...from binutils 2.22, and placed LLVMgold.so in /usr/bin/bfd-plugins. The host system is Ubuntu 11.10. CFLAGS and CXXflags are all set to include "-emit-llvm". First, I create libjscore.a with ar, where I've changed the command line to load the plugin: ar cqs --plugin /home/tmjackso/multicompiler/llvm-3.0/release/lib/LLVMgold.so libjscore.a <list of object files> Then I link jsc against libjscore.a: /home/tmjackso/multicompiler/llvm-3.0/release/bin/clang++ -Wl,-plugin,/home/tmjackso/multicompiler/llvm-3.0/release/lib/LLVMgold.so -Wl,-rpath,/home/tmjackso/builds/qt/qt-4.8.1/lib -Wl,-r...

I read a lot of white papers, but is there not any open source implementation of SFI or artificial diversity? I google around, but I can't find anywhere anything regarding what I could openly download. In the same respect, I would also like to make an innovation proposal to create such an endeavor if there is not one already. -------------- next part -------------- An HTML attachment was

...LLVM build took me about 15 minutes. The only change to the pre-existing LLVM CMake specification was if( EXISTS ${CMAKE_CURRENT_SOURCE_DIR}/clang/CMakeLists.txt ) add_subdirectory( ${CMAKE_CURRENT_SOURCE_DIR}/clang ) endif() and just this gives a lot of benefit: parallel builds, multiplatform, multicompiler, robustness, etc. With some work it is possible to support building clang on an arbitrary directory, even putting LLVM as a subdirectory of clang, which is more natural than the current arrangement. This feature could be of benefit to those working on their own compiler too: integrating LLVM on a e...

Hi! I have written a ModulePass that calculates various things and adds custom metadata attributes to certain instructions. Depending on the attributes, I would like to change the machine code of these instructions. For example, I would like to replace certain calls with jumps, but as far as I can tell the IR metadata is not accessible anymore on the level of machine instructions (e.g. in the
