cpp/utility/basic stacktrace/operator cmp

@1@ Checks if the contents of and  are equal, that is, they have the same number of elements and each element in  compares equal with the element in  at the same position.

@@ Equivalent to.

@2@ Returns the relative order of the numbers of stacktrace entries in and  if they are not equal. Otherwise (if the numbers of elements of and  are equal), returns the lexicographical order of the elements of  and.

@@ Equivalent to.

Return value
@1@ if the contents of  and  are equal,  otherwise.

@2@ if the result is not std, the lexicographical order of the elements of  and  otherwise.

Complexity
@1-2@ Constant if and  are of different size, linear in the size of  otherwise.
