Value Annotations have been removed. gdb/mi instead provides Variable Objects.
^Z^Zvalue-history-begin history-number value-flags history-string ^Z^Zvalue-history-value the-value ^Z^Zvalue-history-end
where history-number is the number it is getting in the value history, history-string is a string, such as $5 = , which introduces the value to the user, the-value is the output corresponding to the value itself, and value-flags is * for a value which can be dereferenced and - for a value which cannot.
^Z^Zvalue-begin value-flags the-value ^Z^Zvalue-end
^Z^Zarg-begin argument-name ^Z^Zarg-name-end separator-string ^Z^Zarg-value value-flags the-value ^Z^Zarg-end
where argument-name is the name of the argument,
separator-string is text which separates the name from the value
for the user's benefit (such as =), and value-flags and
the-value have the same meanings as in a
^Z^Zfield-begin value-flags field-name ^Z^Zfield-name-end separator-string ^Z^Zfield-value the-value ^Z^Zfield-end

is text which separates the name from the value for the user's benefit
(such as =), and value-flags and the-value have the

When printing an array, gdb annotates it as follows:
^Z^Zarray-section-begin array-index value-flags
where array-index is the index of the first element being
annotated and value-flags has the same meaning as in a
value-history-begin annotation. This is followed by any number
of elements, where is element can be either a single element:
, whitespace ; omitted for the first element the-value ^Z^Zelt
or a repeated element
, whitespace ; omitted for the first element the-value ^Z^Zelt-rep number-of-repetitions repetition-string ^Z^Zelt-rep-end
In both cases, the-value is the output for the value of the element and whitespace can contain spaces, tabs, and newlines. In the repeated case, number-of-repetitions is the number of consecutive array elements which contain that value, and repetition-string is a string which is designed to convey to the user that repetition is being depicted.
