The RISC-V community makes extensive use of open source compiler technologies. The most widely used C/C++ compilers today are GCC by the GNU Project and Clang by the LLVM project. One of the stronger points of GCC is that its jump threading pass is more powerful than the same pass in LLVM, which also has difficulties in threading jumps used in CoreMark benchmarking. To mitigate it and improve our own LLVM solution, Codasip developed an innovative implementation of jump threading that helped us achieve significantly faster code and better CoreMark results.
