Hi, I want to use a function defined in c(++)-code from code generated by llvm. For this I use ExecutionEngine.addGlobalMapping(). I started with the JIT execution engine and everything worked, then I switched to the interpreter engine and it stopped working, but only if compiled on a Linux system. More precisely it works if I use llvm 3.8.1 + gcc (Linux) + JIT llvm 3.8.0 + mingw-gcc

Hola LLVMers, I'm looking to make use of the vectorization primitives in the Intel chip with the code we generate from LLVM and so I've started experimenting with it. What is the state of the machine code generated for vectors? In my tinkering, I seem to be getting some wonky machine instructions, but I'm most likely just doing something wrong and I'm hoping you can set me in

Hello, I found saw some strange behavior (to me) when converting constant arrays to strings. Consider the following example: std::string Text = "HelloWorld"; unsigned TextLengthBefore = Text.length(); ConstantArray *pArray = dyn_cast<ConstantArray>(llvm::ConstantArray::get(pModule->getContext(), Text, true)); unsigned NumElements = pArray->getNumOperands(); Text =

Hrm. This problem shouldn't be target specific. I am pretty sure prologue / epilogue inserter aligns stack correctly if there are stack objects with greater than default stack alignment requirement. Seems to be the initial alloca() instruction should specify 16 byte alignment? Evan On Jul 21, 2007, at 2:51 PM, Chris Lattner wrote: > On Fri, 20 Jul 2007, Chuck Rose III wrote:

I am fairly certain this is right. Chuck, can you do a quick experiment for me? Go back to your original code but make sure the alloca instruction specify 16-byte alignment. The code should work. If not, please file a bug. Thanks, Evan On Jul 24, 2007, at 1:58 PM, Evan Cheng wrote: > Hrm. This problem shouldn't be target specific. I am pretty sure > prologue / epilogue inserter

Hi, I haven't seen a response and I'm curious if I should submit a patch for this.
