I hope this is the correct forum in which to ask this question. Currently I am writing code meant to compile with LLVM 3.0. I am trying to figure out, using the C++ API, how to create a constant static struct, or the equivalent. Since I am copying data from existing C structs, I am currently I am using a ConstantArray global variable, and then pointer casting it to the appropriate type when I

Hi All, Is there a way to convert a const char * to a Value type? Thanks. George -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20110517/0077b44c/attachment.html>

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

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 =

...at runtime, and so can't use a const char * from compile time. You need to make the string visible in the compiled image, and use that as the argument. A string is an array of 8-bit integers, so you need to create a ConstantArray. Value *v = ConstantArray::get(Context, callee->getName(), /*AddNull=*/true); Cheers, James -----Original Message----- From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of Dmitry N.

Hi, I'm trying to replace function call with call to wrapper(function_name, num_args, ...), where varargs hold args of original call. Function* launch = Function::Create( TypeBuilder<int(const char*, int, ...), false>::get(context), GlobalValue::ExternalLinkage, "kernelgen_launch_", m2); { CallInst* call = dyn_cast<CallInst>(cast<Value>(I)); if

Um... That's exactly what the example above demonstrates. But maybe I did not explain my problem well enough. If I have a type like, for example: { i32, [ 4 x i8 ] } How can I create a constant of this type like this: { i32 0x1ffff, [ i8 0, i8 4, i8 10, i8 8 ] } from the C++ A...
