I would like to instrument certain function calls with a function call of my own that takes some of the same arguments. For example, I would like to instrument calls to free with some function foo, so the C code would look like: foo(myarg1, myarg2, ptr); free(ptr); The problem occurs when I grab the arg from the free function and try to pass it to foo... if (isCallToFree(&I)) { Value*

...on, not the arguments of the function being called. So if you're sure it's a call or invoke (not a 'free' instruction), try something like this: #include "llvm/Support/CallSite.h" // ... CallSite CS(&I); CallSite::arg_iterator ait = CS.arg_begin(), aend = CS.arg_end(); > if (ait) { You want if (ait != aend) { here. > P = &(*ait); > } > createCallInst(mem_fcall, &I, 3, getOpcodeValue(I), > getInstrIDValue(), P); > } > } > > createCallInst is my own...

can we assume that for(Function::aiterator I = F.abegin(); E = F.aend(); I!=E; ++I) { .... } or Argument *FA = &F.afront(); do { FA = FA->getNext(); .... } while (FA != &F.aback()); would iterate over function "F" formal parameters in order? All the tests I've run so far indicate so, but unless it is guaranteed, I don...

Hi, I am trying to insert a Loop IR into the existed bytecode file. insertion part by C code, char *p[n]; // pointer array for storing the address of strings int i; for(i=0;i<n;i++){ (p[i])[2] = (p[i])[2] ^ 0x27; } My questions are 1. for local variable 'char *p[n]' , it is represented by IR as alloca ...., so could I insert local variable (pointer array) directly as same way

Hi LLVMers, the example attached I have used to prove that JIT and some visible optimizations are really invoked. Proved OK. I got 30% speed-up in comparison to gcc 3.3.3 on my Athlon XP 1500. Nice. P.S. guys, no fears, I don't plan to flood the cvs repository with my "brilliant" examples ;) --- Valery A.Khamenya -------------- next part -------------- An

Reid Spencer, thank you for your quick responce, finally i got to my PC at home.

Valery, Attached are three files: "valery.cpp" which contains your original, "reid.cpp" which contains corrections to most of the FIXME items and "diffs" which shows the differences between them. The differences should be instructive on what to do. You were really, really close .. just a few details changing. The code in "reid.cpp" compiles but I
