Right now, addPassesToEmitFile requires a FunctionPassManager. If I'm working with code that uses a plain PassManager and want it to generate code, are there any options better than doing this: /** * Wrapper class to run a FunctionPassManager as a ModulePass so that it * can be added to a plain PassManager. */ class FunctionPassManagerModulePass : public ModulePass { FunctionPassManager

The patch below basically hammers out some ideas as to where I'd like to take the passmanager in LLVM. I've tried thinking things through, but I'm still a n00b, so some criticism would be more than welcome. =) Starting from line 191 down. If you're wondering why I created a patch, well that's because I found thinking in passmanagert.h the most productive. -- Regards.

Function pass manager itself is a module level pass.

Hi, I have been trying to randomize blocks in a program and modified "BasicBlockPlacement.cpp" for the purpose but getting segmentation fault.I am not able to determine the problem.Can anyone please decrypt these error messages or suggest what might be the possible cause of failure? -----------------------------------------------------------------------------------------------------

The various intrinsic assert/crashes should all be fixed on mainline CVS (they are PR733, which I just fixed). The only ones that I'm wary of are: XPASS: /proj/llvm/build/../llvm/test/Regression/CFrontend/2004-02-20- StaticRedeclare.c.tr FAIL: /proj/llvm/build/../llvm/test/Regression/CFrontend/2005-12-04- DeclarationLineNumbers.c: In the former case, I would guess that the test isn't

I just updated again (both llvm and llvm-gcc). The only thing that changed was: P test/Regression/CFrontend/2005-12-04-DeclarationLineNumbers.c The regression test below was done *with* your llvm-gcc changes to llvm- expand.c. I don't know what the failures are all about, but I will try it again. If its the same, I'll let you know. Reid. On Thu, 2006-04-13 at 16:20 -0500, Chris Lattner

Hi, Thank you for your answer. But let me get it straight, when i compile code with the llvm compiler, and my basic block pass is being processed, other passes are concurrently being processed ?

Dear LLVM guys, I am getting an error with my pass implementation, and I cannot figure it out. Basically, I've implemented part of a register allocation algorithm, but I am having problems to set the passes correctly. For instance, for this program below, the following error message is produced: .c ----------------------| .bc ---------------------------------

You will probably need to write code that does this for you. One place to put the code would be in the doInitialization() method of the BasicBlockPass that you're writing. However, I'm not sure if the count would be
