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.

OK, I noticed a few problems with my previous email, so I will boil the question down: What I want to do is compile for x86 and ia64 from darwin. I also want to load my own passes into opt and llc. Should I be using llvmc at all here, or should I be doing something like llvmgcc -> gccas -> opt -> llc ? I've given up on the filetype=obj argument, so now the problem is that llc is

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 ---------------------------------

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, I have a hopefully quick question. I'm writing a Pass that needs to see a whole module at a time and keep some state, so I subclassed Pass. However, I want to be able to see the Loops in each Function. Roughly, here's what I want: virtual bool run(Module &M){ // do stuff... for (Module::iterator I = M.begin(), E = M.end(); I != E; ++I){ if(! I->isExternal())

Hi, i used CVS to checkout the source of llvm and llvm-gcc, compiled and built them on my machine successfully. i tried a c-language hello program, it was OK. But when i tried a c++-language hello program, i got: ~/project/llvm/examples$ llvm-g++ t3.cc -o t3 gccld: /developer/zsth/project/llvm/src/llvm/lib/Analysis/IPA/CallGraph.cpp:277: void

Dear LLVM guys, I've solved my problem with the passes, and compiled my first code using the new register allocator! Debugging was quite easy, using gdb. The problem was that I was forgetting to initialize the array that records the physical registers ever used (MachineFunction::UsedPhysRegs). This is a very minor thing, but I would suggest asserting that the vector has been initialized

Yes. The general approach is to use llvm-as, llvm-dis, opt and llvm-link to work with the bytecode. You can also use gccld and gccas to run some canned
