() () NAME LFortran - modern interactive LLVM-based Fortran compiler SYNOPSIS lfortran OPTIONS [files...] [SUBCOMMAND] DESCRIPTION LFortran is a modern interactive Fortran compiler based on LLVM. OPTIONS • -h, --help: Print this help message and exit • -S: Emit assembly, do not assemble or link • -c: Compile and assemble, do not link • -o TEXT: Specify the file to place the compiler's output into • -v: Be more verbose • -E: Preprocess only; do not compile, assemble, or link • -l TEXT ...: Link library option • -L TEXT ...: Library path option • -I TEXT ...: Include path • -J TEXT: Where to save mod files • -g: Compile with debugging information • -D TEXT ...: Define <macro>=<value> (or 1 if <value> omitted) • --version: Display compiler version information • -W TEXT ...: Linker flags • -f TEXT ...: All -f* flags (only -fPIC supported for now) • --cpp: Enable C preprocessing • --fixed-form: Use fixed form Fortran source parsing • --fixed-form-infer: Use heuristics to infer if a file is in fixed form • --no-prescan: Turn off prescan • --show-prescan: Show tokens for the given file and exit • --show-tokens: Show tokens for the given file and exit • --show-ast: Show AST for the given file and exit • --show-asr: Show ASR for the given file and exit • --with-intrinsic-mods: Show intrinsic modules in ASR • --show-ast-f90: Show Fortran from AST for the given file and exit • --no-color: Turn off colored AST/ASR • --no-indent: Turn off Indented print ASR/AST • --tree: Tree structure print ASR/AST • --json: Print ASR/AST Json format • --clojure: Print ASR in clojure format • --no-loc: Skip location information in ASR/AST Json format • --visualize: Print ASR/AST Visualization • --pass TEXT: Apply the ASR pass and show ASR (implies -show-asr) • --skip-pass TEXT: Skip an ASR pass in the default pipeline • --show-llvm: Show LLVM IR for the given file and exit • --show-cpp: Show C++ translation source for the given file and exit • --show-c: Show C translation source for the given file and exit • --show-asm: Show assembly for the given file and exit • --show-wat: Show WAT (WebAssembly Text Format) and exit • --show-julia: Show Julia translation source for the given file and exit • --show-fortran: Show Fortran translation source for the given file and exit • --show-stacktrace: Show internal stacktrace on compiler errors • --symtab-only: Only create symbol tables in ASR (skip executable stmt) • --time-report: Show compilation time report • --static: Create a static executable • --no-warnings: Turn off all warnings • --no-error-banner: Turn off error banner • --continue-compilation: Collect error messages and continue compila- tion after encountering semantic errors • --error-format TEXT=human: Control how errors are produced (human, short) • --backend TEXT=llvm: Select a backend (llvm, cpp, x86, wasm, fortran) • --openmp: Enable OpenMP • --separate-compilation: Generate object code into .o files • --rtlib: Include the full runtime library in the LLVM output • --use-loop-variable-after-loop: Allow using loop variable after the loop • --fast: Best performance (disable strict standard compliance) • --link-with-gcc: Calls GCC for linking instead of clang • --target TEXT: Generate code for the given target • --print-targets: Print the registered targets • --implicit-typing: Allow implicit typing • --implicit-interface: Allow implicit interface • --implicit-argument-casting: Allow implicit argument casting • --print-leading-space: Print leading white space if format is unspec- ified • --interactive-parse: Use interactive parse • --verbose: Print debugging statements • --dump-all-passes: Apply all the passes and dump the ASR into a file • --dump-all-passes-fortran: Apply all passes and dump the ASR after each pass into a Fortran file • --cumulative: Apply all the passes cumulatively till the given pass • --realloc-lhs-arrays: Reallocate left hand side automatically for ar- rays • --disable-realloc-lhs-arrays: Disables reallocating left hand side automatically for arrays • --module-mangling: Mangles the module name • --global-mangling: Mangles all the global symbols • --intrinsic-mangling: Mangles all the intrinsic symbols • --all-mangling: Mangles all possible symbols • --bindc-mangling: Mangles functions with ABI bind(c) • --apply-fortran-mangling: Mangle symbols with Fortran supported syn- tax • --mangle-underscore: Mangles with underscore • --legacy-array-sections: Enables passing array items as sections if required • --ignore-pragma: Ignores all the pragmas • --stack-arrays: Allocate memory for arrays on stack SUBCOMMANDS • fmt: Format Fortran source files. • kernel: Run in Jupyter kernel mode. • mod: Fortran mod file utilities. • pywrap: Python wrapper generator SEE ALSO For more information, visit the official LFortran documentation at https://docs.lfortran.org/.
