Sean, I can create html, pdf and epub, then put them on <https://github.com/Jonathan2251/lbd/tree/gh-pages>. The uvbook example as below can click the pdf link and pop up a download window while I cannot. The uvbook link is put on http://username.github.com/... while the "make gh-pages" put them on https://github.com/username/...  How can I have the download link like uvbook

Wei-Ren, Sorry, currently, I have an English helper in documentation. The cpu0 is my brother teaching material for college, and I did llvm backend compiler tutorial  for cpu0 since I didn't find a good tutorial in llvm backend design. As I know, there are many way to contribute back to open source or llvm. For example, write qemu for cpu0 is a extended work in cpu0 llvm backend design. Or

Hi Justin, I believe the PTX section in the link below need some love, updating "lib/Target/PTX" to "lib/Target/NVPTX" for example. Would you like to take a look? http://llvm.org/docs/CodeGenerator.html#the-ptx-backend Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia Sinica, Taiwan (R.O.C.)

How about sending a patch which remove those obsolete code, and let others give comment? Cheers, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab,

Hi all, I think it's Gentoo's bug, but I want to know if anyone has the same issue here.

Hi all, While building/testing LLVM/Clang on ARM, I often have problems that are undocumented on the website. I would like to contribute my experience if possible so that others can benefit from it.

Hi Pawel, PTX already be replaced with NVPTX. However, PTX subdirectory still sit in lib/Target in 3.2 release. Do you think update the release tarball is a good idea? Also could you remove it from the trunk? Thanks. Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia Sinica, Taiwan (R.O.C.)
