.IX Title "LLVM-AS 1"
.TH LLVM-AS 1 "2006-03-13" "CVS" "LLVM Command Guide"
.SH "NAME"
llvm\-as \- LLVM assembler
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBllvm-as\fR [\fIoptions\fR] [\fIfilename\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBllvm-as\fR is the \s-1LLVM\s0 assembler.  It reads a file containing human-readable
\&\s-1LLVM\s0 assembly language, translates it to \s-1LLVM\s0 bytecode, and writes the result
into a file or to standard output.
.PP
If \fIfilename\fR is omitted or is \f(CW\*(C`\-\*(C'\fR, then \fBllvm-as\fR reads its input from
standard input.
.PP
If an output file is not specified with the \fB\-o\fR option, then
\&\fBllvm-as\fR sends its output to a file or standard output by following
these rules:
.IP "\(bu" 4
If the input is standard input, then the output is standard output.
.IP "\(bu" 4
If the input is a file that ends with \f(CW\*(C`.ll\*(C'\fR, then the output file is of
the same name, except that the suffix is changed to \f(CW\*(C`.bc\*(C'\fR.
.IP "\(bu" 4
If the input is a file that does not end with the \f(CW\*(C`.ll\*(C'\fR suffix, then the
output file has the same name as the input file, except that the \f(CW\*(C`.bc\*(C'\fR
suffix is appended.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-f\fR" 4
.IX Item "-f"
Force overwrite.  Normally, \fBllvm-as\fR will refuse to overwrite an
output file that already exists.  With this option, \fBllvm-as\fR
will overwrite the output file and replace it with new bytecode.
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
Print a summary of command line options.
.IP "\fB\-o\fR \fIfilename\fR" 4
.IX Item "-o filename"
Specify the output file name.  If \fIfilename\fR is \f(CW\*(C`\-\*(C'\fR, then \fBllvm-as\fR
sends its output to standard output.
.SH "EXIT STATUS"
.IX Header "EXIT STATUS"
If \fBllvm-as\fR succeeds, it will exit with 0.  Otherwise, if an error
occurs, it will exit with a non-zero value.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
