similar to: [LLVMdev] Extract Loop Failing

It looks like this problem only exists on nested loops, ideas?

Is it not a good idea to try and extract loops that have multiple exits?

How do you expect people to be able to tell you if you are using it properly if they can't see how you are using it?

Dear sir or madam, I am a 4-th year student at Yerevan State University, Armenia; and I am studying LLVM in order to write my Bachelor thesis. I am trying to write an llvm pass that just removes all "Add" commands and gives some statstics. Nevertheless, I get this segmentation fault: ................some rows about functions, that are not changed by my pass. The errors occurs after it

Hi, I have a question about ExtractLoop() in CodeExtractor.cpp. The sample code is a simple list traversal, as attached.

Dumb question: do you have a restrictive ulimit setting that might cause the tblgen program to run out of memory?

Tried a fresh checkout with the same issue.

John, Thanks for responding. No, I don't see a limit from ulimit. It's definitely with the tblgen though, I have the same errors trying to compile clang.

Usually it is the ones that end in ".inc".

Hi Ryan, Sometimes the configure machinery can get confused. I haven't seen this particular error, so I don't know for sure if that's happening here, though. Try running "./config.status" from the build directory. Perhaps unrelated, but it looks like you're building inside the source tree. I'd recommend not doing that, as it's not too uncommon for that to run

Here's another question. It's failing on a clean checkout, so what does llvm use from a previous install that I would need to clean when installing a new clean checkout?

Sorry, here's something a little more descript: core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 20 file size (blocks, -f) unlimited pending signals (-i) 16382 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024

Duncan, Yes, this is the problem. Running "opt -version" returns: me at here:~/llvm/llvm_core/llvm-2.9$ opt -version Low Level Virtual Machine (http://llvm.org/): llvm version 2.8 (Ubuntu 2.8-0ubuntu1) Optimized build.
