.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.
