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! 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

Hi all, I think it's Gentoo's bug, but I want to know if anyone has the same issue here.

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

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

I want to connect each llvm ir for example: 1. Turn C/C++ language into C_llvmIR assembly language using Clang 2. Turn Fortran language into Fortran_llvmIR assembly language using Dragonegg 3. Turn Python language into Python_llvmIR assembly language using Unladen-Swallow 4. Connect each llvm IR Is this possible? Wonjun, Choi -------------- next part -------------- An HTML attachment was

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 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
