Only "host tools" platforms have a pre-compiled snapshot binary available; to compile for a platform without host tools you must cross-compile. WebSep 19, 2024 · The most impactful way to reduce binary size is to dynamically link LLVM into all the tools. This reduces code size by decreasing duplication of common code between the LLVM-based tools. This can be done by setting the following two CMake options to On: LLVM_BUILD_LLVM_DYLIB and LLVM_LINK_LLVM_DYLIB.

WebThe llvm-link works using the basic functionality of a linker—that is, if a function or variable referenced in one file is defined in the other file, it is the job of linker to resolve all the references made in a file and defined in the other file. But note that this is not the traditional linker that links various object files to generate a binary. http://s2e.systems/docs/Tutorials/Revgen/Revgen.html#:~:text=Translating%20binaries%20to%20LLVM%20with%20Revgen%20Revgen%20is,chunk%20of%20LLVM%20bitcode%20by%20using%20QEMU%E2%80%99s%20translator
