This relands #86209 which was reverted because ./bin/llvm no longer accepted test paths in the source tree instead of the build tree. This was happening because `add_subdirectory(${LLVM_MAIN_SRC_DIR}/utils/llvm-lit` was called before all tsst suites were registered, and therefore it was missing the source->build dir mappings. Original commit message: I am currently trying to test the LLVM runtimes (including compiler-rt) against an installed LLVM tree rather than a build tree (since that is no longer available). Currently, the runtimes build of compiler-rt assumes that LLVM_BINARY_DIR is writable since it uses configure_file() to write there during the CMake configure stage. Instead, generate this file inside CMAKE_CURRENT_BINARY_DIR, which will match LLVM_BINARY_DIR when invoked from llvm/runtimes/CMakeLists.txt. I also needed to make a minor change to the hwasan tests: hwasan_symbolize was previously found in the LLVM_BINARY_DIR, but since it is generated as part of the compiler-rt build it is now inside the CMake build directory instead. I fixed this by passing the output directory to lit as config.compiler_rt_bindir and using llvm_config.add_tool_substitutions(). For testing that we no longer write to the LLVM install directory as part of testing or configuration, I created a read-only bind mount and configured the runtimes builds as follows: ``` $ sudo mount --bind --read-only ~/llvm-install /tmp/upstream-llvm-readonly $ cmake -DCMAKE_BUILD_TYPE=Debug \ -DCMAKE_C_COMPILER=/tmp/upstream-llvm-readonly/bin/clang \ -DCMAKE_CXX_COMPILER=/tmp/upstream-llvm-readonly/bin/clang++ \ -DLLVM_INCLUDE_TESTS=TRUE -DLLVM_ENABLE_ASSERTIONS=TRUE \ -DCOMPILER_RT_INCLUDE_TESTS=TRUE -DCOMPILER_RT_DEBUG=OFF \ -DLLVM_ENABLE_RUNTIMES=compiler-rt \ -DCMAKE_DISABLE_FIND_PACKAGE_LLVM=TRUE \ -DCMAKE_DISABLE_FIND_PACKAGE_Clang=TRUE \ -G Ninja -S ~/upstream-llvm-project/runtimes \ -B ~/upstream-llvm-project/runtimes/cmake-build-debug-llvm-git ``` Pull Request: https://github.com/llvm/llvm-project/pull/114307
