NAME¶
llvm-extract - extract a function from an LLVM moduleSYNOPSIS¶
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.OPTIONS¶
-fEnable 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.
Extract the function named
function-name from the LLVM bitcode. May be specified multiple times to
extract multiple functions at once.
Extract the function(s) matching
function-regular-expr from the LLVM bitcode. All functions matching the
regular expression will be extracted. May be specified multiple times.
Extract the global variable named
global-name from the LLVM bitcode. May be specified multiple times to
extract multiple global variables at once.
Extract the global variable(s) matching
global-regular-expr from the LLVM bitcode. All global variables
matching the regular expression will be extracted. May be specified multiple
times.
Print a summary of command line options.
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).
EXIT STATUS¶
If llvm-extract succeeds, it will exit with 0. Otherwise, if an error occurs, it will exit with a non-zero value.SEE ALSO¶
