36 /* Values can be partially 'optimized out' and/or 'unavailable'.
37  These are distinct states and have different string representations
38  and related error strings.
39 
40  'unavailable' has a specific meaning in this context. It means the
41  value exists in the program (at the machine level), but GDB has no
42  means to get to it. Such a value is normally printed as
43  <unavailable>. Examples of how to end up with an unavailable value
44  would be:
45 
46  - We're inspecting a traceframe, and the memory or registers the
47  debug information says the value lives on haven't been collected.
48 
49  - We're inspecting a core dump, the memory or registers the debug
50  information says the value lives aren't present in the dump
51  (that is, we have a partial/trimmed core dump, or we don't fully
52  understand/handle the core dump's format).
53 
54  - We're doing live debugging, but the debug API has no means to
55  get at where the value lives in the machine, like e.g., ptrace
56  not having access to some register or register set.
57 
58  - Any other similar scenario.
59 
60  OTOH, "optimized out" is about what the compiler decided to generate
61  (or not generate). A chunk of a value that was optimized out does
62  not actually exist in the program. There's no way to get at it
63  short of compiling the program differently.
64 
65  A register that has not been saved in a frame is likewise considered
66  optimized out, except not-saved registers have a different string
67  representation and related error strings. E.g., we'll print them as
68  <not-saved> instead of <optimized out>, as in:
69 
70  (gdb) p/x $rax
71  $1 = <not saved>
72  (gdb) info registers rax
73  rax <not saved>
74 
75  If the debug info describes a variable as being in such a register,
76  we'll still print the variable as <optimized out>. IOW, <not saved>
77  is reserved for inspecting registers at the machine level.
78 
79  When comparing value contents, optimized out chunks, unavailable
80  chunks, and valid contents data are all considered different. See
81  value_contents_eq for more info.

144  object's compile-time type. If the object actually belongs to some
145  class derived from `type', perhaps with other base classes and
146  additional members, then `type' is just a subobject of the real
147  thing, and the full object is probably larger than `type' would
148  suggest.
149 
150  If `type' is a dynamic class (i.e. one with a vtable), then GDB can
151  actually determine the object's run-time type by looking at the
152  run-time type information in the vtable. When this information is
153  available, we may elect to read in the entire object, for several
154  reasons:
155 
156  - When printing the value, the user would probably rather see the
157  full object, not just the limited portion apparent from the
158  compile-time type.
159 
160  - If `type' has virtual base classes, then even printing `type'
161  alone may require reaching outside the `type' portion of the
162  object to wherever the virtual base class has been stored.
163 
164  When we store the entire object, `enclosing_type' is the run-time
165  type -- the complete object -- and `embedded_offset' is the offset
166  of `type' within that larger type, in bytes. The value_contents()
167  macro takes `embedded_offset' into account, so most GDB code
168  continues to see the `type' portion of the value, just as the
169  inferior would.
170 
171  If `type' is a pointer to an object, then `enclosing_type' is a
172  pointer to the object's run-time type, and `pointed_to_offset' is
173  the offset in bytes from the full object to the pointed-to object
174  -- that is, the value `embedded_offset' would have if we followed
175  the pointer and fetched the complete object. (I don't really see
176  the point. Why not just determine the run-time type when you
177  indirect, and avoid the special case? The contents don't matter
178  until you indirect anyway.)
179 
180  If we're not doing anything fancy, `enclosing_type' is equal to
181  `type', and `embedded_offset' is zero, so everything works

514  LENGTH bytes of VAL2's contents starting at OFFSET2.
515 
516  Note that "contents" refers to the whole value's contents
517  (value_contents_all), without any embedded offset adjustment. For
518  example, to compare a complete object value with itself, including
519  its enclosing type chunk, you'd do:
520 
521  int len = TYPE_LENGTH (check_typedef (value_enclosing_type (val)));
522  value_contents_eq (val, 0, val, 0, len);
523 
524  Returns true iff the set of available/valid contents match.
525 
526  Optimized-out contents are equal to optimized-out contents, and are
527  not equal to non-optimized-out contents.
528 
529  Unavailable contente are equal to unavailable contents, and are not
530  equal to non-unavailable contents.
531 
532  For example, if 'x's represent an unavailable byte, and 'V' and 'Z'
533  represent different available/valid bytes, in a value with length
534  16:
535 
536  offset: 0 4 8 12 16
537  contents: xxxxVVVVxxxxVVZZ
538 
539  then:
540 
541  value_contents_eq(val, 0, val, 8, 6) => 1
542  value_contents_eq(val, 0, val, 4, 4) => 0
543  value_contents_eq(val, 0, val, 8, 8) => 0
544  value_contents_eq(val, 4, val, 12, 2) => 1
545  value_contents_eq(val, 4, val, 12, 4) => 0
546  value_contents_eq(val, 3, val, 4, 4) => 0
547 
548  If 'x's represent an unavailable byte, 'o' represents an optimized
549  out byte, in a value with length 8:
550 
551  offset: 0 4 8
552  contents: xxxxoooo
553 
554  then:
555 
556  value_contents_eq(val, 0, val, 2, 2) => 1
557  value_contents_eq(val, 4, val, 6, 2) => 1
558  value_contents_eq(val, 0, val, 4, 4) => 0
559 
560  We only know whether a value chunk is unavailable or optimized out
561  if we've tried to read it. As this routine is used by printing
562  routines, which may be printing values in the value history, long
563  after the inferior is gone, it works with const values. Therefore,
