  32 =head1 DESCRIPTION
  33
  34 This module provides four global hashes:
  35
  36     %B::Op_private::bits
  37     %B::Op_private::defines
  38     %B::Op_private::labels
  39     %B::Op_private::ops_using
  40
  41 which contain information about the per-op meanings of the bits in the
  42 op_private field.
  43
  44 =head2 C<%bits>
  45
  46 This is indexed by op name and then bit number (0..7). For single bit flags,
  47 it returns the name of the define (if any) for that bit:
  48
  49    $B::Op_private::bits{aelem}{7} eq 'OPpLVAL_INTRO';
  50
  51 For bit fields, it returns a hash ref containing details about the field.
  52 The same reference will be returned for all bit positions that make
  53 up the bit field; so for example these both return the same hash ref:
  54
  55     $bitfield = $B::Op_private::bits{aelem}{5};
  56     $bitfield = $B::Op_private::bits{aelem}{6};
  57
  58 The general format of this hash ref is
  59
  60     {
  61         # The bit range and mask; these are always present.
  62         bitmin        => 5,
  63         bitmax        => 6,
  64         bitmask       => 0x60,
  65
  66         # (The remaining keys are optional)
  67
  68         # The names of any defines that were requested:
  69         mask_def      => 'OPpFOO_MASK',
  70         baseshift_def => 'OPpFOO_SHIFT',
  71         bitcount_def  => 'OPpFOO_BITS',
  72
  73         # If present, Concise etc will display the value with a 'FOO='
  74         # prefix. If it equals '-', then Concise will treat the bit
  75         # field as raw bits and not try to interpret it.
  76         label         => 'FOO',
  77
  78         # If present, specifies the names of some defines and the
  79         # display labels that are used to assign meaning to particu-
  80         # lar integer values within the bit field; e.g. 3 is dis-
  81         # played as 'C'.
  82         enum          => [ qw(
  83                              1   OPpFOO_A  A
  84                              2   OPpFOO_B  B
  85                              3   OPpFOO_C  C
  86                          )],
  87
  88     };
  89
  90
  91 =head2 C<%defines>
  92
  93 This gives the value of every C<OPp> define, e.g.
  94
  95     $B::Op_private::defines{OPpLVAL_INTRO} == 128;
  96
  97 =head2 C<%labels>
  98
  99 This gives the short display label for each define, as used by C<B::Concise>
 100 and C<perl -Dx>, e.g.
 101
 102     $B::Op_private::labels{OPpLVAL_INTRO} eq 'LVINTRO';
 103
 104 If the label equals '-', then Concise will treat the bit as a raw bit and
 105 not try to display it symbolically.
 106
 107 =head2 C<%ops_using>
 108
 109 For each define, this gives a reference to an array of op names that use
 110 the flag.
