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 ^

-H

prepend a use ByteLoader VERSION; line to the produced bytecode.

-b

Save all the BEGIN blocks. Normally only BEGIN blocks that require other files (ex. use Foo;) are saved.

-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.

-S

Output assembler source rather than piping it through the assembler and outputting bytecode. Without -q the assembler source is commented.

-q

Be quiet.

-DM

Set debugging flag for more verbose STDERR output.

M for Magic and Matches.
