); __declspec(noinline) int miau() { printf("Huhuhu"); return wuff(); } const int x = miau(); When I

Hey Duncan, Thanks! I figured out this piece of code finally: Value *gep = call->getArgOperand(0); if ( ConstantExpr *pCE = dyn_cast<ConstantExpr>(gep) ) { Value *firstop = pCE->getOperand(0); if (GlobalVariable *GV = dyn_cast<GlobalVariable>(firstop)){ Constant *v = GV->getInitializer(); if

OK here's a new version of the patch - and the unions.ll test actually passes :) On Mon, Jan 18, 2010 at 1:40 PM, Chris Lattner <clattner at apple.com> wrote: > > On Jan 16, 2010, at 11:15 AM, Talin wrote: > > OK here's the patch for real this time :) >> >> On Fri, Jan 15, 2010 at 4:36 PM, Talin <viridia at gmail.com> wrote: >> Here's a work

excuse me for bother you again . a little supplement Constant* c = findValue(m,"E1$entry"); Constant* c2 = findValue(m,"E1$str"); I can get string object from c2 string s = cast<ConstantArray>(c2)->getAsString(); but it is not applicable for c string s= cast<ConstantArray>(c)->getAsString(); // Assert Fail because c is ConstantExpr::GetElementPtr

I've made all the suggested changes - however, I'm having a bit of problem running the tests. I started "make check" and several hours later it had only made it through about 1/3 of the tests. I'm not sure what the deal is. On Mon, Jan 18, 2010 at 1:40 PM, Chris Lattner <clattner at apple.com> wrote: > > On Jan 16, 2010, at 11:15 AM, Talin wrote: > > OK

Hi, I'm trying to run the pool allocation pass through opt, and I'm running into problems. It segfaults frequently; for example, it does this when the input is a simple Hello World program: [simmon12 at apoc testcases]$ opt -load /home/vadve/simmon12/llvm/llvm/projects/llvm-poolalloc/Debug/lib/libLLVMDataStructure.so -load

Hi, all: I want to check small files' property(such as date, path, and so on) frequently. The files are stored in netwrok driver and their sizes vary from 2KB to 5KB. I found that Windows 2K outperform Linux/Samba very much after I campared the bench results. I am very confused about it and who can explain it? The computers' configurations are as follows: 1.
