llvm-extract - extract a function from an LLVM module


llvm-extract [options] --func function-name [filename]


The llvm-extract command takes the name of a function and extracts it from the specified LLVM bitcode file. It is primarily used as a debugging tool to reduce test cases from larger programs that are triggering a bug.

In addition to extracting the bitcode of the specified function, llvm-extract will also remove unreachable global variables, prototypes, and unused types.

The llvm-extract command reads its input from standard input if filename is omitted or if filename is -. The output is always written to standard output, unless the -o option is specified (see below).


Enable binary output on terminals. Normally, llvm-extract will refuse to write raw bitcode output if the output stream is a terminal. With this option, llvm-extract will write raw bitcode regardless of the output device.
--func function-name
Extract the function named function-name from the LLVM bitcode. May be specified multiple times to extract multiple functions at once.
--glob global-name
Extract the global variable named global-name from the LLVM bitcode. May be specified multiple times to extract multiple global variables at once.
Print a summary of command line options.
-o filename
Specify the output filename. If filename is ``-'' (the default), then llvm-extract sends its output to standard output.
Write output in LLVM intermediate language (instead of bitcode).


If llvm-extract succeeds, it will exit with 0. Otherwise, if an error occurs, it will exit with a non-zero value.
