LLVM: extract tool
NAME
extract
SYNOPSIS
extract [options] [filename]
DESCRIPTION
The extract command takes the name of a function and extracts it from
the specified LLVM bytecode 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 bytecode of the specified function,
extract will also remove unreachable global variables, prototypes, and
unused types.
The extract command reads its input from standard input if filename is
omitted or if filename is -. The output is always written to standard output.
OPTIONS
- -f
Force overwrite. Normally, extract will refuse to overwrite an
output file that already exists. With this option, extract
will overwrite the output file and replace it with new bytecode.
- -func <function>
Extract the specified function from the LLVM bytecode.
- -help
Print a summary of command line options.
- -o <filename>
Specify the output filename. If filename is "-" (the default), then
extract sends its output to standard output.
- -stats
Print statistics.
- -time-passes
Record the amount of time needed for each pass and print it to standard
error.
EXIT STATUS
If extract succeeds, it will exit with 0. Otherwise, if an error
occurs, it will exit with a non-zero value.
