similar to: [LLVMdev] Upgrading from llvm 2.8 to 3.0/3.1

I successfully ported our project from llvm-2.8 to llvm-3.0. The most important change is you need to change some argument type from Vector to llvm::ArrayRef, such as CallInst::Create, FunctionType::get etc. Until now , our project is running fine except some minor issue. I still need to look into if the current issues is related to llvm 3.0 Thanks all your help. Thanks MK On Wed, Jun 13, 2012

Hi, folks I am trying to build LLVM-GCC 4.2 on a Linux/PowerPC machine. Actually, the PowerPC is a PS3. The source was downloaded from http://llvm.org/releases/2.8/llvm-gcc-4.2-2.8.source.tgz Here is my system information and configuration options: ---------------------------------------------------------------------- $ uname -a Linux ps3 2.6.32-rc2-00995-g96ebbe6-dirty #2 SMP Fri Oct 2

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! Here is the pandaboard configuration,

But I already told Bill the platform I prepare to test and the testing day begins *tomorrow*, I prefer what it likes now. BTW, what if I use a cross compiler with hardfp enabled to compile LLVM first, then run it on Ubuntu/ARM? Does it achieve your goal, too?

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 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 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

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,

Now you can notice that the build proceed much further. Try to add --disable-libmudflap as well. -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

Hi, all I found the example code examples/HowToUseJIT.cpp also shows the same error. Attachment is the LLVM module created by HowToUseJIT. And here is the error, Running foo: %X4<def> = LDtoc <ga:@add1>, %X2 UNREACHABLE executed! Stack dump: 0. Running pass 'PowerPC Machine Code Emitter' on function '@foo' Aborted Currently, I use gdb try to track down

We are looking for ARMv7 cortex-a8 and cortex-a9 on Linux. We have two pandard board (ARMv7 cortex-a9) and perhaps one ARMv6 4-cores board. Do we do a native compile or cross compile for the ARM platform? Regards, chenwj --

Hello all, I caught a problem related to pthread library. I built llvm and llvm-gcc then compiling a multithreaded benchmark written in POSIX thread library. The command "llvm-gcc -o bench bench.c -lpthread" ran well while "llvm-gcc -c bench; llvm-ld -o bench bench.o -lpthread" crashed. It told that "llvm-ld: error: Cannot find library 'pthread'". I could

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

Hi, How can I dynamically change the code generation optimization level (e.g., None) of a JIT in other to recompile a function with a new optimization level (e.g., Default)? Thank you. Best regards, Nurudeen.

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
