NAME¶llvm-extract - extract a function from an LLVM module
SYNOPSIS¶llvm-extract [options] –func function-name [filename]
DESCRIPTION¶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).
EXIT STATUS¶If llvm-extract succeeds, it will exit with 0. Otherwise, if an error occurs, it will exit with a non-zero value.
