B::Bytecode(3pm)                      Perl Programmers Reference Guide                      B::Bytecode(3pm)



NAME
       B::Bytecode - Perl compiler's bytecode backend

SYNOPSIS
       perl -MO=Bytecode[,-H][,-oscript.plc] script.pl

DESCRIPTION
       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 <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.

KNOWN BUGS
          "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.

NOTICE
       There are also undocumented bugs and options.

       THIS CODE IS HIGHLY EXPERIMENTAL. USE AT YOUR OWN RISK.
