Hi, guys. I'm a newbie to LLVM and have a very simple question. Which instructions should I use (in terms of IRBuilder calls) to allocate an array of bytes in stack (alloca?), then to work with it (from a given offset) as with integer (bitcast?). I mean something like that: unsigned char var[8]; unsigned int offset = 3; int val = *(int*)(&var+offset); /* read */ *(int*)(&var+offset)

Hi Matthijs, Yes, I've turned off the link-time optimizations (otherwise it just propagates my constant vectors and immediate prints the result). :-) Here's essentially what I try to generate: void add(float z[4], float x[4], float y[4]) { z[0] = x[0] + y[0]; z[1] = x[1] + y[1]; z[2] = x[2] + y[2]; z[3] = x[3] + y[3]; } And here's part of the output from the online

llvm does not automatically vectorize your scalar code (as least for now). You have to write gcc generic vector code or use vector builtins.

Hi Evan, Please note that I'm not trying to compile from C code, I try to generate functions at run-time directly. I want to keep it target-independent too, so I can't use intrinsics either.

Hello, I'm trying to translate part of Java code in LLVM code. I have some problems with the "opaque type", I think because I did not understand how to use. So, the java code is: int[] ai; .... ai = new int[1]; I am using LLVM API in this way: //I create a pointer of Opaque type, because I don't know yet the array size! OpaqueType* ot = OpaqueType::get(); AllocaInst*

hi all please could u help me in these points 1- I have installed llvm-gcc 4.2 and llvm 2.8 with the synaptic package manager(ubuntu 10.10) every time i do this commande: llvm-gcc -O3 -emit-llvm hello.c -c -o hello.bc it shows to me i should install llvm-gcc4.5 when i have installed llvm-gcc 4.5 i get all the times a wrong bc file as output, because when i try to execute it with lli it says to me

We try to use llvm to translate and generate the native code in parallel with multi-thread. But some various bugs will be triggered. We run the following code in multithread environment: ################## BasicBlock::Create(_CTX(), "dispatch", cpu->cur_func, 0); BranchInst::Create(bb_start, label_entry); cpu->exec_engine->getPointerToFunction ##################3 And cpu
