=head1 Bootstrapping procedure for nqp-rx NPQ-rx is a bootstrapped compiler, which means that it uses itself to compile itself. To make the first compilation possible, a compiled version of the compiler is stored in F</src/stage0/*.pir> and included in the source code repository. Also the parrot virtual machine ships the same C<stage0/*.pir> files. When you make changes to the compiler, eventually you need to update these I<stage0> files. Here is how you proceed to update the bootstrapping files nqp-rx and parrot. At any stage, if C<make test> fails, don't go ahead with the following steps, but fix the problem first. =over =item * Make your changes, run C<make test> =item * Run C<make bootstrap-files> and C<make test> =item * Commit the non-bootstrap files that you modified yourself =item * Commit the bootstrap files =item * Copy the I<stage0> files over to parrot: cp src/stage0/*.pir $PARROT_SRC/ext/nqp-rx/src/stage0 =item * In the parrot source, run C<make test> and commit =back References: L<http://irclog.perlgeek.de/perl6/2010-04-22#i_2253227>
