| .IX Title "LLVM-UPGRADE 1" |
| .TH LLVM-UPGRADE 1 "2006-12-02" "CVS" "LLVM Command Guide" |
| .SH "NAME" |
| llvm\-upgrade \- LLVM assembly upgrader |
| .SH "SYNOPSIS" |
| .IX Header "SYNOPSIS" |
| \&\fBllvm-upgrade\fR [\fIoptions\fR] [\fIfilename\fR] |
| .SH "DESCRIPTION" |
| .IX Header "DESCRIPTION" |
| \&\fBllvm-upgrade\fR is the \s-1LLVM\s0 assembly upgrader. It reads a file containing |
| human-readable \s-1LLVM\s0 assembly language, and upgrades that assembly to the current |
| version of \s-1LLVM\s0. If the input is in the form currently accepted by \s-1LLVM\s0, then |
| no upgrades are performed. |
| .PP |
| The expected usage of this tool is as a filter, like this: |
| .Sp |
| .RS 4 |
| \&\fBllvm\-1.9/bin/llvm\-dis < 1.9.bc | llvm-upgrade | llvm\-2.0/bin/llvm\-as \-o 2.0.bc\fR |
| .RE |
| .PP |
| If \fIfilename\fR is omitted or is \f(CW\*(C`\-\*(C'\fR, then \fBllvm-upgrade\fR reads its input from |
| standard input. |
| .PP |
| If an output file is not specified with the \fB\-o\fR option, then |
| \&\fBllvm-upgrade\fR sends its output to standard output. |
| .SH "OPTIONS" |
| .IX Header "OPTIONS" |
| .IP "\fB\-f\fR" 4 |
| .IX Item "-f" |
| Force overwrite. Normally, \fBllvm-upgrade\fR will refuse to overwrite an |
| output file that already exists. With this option, \fBllvm-upgrade\fR |
| will overwrite the output file. |
| .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-upgrade\fR |
| sends its output to standard output. |
| .SH "EXIT STATUS" |
| .IX Header "EXIT STATUS" |
| If \fBllvm-upgrade\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" |
| llvm-as, llvm-dis |
| .SH "AUTHORS" |
| .IX Header "AUTHORS" |
| Maintained by the \s-1LLVM\s0 Team (<http://llvm.org>). |
