.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
.B \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
.B \fB\-help\fP
Print a summary of command line options.
.TP
.B \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.
