Hi David Blaikie and others who might be interested on this Thank you very much! #1. Then I'd like to know, to make Clang/LLVM optimize a recursion into an iteration, how a recursion has to be implemented with any compiler option? (if the language is C/C++) Clang uses recursions, especially it uses recursive decent and operator-precedence parser. #2. I wonder if this kind of recursion is

Hello David Chisnall, John McCall, David Blaikie and other people who may concern > If your teachers are really making this sort of superficial generalization, > they're doing you a disservice. This hit my head. Actually I didn't test the performance of those two, the iteration and the recursion, at all. And in this field of study, testing is very much important, I believe. And

I completely agree with John here - we had a case a few years ago where someone spent ages refactoring their algorithm to be iterative and was surprised that it became slower (with the MS compiler). Looking at the assembly, it was

And for this kind of question I think I would better hold in. There would be more important issue worth on this list. For this reason I am sorry. Sincerely Journeyer 2013/1/15 Journeyer J.

Hello, I just applied changes of LLVM 3.2 and it is tested with LLVM 3.2 downloaded from the LLVM Download Page. I just worked for master branch only. The rest of the other branches need to be changed about this also. This will be done as soon as possible. (Before I fix this, If you look at the commits for this issue for master branch, you can easily fix it and test for others also.) Sorry for

I am testing it with LLVM 3.2 wait a minute. -- Journeyer 2012/12/30 Sean Silva <silvas at purdue.edu>: > On Sat, Dec 29, 2012 at 9:45 PM, Journeyer J.

Hi Sean Silva, Maybe I am the only one who is trying to use UML. In my team, I am also the only one who draws UML diagrams. I expected there be someone who use UML like me. But it's maybe not as your opinion. Maybe doxygen is enough for majority of people. Thanks for your reply. Sincerely Journeyer J.

Klang is tested with LLVM 3.1 Header file location is often changed. I guess that's why..

Thanks, Journeyer. I applied the patch with r176235. In future, you can submit patches to the llvm-commits mailing list. :) -bw On Feb 27, 2013, at 9:03 PM, Journeyer J.

Hello list, I use LLVM's vimrc and found that this setting below is useful when editing of reStructuredText file. llvm/utils/vim/vimrc " Enable syntax highlighting for reStructuredText files. To use, copy " rest.vim (http://www.vim.org/scripts/script.php?script_id=973) " to ~/.vim/syntax . augroup filetype au! BufRead,BufNewFile *.rst set filetype=rest augroup END

Oh I see. Thank you. I will study that.

Hello Peng Yu and List, I have put toy.cpp into github but it has a form of LLVM project makefile infrastructure. So you can build it together with LLVM Project source tree. git://github.com/Journeyer/klang.git There exist many branches and each branch is for each chapter of Kaleidoscope.

Hello list, I'd like to know if people use UML tool to analyze and/or document LLVM/Clang. I use StarUML. It's free and very good though it's free. But I consider using a commercial program. Because the organization I belong is willing to support for this. I don't think I will use these tools to write code. I think I will use these to do a documentation and analyze code. So the

Hi Joerg, Thank you very much! I finally found a working command string to cross-compile for ARM on x86. ./clang -v --save-temps -ccc-host-triple arm-none-linux-gnueabi --sysroot=/home/hum/Documents/Projects/arm_toolchain/arm-2010.09/arm-none-linux-gnueabi/libc -gcc-toolchain /home/hum/Documents/Projects/arm_toolchain/arm-2010.09 hello.c -o hello Above works fine!

Hello Peng Yu, I found the same error on my Macbook Air. This was my first trying on MacOS X. Troubleshooting this might take sometime. Only thing I can say now that klang is tested successfully on Ubuntu with - LLVM 3.2 official release on LLVM download page - LLVM svn latest update Clang compile produces an error message on MacOS X with the LLVM svn latest update I am trying to find the
