=head1 DESCRIPTION
The B<opt> command is the modular LLVM optimizer and analyzer. It takes LLVM
-bytecode as input, runs the specified optimizations or analyses on it, and then
-outputs the optimized LLVM bytecode or the analysis results. The function of
+bitcode as input, runs the specified optimizations or analyses on it, and then
+outputs the optimized LLVM bitcode or the analysis results. The function of
B<opt> depends on whether the B<-analyze> option is given.
When B<-analyze> is specified, B<opt> performs various analyses of LLVM
-bytecode. It will usually print the results on standard output, but in a few
+bitcode. It will usually print the results on standard output, but in a few
cases, it will print output to standard error or generate a file with the
analysis output, which is usually done when the output is meant for another
program.
While B<-analyze> is I<not> given, B<opt> attempts to produce an optimized
-bytecode file. The optimizations available via B<opt> depend upon what
+bitcode file. The optimizations available via B<opt> depend upon what
libraries were linked into it as well as any additional libraries that have
been loaded with the B<-load> option. Use the B<-help> option to determine
what optimizations you can use.
If I<filename> is omitted from the command line or is I<->, B<opt> reads its
-input from standard input. The input must be an LLVM bytecode file.
+input from standard input. The input must be an LLVM bitcode file.
If an output filename is not specified with the B<-o> option, B<opt>
writes its output to the standard output.
Force overwrite. Normally, B<opt> will refuse to overwrite an
output file that already exists. With this option, B<opt> will
-overwrite the output file and replace it with new bytecode.
+overwrite the output file and replace it with new bitcode.
