.SH SYNOPSIS
|
|
.sp
|
|
\fBllvm\-extract\fP [\fIoptions\fP] \fB\-\-func\fP \fIfunction\-name\fP [\fIfilename\fP]
|
|
.SH DESCRIPTION
|
|
.sp
|
|
The \fBllvm\-extract\fP 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.
|
|
.sp
|
|
In addition to extracting the bitcode of the specified function,
|
|
\fBllvm\-extract\fP will also remove unreachable global variables, prototypes, and
|
|
unused types.
|
|
.sp
|
|
The \fBllvm\-extract\fP 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 \fB\-o\fP option is specified (see below).
|
|
.SH OPTIONS
|
|
.sp
|
|
\fB\-f\fP
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
Enable binary output on terminals. Normally, \fBllvm\-extract\fP will refuse to
|
|
write raw bitcode output if the output stream is a terminal. With this option,
|
|
\fBllvm\-extract\fP will write raw bitcode regardless of the output device.

|
|
.INDENT 3.5
|
|
Extract the function named \fIfunction\-name\fP from the LLVM bitcode. May be
|
|
specified multiple times to extract multiple functions at once.

.INDENT 3.5
|
|
Extract the function(s) matching \fIfunction\-regular\-expr\fP from the LLVM bitcode.
|
|
All functions matching the regular expression will be extracted. May be
|
|
specified multiple times.

.INDENT 0.0
|
|
.INDENT 3.5
|
|
Extract the global variable named \fIglobal\-name\fP from the LLVM bitcode. May be
|
|
specified multiple times to extract multiple global variables at once.

.INDENT 0.0
|
|
.INDENT 3.5
|
|
Extract the global variable(s) matching \fIglobal\-regular\-expr\fP from the LLVM
|
|
bitcode. All global variables matching the regular expression will be extracted.
|

May be specified multiple times.

|
\fBllvm\-extract\fP sends its output to standard output.

.SH EXIT STATUS
|
|
.sp
|
|
If \fBllvm\-extract\fP succeeds, it will exit with 0. Otherwise, if an error
|
|
occurs, it will exit with a non\-zero value.
