This script automatically instruments a program, runs it with the JIT, -then runs B<llvm-prof> to format a report. To get more information about -F<utils/profile.pl>, execute it with the B<-help> option. - -=head1 OPTIONS - -=over - -=item B<--annotated-llvm> or B<-A> - -In addition to the normal report printed, print out the code for the -program, annotated with execution frequency information. This can be -particularly useful when trying to visualize how frequently basic blocks -are executed. This is most useful with basic block profiling -information or better. - -=item B<--print-all-code> - -Using this option enables the B<--annotated-llvm> option, but it -prints the entire module, instead of just the most commonly executed -functions. - -=item B<--time-passes> - -Record the amount of time needed for each pass and print it to standard -error. - -=back - -=head1 EXIT STATUS - -B<llvm-prof> returns 1 if it cannot load the bitcode file or the profile -information. Otherwise, it exits with zero. - -=head1 AUTHOR - -B<llvm-prof> is maintained by the LLVM Team (L<http://llvm.org/>). - -=cut |
