.SH SYNOPSIS
.sp
\fBllvm\-as\fP [\fIoptions\fP] [\fIfilename\fP]
.SH DESCRIPTION
.sp
\fBllvm\-as\fP is the LLVM assembler.  It reads a file containing human\-readable
LLVM assembly language, translates it to LLVM bitcode, and writes the result
into a file or to standard output.
.sp
If \fIfilename\fP is omitted or is \fB\-\fP, then \fBllvm\-as\fP reads its input from
standard input.
.sp
If an output file is not specified with the \fB\-o\fP option, then
\fBllvm\-as\fP sends its output to a file or standard output by following
these rules:
.INDENT 0.0
.IP \(bu 2
If the input is standard input, then the output is standard output.
.IP \(bu 2
If the input is a file that ends with \fB\&.ll\fP, then the output file is of the
same name, except that the suffix is changed to \fB\&.bc\fP\&.
.IP \(bu 2
If the input is a file that does not end with the \fB\&.ll\fP suffix, then the
output file has the same name as the input file, except that the \fB\&.bc\fP
suffix is appended.
.UNINDENT
.SH OPTIONS
.INDENT 0.0
.TP
\fB\-f\fP
Enable binary output on terminals.  Normally, \fBllvm\-as\fP will refuse to
write raw bitcode output if the output stream is a terminal. With this option,
\fBllvm\-as\fP will write raw bitcode regardless of the output device.
.TP
\fB\-help\fP
Print a summary of command line options.
.TP
\fB\-o\fP \fIfilename\fP
Specify the output file name.  If \fIfilename\fP is \fB\-\fP, then \fBllvm\-as\fP
sends its output to standard output.
.UNINDENT
.SH EXIT STATUS
.sp
If \fBllvm\-as\fP succeeds, it will exit with 0.  Otherwise, if an error occurs, it
will exit with a non\-zero value.
