Hi, I am trying to build my own llvmc plugin, but somehow, the llvm makefiles do not pick up the plugin in the llvmc/plugins directory anymore in a recent (r129445) svn checkout. According to the tutorial (http://llvm.org/docs/CompilerDriverTutorial.html): $ cd tools/llvmc $ cp -r example/Simple plugins/Simple $ make LLVMC_BASED_DRIVER_NAME=mygcc LLVMC_BUILTIN_PLUGINS=Simple does not build

The problem I'm experiencing with Stacker has to do with linkage types (again!). What I'm trying to do is create a "global appending" array. In compilation units that don't include "main", I generate it with: TheStack = new GlobalVariable( /*type=*/ stack_type, /*isConstant=*/ false, /*Linkage=*/

Either always run the driver via an alias, or edit lib/CompilerDriver/BuiltinOptions.cpp: cl::opt<SaveTempsEnum::Values> SaveTemps ("save-temps",

I found out the problem. Looks like I can not rely on argv[0] to contain the full path of the executable always. Can I rely on: static Path GetMainExecutable(const char *argv0, void *MainAddr); is it Cross-platform? What to pass for second parameter here. C++ forbids taking address of "main", and the "Main" of CompilerDriver is in a shared object here. - Sanjiv Sanjiv

If you would like to work on it, patches are welcomed! Thanks, Tanya > $ llvmc -c a.c -o a.o > /usr/src/llvm/dist/etc/llvm/c:55: Error: Expecting output

Is llvmc meant for compilation? $ llvmc -c a.c -o a.o /usr/src/llvm/dist/etc/llvm/c:55: Error: Expecting output type value /usr/src/llvm/dist/etc/llvm/c had 1 errors. Terminating. The offending line contains: optimizer.output = bytecode which doesn't seem to be understood by llvmc. If I uncomment this line, I get another error message: $ llvmc -c a.c -o a.o llvmc: Can't find program

I'm building a static analysis tool on top of LLVM. It needs to take in a C++ source file and have LLVM translate it into bitcode. In other words, it basically needs to do this: llvmc hello.cpp -emit-llvm -O0 -S -g Except that instead of writing the bitcode to a file, it needs to load it into memory (presumably as an instance of Module) for further processing and analysis. So my

I am getting this error while using the command "llvmc -O3 -Wall hello.cpp" where hello.cpp is some cpp file on my machine. llvmc is the driver calling a bunch of tools like llvm-g++, opt, llc etc. I think the llvmc tool could not probably locate the llvm-g++ tool. I would like to know where should I specify the path to llvm-g++ for llvmc to find them. Also can someone give me the link

Hi, Is it intended that llvmc should search PATH for llc? For example, this means that llvmc 2.7 can invoke llc 2.8: % echo $PATH /home/jdenny/installs/llvm/2.8/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games % /home/jdenny/installs/llvm/2.7/bin/llvmc test.ll llc: Unknown command line argument '-f'. Try: 'llc -help' % strace -f

I still get errors while building examples. i00202 at ubuntu:~/projects/llvm/tools/llvmc/example/mcc16$ make make[1]: Entering directory `/home/i00202/projects/llvm/tools/llvmc/example/mcc16/plugins' make[2]: Entering directory

Without this patch, opt is never called for llvm-assembly (.ll) files when "-opt" is passed to llvmc: $ llvmc -clang -v test.ll llc -f -O2 test.ll -o /tmp/llvm_gvO2nK/test.s as /tmp/llvm_gvO2nK/test.s -o /tmp/llvm_gvO2nK/test.o llvm-ld -native -disable-internalize /tmp/llvm_gvO2nK/test.o -o a.out $ llvmc -clang -opt -v test.ll llc -f -O2 test.ll -o /tmp/llvm_2xiL86/test.s as

Thank you so much for your reply, Chris. If so, can I ask you two things more? First, is there any way to have various optimizations on LLVM assembly such as -O options in llvmc? llvm-gcc doesn't seem to be working for these -O options... Second, I'm still not sure about difference between *.s and *.ll. LLVM assembly *.s file can be made from llvm-gcc with -S option. Another

Greetings everybody! In my quest to attract more users to llvmc, I've added support for compilation via the Clang front-end (previously, only llvm-gcc was supported). This is enabled with the '-clang' switch; basically, you can now just alias 'ccc' to 'llvmc -clang' and get the same functionality. Examples: Compile via Clang: $ llvmc -clang test.c

I was using llvmc along with the -opt option to perform static analyzes in some of the commonly used programs like bzip2, gzip, grep etc. I found that when llvmc is used to link libraries (.a or .so files) using the -l option it passes the library files to the linker ( for me it was llvm-gcc itself) but changes the order in which it was given to llvmc. Eg: the command: " llvmc -o grep.o -v
