This issue occurs by performing the following: Prerequisite: Have cmake 3.15.5 nstalled 1. Download LLVM-project 8.0.1 2. Open terminal, and create a build folder in the LLVM project source directory 3. Enter that build folder, and using cmake, create Unix Makefiles, via this command, "cmake -DLLVM_BUILD_INSTRUMENTED=IR -DLLVM_BUILD_RUNTIME=No -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ -DCMAKE_BUILD_TYPE=Release -G "Unix Makefiles" ../llvm" 4. Type "make -j8 all CFLAGS='-flto -O3 -fprofile-arcs -ftest-coverage -fbranch-probabilities -fprofile-abs-path' CXXFLAGS='-flto -O3 -fprofile-arcs -ftest-coverage -fbranch-probabilities -fprofile-abs-path" and press Enter When the build reaches 100%, notice how the machine freezes and forces the user to restart Expected Results: gcc compiles the tests and product files without issue. Actual Results: GCC freezes and causes the entire computer to freeze up.
