For example, if a pass has a hidden option that controls some knob, you should only find out about it by reading the code. We don't want people surfing through all the hidden options to "see what is available". I see. Maybe we can tell people the existence of "-help-hidden" and also

You can download LLVM x86 binary from the website, which makes the testing easier.

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 have a trouble with calling external functions on PowerPC. What I am doing is generating a LLVM IR first like this, - x86 call void @helper_shack_flush(%struct.CPUX86State* %62) noinline, !flags !12 - ppc call void @helper_shack_flush(%struct.CPUX86State* %62) noinline, !flags !10 After lowering above LLVM IR for x86 and ppc, it becomes: - x86 %RAX<def> = MOV64ri

Hi all, I think it's Gentoo's bug, but I want to know if anyone has the same issue here. I am compiling LLVM trunk on Gentoo (gcc 4.5.2), and I get error message below, --- make[4]: Entering directory `/nfs_home/chenwj/llvm-3.1/svn/build/tools/clang/lib/Frontend' llvm[4]: Compiling InitHeaderSearch.cpp for Release+Asserts build

Turns out I was using `opt -profile-loader` instead of `opt -path-profile-loader`. Switching to the path profile loader fixed the problem.

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. If this is a good idea, I am wondering on what page I should write it down, [1] or [2]? Regards, chenwj [1] http://llvm.org/docs/GettingStarted.html [2] http://llvm.org/docs/FAQ.html -- Wei-Ren

Hi, all I found the example code examples/HowToUseJIT.cpp also shows the same error. Attachment is the LLVM module created by HowToUseJIT.

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.)

Hi, Sorry I did not precise that, but I'm already doing that... I have, as you say, two different director, one for source and one for build (where I run my configure)...

Hi! I was trying to run an already build LLVM-pass ( the Hello world ) on Visual Studio. I could locate the The Hello world pass sources in llvm/lib/Transform/Hello/*.But when I compiled llvm using the command "cmake -G "Visual Studio 10" ..\llvm" , I couldn't find the LLVMHello.so file in "build_directory/Debug/lib/LLVMHello.so" neither in
