I think I misread the doxygen. verifyFunction & verifyModule return false if no errors are detected. However, my question now becomes why does the code produced by my transform pass verification, but it causes an assertion failure in the byte reader when it (the code produced by my transform) is passed to another invocation of opt?

I get a similar error when I try to disassemble a bytecode file generated by llvm-gcc released for llvm 1.9. Do I need to upgrade to a new llvm-gcc? Ryan M.

I am trying to use LLVM as a source to source C compiler. I use llvm-gcc to convert file.c->file.bc. Then I use opt to run my own compiler passes to convert file.bc->file.opt.bc. Then I use llc to convert file.opt.bc->file.opt.c. Now, I want to use normal gcc to compile file.opt.c into an executable. However, I'm getting the following errors: test.opt.c:89: warning:

I was able to correct this problem by checking out the latest version of llvm-gcc4 from svn and compiling it from source. One note, in order to get llvm-gcc4 to compile, I had to add #include "llvm/Analysis/LoopPass.h" to gcc/llvm-backend.cpp Ryan M.

Thanks for the help Reid! I frequently look at the online doxygen, but sometimes its difficult to determine the correct replacement when a method is removed from LLVM. In this particular case, I knew which new CallInst constructor to use, I just couldn't figure out the proper syntax. At any rate, I really appreciate your help!!

I didn't see anything on http://llvm.org/SVNMigration.html, but I'm assuming that llvm/projects has moved to llvm/examples. Is that correct? If so the documentation in http://llvm.org/docs/GettingStarted.html will need to be updated. In particular, the getting started doc talks about checking out llvm-test to llvm/projects. Also, I'm curious why the llvm/projects/sample

How do I acquire that version of DSA that you've updated to mainline cvs? Do I still check out llvm-poolalloc, or is there a way to only check out DSA?

Is there a conversion tool to convert llvm bytecode into c code? Regards, Ryan -- Ryan M. Lefever [217.333.7231] [http://www.ews.uiuc.edu/~lefever]

Thank you for the help. There seem to be several things in my makefiles that are messed up as a result of switching from the gcc3.4 front end to the gcc4 frontend. Is there any documentation listing the things that have changed? Thanks, Ryan Ryan M.

Ok, I think I figured it out. I talked to someone, and we figured out that when I make a call to printf with a constant string, I need to make a global variable and use getElementPtr to reference it. The modified call for accessing the printf is: /* m is Module*, f is Function*, i is Instruction* */ Constant* constStr = ConstantArray::get("test\n"); GlobalVariable* gv =

I am writing a pass where I need to make a function deceleration for printf. Below is the code I'm trying to use. ----- bool MyPass::runOnModule(Module &m) { vector<const Type*> args; args.push_back(PointerType::get(Type::SByteTy)); Function* f = m.getOrInsertFunction("printf", FunctionType::get(Type::IntTy, args, true)); ----- When I insert a call

I am still diagnosing the cause of the assertion failure and will submit a bug when I better understand the problem. Reid Spencer wrote: > Ryan, > > This looks like a bug.

I don't follow what you mean - gcc doesn't ignore const and llvm doesn't deviate from gcc nor from the relevant language standards. Note that if you declare a global as const that we do capture this in the ir - what specifically do you want? Please provide an example. -Chris http://nondot.org/sabre http://llvm.org On Aug 14, 2007, at 11:58 PM, "Ryan M. Lefever"

The reason I didn't use Xcode 2.4 is because I'm running OS X 10.3.9 (Panther). I have not upgraded the OS to 10.4. Xcode 2.4 requires OS X 10.4, according to Apple's website. Do you know otherwise? I think the highest Xcode I can get is 1.5. By the way what does FSF mean? I also tried compiling llvm with the gcc 3.3 that comes with OS X 10.3, and it gave the exact same error

I need to create a cast instruction that casts an sbyte* to another pointer type. Previously I was using the CastInst::createInferredCast() function to do that; however, that function has been removed. Which of the create() functions from CastInst should I use to do that? It seems like the obdvious answer should be createPointerCast(). However, the documentation for createPointerCast

I am trying to disassemble some bytecode using llvm-dis: llvm-dis -f -o llvmtest/sliceme2.cbc.ll llvmtest/sliceme2.cbc However, I am getting the following error. llvm-dis: Invalid bytecode signature: 464C457F (Vers=0, Pos=4) How do I go about figuring out what the problem is? llvmtest/sliceme2.cbc is newly compiled using the same version of llvm-gcc as llvm-dis. -- Ryan M.
