similar to: [LLVMdev] Obsolete PTX is NOT completely removed in 3.2 release

Removed from trunk. Pawel can decide if its necessary to update the tarballs. Thanks for the report! Apparently git-svn does not delete removed directories.

Hi Pawel, Sorry for the trouble. At first I think maybe we can upload a new release tarball not replacing it, sorry I didn't say it in the previous mail. IMHO, if you have to do something new after the post-release, make a "dot" release would be better. Perhaps you can write down this experience to benifit other LLVMRM in the future. :-) Regards, chenwj -- Wei-Ren Chen (陳韋任)

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 Justin, Is there any progress on new CUDA by llvm PTX?

Right, I forgot to update that originally. I also have a separate document in the works that goes into more detail for NVPTX.

I'm sorry if it is too funny, I just thought it could be a simple enough basic tutorial. If you are asking whether many people are interested particularly in Ada, then I don't think so. Ada here is just an illustration of "whatever unusual thing you need - you can do it with LLVM easily by pipelining different components". Anyway, if you think it could be useful for the website,

Hi Justin, I believe the PTX section in the link below need some love, updating "lib/Target/PTX" to "lib/Target/NVPTX" for example.

Please do not, under no circumstances, change the 3.2 release tarballs

Hi Justin, I download llvm-ptx-samples [1] and try to build them. I found it seems lack of a complete document on how to build them with LLVM/Clang/libclc. Do you think it's a good idea to put a complete document/tutorial in _one_ place? Currently, there are your website [2], LLVM [3], Clang and libclc websites [5] over there. I feel people might get lost among those websites. ;-) Here

Pawel, First, all your help with the 3.2 release is greatly appreciated. I do not think anyone is saying otherwise. I apologize for the lack of documentation regarding this issue. I do ask that you consult with previous release manager (myself or Bill) to determine what the best course of action is. There is a lot of room to improve our release process, but its a collaborative effort. You are
