=head1 NAME

B::Asmdata - Autogenerated data about Perl ops, used to generate bytecode

=head1 SYNOPSIS

	use B::Asmdata qw(%insn_data @insn_name @optype @specialsv_name);

=head1 DESCRIPTION

Provides information about Perl ops in order to generate bytecode via
a bunch of exported variables.  Its mostly used by B::Assembler and
B::Disassembler.

=over 4

=item %insn_data

  my($bytecode_num, $put_sub, $get_meth) = @$insn_data{$op_name};

For a given $op_name (for example, 'cop_label', 'sv_flags', etc...) 
you get an array ref containing the bytecode number of the op, a
reference to the subroutine used to 'PUT', and the name of the method
used to 'GET'.

=for _private
Add more detail about what $put_sub and $get_meth are and how to use them.

=item @insn_name

  my $op_name = $insn_name[$bytecode_num];

A simple mapping of the bytecode number to the name of the op.
Suitable for using with %insn_data like so:

  my $op_info = $insn_data{$insn_name[$bytecode_num]};

=item @optype

  my $op_type = $optype[$op_type_num];

A simple mapping of the op type number to its type (like 'COP' or 'BINOP').

=item @specialsv_name

  my $sv_name = $specialsv_name[$sv_index];

Certain SV types are considered 'special'.  They're represented by
B::SPECIAL and are referred to by a number from the specialsv_list.
This array maps that number back to the name of the SV (like 'Nullsv'
or '&PL_sv_undef').
