Hi all, I'm one of the developers of the Jade project, a Jit decoder running with LLVM 2.9. We are currently testing our decoder on a pandaboard<http://pandaboard.org/> based on an OMAP 4430 and the Jit compilation seems to crash once there is a call to a function in the LLVM IR. We have already tested this issue with lli in its 2.9 version, and this bug still stays the same. LLVM 2.9, including lli, has been compiled on the board wit...

...ad it from their website. > > cheers, > --renato > Hi Renato, I'm not sure if this is not misunderstanding. As far as I know, CodeSourcery provides cross-compilers for ARM platforms and not native compilers. In my case I'm talking about native compiler running on Cortex-A9 (PandaBoard) and compiling LLVM directly on PandaBoard... The test cases I'm talking about are those which are directly packed in LLVM (test subdirectory) so you compile LLVM and then just invoke `make check' to test the build ... Thanks, Karel

I've used my i.MX53 board to get this, but I'm returning it today back to Freescale and my pandaboard is testing GHC performance so I'll not be able to get to this again earlier than next week. Anyway, JIT failures happens somewhere between 131458 (which is OK) and 131466 (where JIT tests fail). Let me know if this is enough or I shall continue to point to the culprit revision directly.

Hi all, Since the 3.1 testing day is coming and be a ARM tester, I would like to make sure everything is O.K. so that we don't waste the precious time. As discussed on the ML before, I plan to cross compile LLVM/Clang first, then run regression test and test suite on the pandaboards. Could someone help me check to see if I miss something? Thanks!

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...

Hello LLVM Devs, Thanks for helping me previously to cross-compile for ARM, I managed to get a working toolchain and am currently having fun compiling different toy problems and running them on a pandaboard. As part of my research I am trying to implement the ARM NEON Intrinsics in the PowerPC LLVM backend. I am still at the beginning of my efforts and am not yet familiar with either the ARM or the PowerPC backends. After I started investigating the code and found out that in total it is more than 10...

Obviously if they still break with MCJIT there |is something which definitely needs fixed. Yep, this is the issue. Running on an ARM pandaboard I can confirm that it's due to issues with the old JIT in general which are fixed in MCJIT, and nothing to do with the profiling code being tested, as discussed in this thread: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20120910/150406. html As you can see, I'm very inter...

Hi Renato, Thank you very much for the directions, I am going to recommit my fix. What are hardware used in buildbots? Are these common boards like PandaBoard or some thing special? What is RAM installed?

...Renato, It turned out I just didn't do the cross-compilation correctly, and Tim Northover already pointed me to a guide you have written on it ( http://clang.llvm.org/docs/CrossCompilation.html), so I will read that before continuing with my efforts. To answer your question I am testing on a pandaboard currently, which has an arm cortex-a9 processor, which I think is 64-bit. I am much happy to compile the latest code and am successfully doing so. I tried to compile release 2.9, as I (wrongly) believed that I need llvm-gcc in order to compile NEON code on LLVM. Tim's minimalist example worke...

Hello, A new clang builder added to osusl buildbot: http://google1.osuosl.org:8011/builders/clang-native-arm-cortex-a9 It's pandaboard with cortex-a9 runnibg Ubuntu 11.04. It builds Ok, but few test fail and need attention. Please take a look and let me know if someone will need more information or intermediate files to fix that. Thanks Galina

Hello, I'm trying to find myself, but anyway, I'm curious what's the recommended GNU C++ version for LLVM compilation on ARM/Linux platform? I'm using various version of Ubuntu and so far the best compiler I found was 4.4.1 (Ubuntu 4.4.1-4ubuntu9)[1]. With this and with just -O1 as optimize option I've been able to get to 1 failing testcase. Other tested were 4.4.3 and

Hi Karel, I'm not sure what test cases you're talking about, but we use CodeSourcery's GCC and binutils (latests, not stable, because of new core support) and it works a treat. You can

I tried to let it return "armv7l" or "cortex-a9" on pandaboard, but the bitcode output by clang still has target triple = "armv4t-unknown-linux-gnueabi" not what I expect target triple = "armv7l-unknown-linux-gnueabi" Do I miss something?
