If you remove all the 'static's from the member functions, it'd work more like IRBuilder. It would also allow you to take the LLVMContext& as a constructor parameter, so that methods like this: On Fri, Feb 4, 2011 at 6:57 PM, Talin <viridia at gmail.com> wrote: >   /// GetStruct - return a constant struct given a context and a vector >   /// of elements. >   static

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*

Hi, Just to report that when I tried to compile some code with a NoFolder given as template arg to my IRBuilder, the compiler complained with: In file included from lang_3-llvm.cxx:33: /usr/lib/llvm-2.8/include/llvm/Support/IRBuilder.h: In member function ‘llvm::Value* llvm::IRBuilder<preserveNames, T, Inserter>::CreateFNeg (llvm::Value*, const llvm::Twine&) [with bool preserveNames =

Seeing as it's completely broken (it doesn't insert the created instructions into the relevant basic block) that's probably best... :( (It's also missing most of the casting operations, by the way)

Hi, I'm trying to define a mutable variable, outside functions. The code below is trying to evaluate an expression much like "x = 1" at the module level in Python. It appears that when it tries to JIT the function there is an error because there is no storage allocated for 'x'. How do I do that? thanks, Rob ----- dumped IR ----- ; ModuleID = 'repl-module' %0 =
