It takes a program in +LLVM bytecode format and executes it using a just-in-time compiler, if one is +available for the current architecture, or an interpreter. B<lli> takes +all of the same code generator options as L<llc|llc>, but they are only effective +when B<lli> is using the just-in-time compiler. + +If I<filename> is not specified, then B<lli> reads the LLVM bytecode for the +program from standard input. + +The optional I<args> specified on the command line are passed to the program as +arguments. + +=head1 OPTIONS + +=over + +=item B<-help> + +Print a summary of command line options. + +=item B<-stats> + +Print statistics from the code-generation passes. This is only meaningful for +the just-in-time compiler, at present. + +=item B<-time-passes> + +Record the amount of time needed for each code-generation pass and print it to +standard error. + +=item B<-march>=I<arch> + +Use the specified non-default architecture arch when selecting a code generator +for the just-in-time compiler. This may result in a crash if you pick an +architecture which is not compatible with the hardware you are running B<lli> on. + +=item B<-force-interpreter>=I<{false,true}> + +If set to true, use the interpreter even if a just-in-time compiler is available +for this architecture. Defaults to false. + +=item B<-f>=I<name> + +Call the function named I<name> to start the program. Note: The +function is assumed to have the C signature C<int> I<name> C<(int, +char **, char **)>. If you try to use this option to call a function of +incompatible type, undefined behavior may result. Defaults to C<main>. + +=back + +=head1 EXIT STATUS + +If B<lli> fails to load the program, it will exit with an exit code of 1. +Otherwise, it will return the exit code of the program it executes. + +=head1 SEE ALSO + +L<llc> + +=head1 AUTHOR + +Maintained by the LLVM Team (L<http://llvm.cs.uiuc.edu>). + +=cut |
