Hello There is not support for big endian ARM at all.

I guess he need to change the data layout string in ARMTargetMachine::ARMTargetMachine (ARMTargetMachine.cpp) from "e" to "E" to get big endian output?

That would be a start, but I'd expect a significant number of bugs where the backend writers have assumed ARM was little-endian (lib/Target/Mips, which *does* support both, has many more endian checks in the

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

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

You may need a ".nojekyll" file. uvbook has one < https://github.com/nikhilm/uvbook/blob/gh-pages/.nojekyll>.

Hi, I've been trying to set up clang/LLVM to compile for big endian ARM and I need a little help. The code generation works for the most part and most of my regression tests pass, but I noticed that code like this extern void g(void); int *p; int main() { if (*p & 0x01000000) g(); } generates ldr r0, [r0] ldrb r0, [r0, #3]

Hi, Currently, I can build lld/llvm on Fedora 17 but fail to build it on iMac. The commands I use as follows. Anyone can help me? Or is there the lld mail list I can post the question? Linux/Fedora can be built by the following command cmake -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_FLAGS=-std=c++11 -DCMAKE_BUILD_TYPE=Debug -G "Unix Makefiles" ../src/ make iMac

Ten days ago, I asked "Can I debug llvm source code by iMac Xcode?". I still cannot do it now, but I can debug llvm source code by iMac lldb. I write it down on section  "1.4  Create LLVM.xcodeproj of supporting cpu0 by terminal cmake command" of GammaLLVMBackendBook.pdf in https://www.dropbox.com/sh/2pkh1fewlq2zag9/r9n4gnqPm7  Best regards Jonathan

Hi, LLVM only support primitive type i32 and i64, no i48. The clang translate "C int type" to i32 too. My question is if a cpu is 48 bits register size, how to write the backend for 48 bits register architecture. Can someone help me with this problem?

Sean, It is not work even though I change the PDF link as you indicated. I think I can just use directory/link https://github.com/Jonathan2251/lbd/tree/gh-pages instead http://jonathan2251.github.com/lbd/WriteAnLLVMBackendTutorialForCpu0.pdf as a work around solution. User can click the link and click left top button "ZIP" and get the epub and pdf. Jonathan --- 12/12/4 (二)，Sean Silva

Sean, The `.. code-block:: bash` is work. Thank your information. Currently, I can put reStructuredText files on github. But, your example uvbook seems put the html and pdf on different github directory. Do you put html and pdf on github with version control?

Let me explain how uvbook does it. They use a feature of github called "github pages", which provides small static website hosting. The way that github pages works is that you make a git branch `gh-pages` which contains the generated HTML. They explain it better here <https://help.github.com/articles/creating-project-pages-manually>. You can see how uvbook does it by looking at
