B::Bytecode - Perl compiler's bytecode backend
perl -MO=Bytecode[,-H][,-oscript.plc] script.pl
Compiles a Perl script into a bytecode format that could be loaded later by the ByteLoader module and executed as a reg- ular Perl script.
$ perl -MO=Bytecode,-H,-ohi -e 'print "hi!\n"' $ perl hi hi!
-b Save all the BEGIN blocks. Normally only BEGIN blocks that "require" other files (ex. "use Foo;") are saved. -H prepend a "use ByteLoader VERSION;" line to the produced bytecode. -k keep the syntax tree - it is stripped by default. -ooutfile put the bytecode in <outfile> instead of dumping it to STDOUT. -s scan the script for "# line .." directives and for <goto LABEL> expressions. When gotos are found keep the syntax tree.
+ "BEGIN { goto A: while 1; A: }" won't even compile. + "?...?" and "reset" do not work as expected. + variables in "(?{ ... })" constructs are not properly scoped. + scripts that use source filters will fail miserably.
There are also undocumented bugs and options. THIS CODE IS HIGHLY EXPERIMENTAL. USE AT YOUR OWN RISK.
