I'm having the same problem. Does anyone know what's causing this?

I can only guess llvm-prof does not recognize the profiling data. Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia

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

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.)

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 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

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

In other words, this test case guarantee that pr1028 will not back again. If so, it will fail.

Hi all, I have been stuck on compiling LLVM/Clang (r163485) on pandaboard which has following configuration, - Ubuntu 11.04 + 1G Mem + 1G Swap + 32G SD card - GCC 4.5.2 - GNU gold (GNU Binutils for Ubuntu 2.21.0.20110327) 1.11 The compiling process stucks on linking llc, I am pretty surprised on this. Anyone has similar issue or any idea? Thanks! Regards, chenwj -- Wei-Ren Chen (陳韋任)
