See "macOS with Homebrew LLVM" section above. + +2. **Build LLVM from source** with static libraries (the default for our + superbuild). See "Full Superbuild" above. + +**Technical details:** Homebrew builds LLVM with `LLVM_BUILD_LLVM_DYLIB=ON` and +`LLVM_LINK_LLVM_DYLIB=ON`. This causes `AnalysisManager::getResultImpl` to be +instantiated in libLLVM.dylib, but the `AnalysisKey` for rellic's `GenerateAST` +pass is in the rellic binary. When the manager searches for the key, it doesn't +find it because the key addresses differ between the dylib and the application. + +The `RELLIC_FORCE_STATIC_LLVM` option works by modifying the +`INTERFACE_LINK_LIBRARIES` property of Clang targets to replace `LLVM` (the +shared library target) with all static LLVM component libraries. + +### Z3 build fails + +Use an external Z3 installation: + +```sh +cmake -G Ninja -S dependencies -B dependencies/build \ + -DUSE_EXTERNAL_LLVM=ON \ + -DUSE_EXTERNAL_Z3=ON +``` diff --git a/dependencies/llvm.cmake b/dependencies/llvm.cmake new file mode 100644 index 00000000..05c38214 --- /dev/null +++ b/dependencies/llvm.cmake @@ -0,0 +1,41 @@ +option(LLVM_ENABLE_ASSERTIONS "Enable assertions in LLVM" ON) + +# Default values for LLVM_URL and LLVM_SHA256.
