Make it convenient to learn llvm and mlir.

Build llvm & mlir

This is an example work-flow and configuration to get and build the LLVM source:

  • cmake -S llvm -B build -G <generator> -DLLVM_ENABLE_PROJECTS='llvm;mlir' [options]

    Some common build system generators are:

    • Ninja --- for generating Ninja build files. Most llvm developers use Ninja.
    • Unix Makefiles --- for generating make-compatible parallel makefiles.
    • Visual Studio --- for generating Visual Studio projects and solutions.
    • Xcode --- for generating Xcode projects.

    Some Common options:

    • -DCMAKE_INSTALL_PREFIX=directory --- Specify for directory the full path name of where you want the LLVM tools and libraries to be installed (default /usr/local).

    • -DCMAKE_BUILD_TYPE=type --- Valid options for type are Debug, Release, RelWithDebInfo, and MinSizeRel. Default is Debug.

    • -DLLVM_ENABLE_ASSERTIONS=On --- Compile with assertion checks enabled (default is Yes for Debug builds, No for all other build types).

  • cmake --build build [-- [options] <target>] or your build system specified above directly.

    • The default target (i.e. ninja or make) will build all of LLVM.

    • The check-all target (i.e. ninja check-all) will run the regression tests to ensure everything is in working order.

    • CMake will generate targets for each tool and library, and most LLVM sub-projects generate their own check-<project> target.

    • Running a serial build will be slow. To improve speed, try running a parallel build. That's done by default in Ninja; for make, use the option -j NNN, where NNN is the number of parallel jobs, e.g. the number of CPUs you have.
