/* The "quick" symbol functions exist so that symbol readers can
avoiding an initial read of all the symbols. For example, symbol
readers might choose to use the "partial symbol table" utilities,
which is one implementation of the quick symbol functions.
The quick symbol functions are generally opaque: the underlying
representation is hidden from the caller.
In general, these functions should only look at whatever special
index the symbol reader creates -- looking through the symbol
tables themselves is handled by generic code. If a function is
defined as returning a "symbol table", this means that the function
should only return a newly-created symbol table; it should not
examine pre-existing ones.
The exact list of functions here was determined in an ad hoc way
based on gdb's history. */
