NAME
B::Bytecode - Perl compiler's bytecode backendSYNOPSIS
perl -MO=Bytecode[,-H][,-oscript.plc] script.plDESCRIPTION
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.
