=head1 DESCRIPTION
|
||||
|
||||
The B<opt> command is the modular LLVM optimizer and analyzer. It takes LLVM
|
||||
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
|
||||
source files as input, runs the specified optimizations or analyses on it, and then
|
||||
outputs the optimized file 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
|
||||
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.
