LLI Command Options
The syntax to execute programs in LLVM bitcode format with GraalVM is:
lli [LLI options] [GraalVM options] [polyglot options] <bitcode file> [program args]
<bitcode file> is a compiled program with embedded LLVM bitcode.
The following options to
lli are available:
--llvm.managed: enable a managed execution mode for LLVM IR code, which means memory allocations from LLVM bitcode are done on the managed heap. Learn more from Limitations and Differences to Native Execution. Note: Managed execution mode for LLVM bitcode is possible with GraalVM Enterprise only.
--print-toolchain-path: print the path of the LLVM toolchain bundled with GraalVM. This directory contains compilers and tools that can be used to compile C/C++ programs to LLVM bitcode for execution on GraalVM.
--print-toolchain-api-tool <tool>: print the path of a tool from the LLVM toolchain. Valid values for
--print-toolchain-api-paths <path>: print a search path for the LLVM toolchain. Valid values for
--print-toolchain-api-identifier: print a unique identifier of the LLVM toolchain. Different modes of the LLVM runtime (e.g.,
--llvm.managed) might require compilation of bitcode with a different LLVM toolchain. This identifier can be used as a stable directory name to store build outputs for different modes.
--llvm.libraryPath=<path>: a list of paths where GraalVM will search for library dependencies. Paths are delimited by
--llvm.libraries=<libs>: a list of libraries to load in addition to the dependencies of the main binary. Files with a relative path are looked up relative to
llvm.libraryPath. Entries are delimited by
--version: print the version and exit.
--version:graalvm: print the GraalVM version information and exit.
