What version of LLVM and Clang you are using? I have no such problem on my machine. Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab,

Hello all, I'm brand new to using LLVM and am having trouble using lli with a C++ program. I tried to compile the following: #include<iostream> using namespace std; int main() { cout << "Hello, world!" << endl; return 0; } When I compile directly to an executable with the following command, all is well: $ clang++ -O3 hello.cpp -o hello But when I try to produce

Could you tell me the current status of MIPS JIT?

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 James, Thanks for your information. Could you suggest any other framework that I could use for making a custom JIT for ARM? I am doing research on JIT compilation for a heterogeneous processor system.

Hello, I'm not very familiar with the autotools, so please bear with this message if the solution is too obvious. I am using 64 bit Linux and gcc 4.7.1. I just built llvm and clang from the trunk and as the binaries installed in /usr/local/bin seem to be working correctly, I guess the compilation has gone okay. Note that, at this point, I'm not trying to make a separate project, which is

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, Does anyone know which version of LLVM support "opt --insert-block-profiling command"? Thanks!

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, 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.

Sorry that I have implemented nothing for it. aget is not my own project which is a public project of paralell "wget". I only want to use it as a common benchmark.  Do I need to implement anything for it?

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