/* 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. */

Convert quick_symbol_functions to use methods
This changes quick_symbol_functions to be a base class with pure
virtual methods, rather than a struct holding function pointers.
Then, objfile is changed to hold a unique_ptr to an instance of this
class.
struct psymbol_functions is put into psympriv.h, and not psymtab.c,
because that is convenient later in the series.

Convert quick_symbol_functions to use methods
This changes quick_symbol_functions to be a base class with pure
virtual methods, rather than a struct holding function pointers.
Then, objfile is changed to hold a unique_ptr to an instance of this
class.
struct psymbol_functions is put into psympriv.h, and not psymtab.c,
because that is convenient later in the series.

FILE_MATCHER is called for each file in OBJFILE. The file name

skipped. If FILE_MATCHER is NULL the file is not skipped. If

part).

the symbol table is expanded.

If KIND does not match, the symbol is skipped.

Convert quick_symbol_functions to use methods
This changes quick_symbol_functions to be a base class with pure
virtual methods, rather than a struct holding function pointers.
Then, objfile is changed to hold a unique_ptr to an instance of this
class.
struct psymbol_functions is put into psympriv.h, and not psymtab.c,
because that is convenient later in the series.
