B::Op_private - OP op_private flag definitions

=head1 SYNOPSIS

    use B::Op_private;

    # flag details for bit 7 of OP_AELEM's op_private:
    my $name  = $B::Op_private::bits{aelem}{7}; # OPpLVAL_INTRO
    my $value = $B::Op_private::defines{$name}; # 128
    my $label = $B::Op_private::labels{$name};  # LVINTRO

    # the bit field at bits 5..6 of OP_AELEM's op_private:
    my $bf  = $B::Op_private::bits{aelem}{6};
    my $mask = $bf->{bitmask}; # etc

=head1 DESCRIPTION

This module provides four global hashes:

    %B::Op_private::bits
    %B::Op_private::defines
    %B::Op_private::labels
    %B::Op_private::ops_using

which contain information about the per-op meanings of the bits in the
op_private field.

=head2 C<%bits>

This is indexed by op name and then bit number (0..7). For single bit flags,
it returns the name of the define (if any) for that bit:

   $B::Op_private::bits{aelem}{7} eq 'OPpLVAL_INTRO';

For bit fields, it returns a hash ref containing details about the field.
The same reference will be returned for all bit positions that make
up the bit field; so for example these both return the same hash ref:

    $bitfield = $B::Op_private::bits{aelem}{5};
    $bitfield = $B::Op_private::bits{aelem}{6};

The general format of this hash ref is

    {
        # The bit range and mask; these are always present.
        bitmin        => 5,
        bitmax        => 6,
        bitmask       => 0x60,

        # (The remaining keys are optional)

        # The names of any defines that were requested:
        mask_def      => 'OPpFOO_MASK',
        baseshift_def => 'OPpFOO_SHIFT',
        bitcount_def  => 'OPpFOO_BITS',

        # If present, Concise etc will display the value with a 'FOO='
        # prefix. If it equals '-', then Concise will treat the bit
        # field as raw bits and not try to interpret it.
        label         => 'FOO',

        # If present, specifies the names of some defines and the
        # display labels that are used to assign meaning to particu-
        # lar integer values within the bit field; e.g. 3 is dis-
        # played as 'C'.
        enum          => [ qw(
                             1   OPpFOO_A  A
                             2   OPpFOO_B  B
                             3   OPpFOO_C  C
                         )],

    };


=head2 C<%defines>

This gives the value of every C<OPp> define, e.g.

    $B::Op_private::defines{OPpLVAL_INTRO} == 128;

=head2 C<%labels>

This gives the short display label for each define, as used by C<B::Concise>
and C<perl -Dx>, e.g.

    $B::Op_private::labels{OPpLVAL_INTRO} eq 'LVINTRO';

If the label equals '-', then Concise will treat the bit as a raw bit and
not try to display it symbolically.

=head2 C<%ops_using>

For each define, this gives a reference to an array of op names that use
the flag.

    @ops_using_lvintro = @{ $B::Op_private::ops_using{OPp_LVAL_INTRO} };
