=head1 NAME
|
|
|
|
lli - directly execute programs from LLVM bytecode
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
lli [options] [filename] [args ...]
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
B<lli> directly executes programs in LLVM bytecode format. 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.
