ext::B::B::BytecoPerlpProgrammers Referencext::B::B::Bytecode(3p)NAMEB::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 reg-
ular 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.
