B::Bytecode \- Perl compiler's bytecode backend
\&\fBperl \-MO=Bytecode\fR[\fB,\-H\fR][\fB,\-o\fR\fIscript.plc\fR] \fIscript.pl\fR
Compiles a Perl script into a bytecode format that could be loaded
later by the ByteLoader module and executed as a regular Perl script.
\& $ perl -MO=Bytecode,-H,-ohi -e 'print "hi!\en"'
Save all the \s-1BEGIN\s0 blocks. Normally only \s-1BEGIN\s0 blocks that \f(CW\*(C`require\*(C'\fR
other files (ex. \f(CW\*(C`use Foo;\*(C'\fR) are saved.
prepend a \f(CW\*(C`use ByteLoader VERSION;\*(C'\fR line to the produced bytecode.
keep the syntax tree \- it is stripped by default.
.IP "\fB\-o\fR\fIoutfile\fR" 4
put the bytecode in <outfile> instead of dumping it to \s-1STDOUT\s0.
scan the script for \f(CW\*(C`# line ..\*(C'\fR directives and for <goto \s-1LABEL\s0>
expressions. When gotos are found keep the syntax tree.
\&\f(CW\*(C`BEGIN { goto A: while 1; A: }\*(C'\fR won't even compile.
\&\f(CW\*(C`?...?\*(C'\fR and \f(CW\*(C`reset\*(C'\fR do not work as expected.
variables in \f(CW\*(C`(?{ ... })\*(C'\fR constructs are not properly scoped.
scripts that use source filters will fail miserably.
There are also undocumented bugs and options.
