B::Bytecode 5.8.8

B::Bytecode is Perl compilers bytecode backend.

SYNOPSIS

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 regular Perl script.

EXAMPLE

$ perl -MO=Bytecode,-H,-ohi -e print "hi!n"
$ perl hi
hi!

OPTIONS

-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 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.
