SECTION
|
||||
Constructors
|
||||
|
||||
Classes in C++ have @dfn{constructors} and @dfn{destructors}. These
|
||||
are functions which are called automatically by the language
|
||||
whenever data of a class is created or destroyed. Class data
|
||||
which is static may also be have a type which requires
|
||||
`construction'; the contructor must be called before the data
|
||||
can be referenced, so the contructor must be called before the
|
||||
program begins.
|
||||
|
||||
The common solution to this problem is for the compiler to
|
||||
call a magic function as the first statement before <<main>>.
|
||||
This magic function (often called <<__main>>) runs around
|
||||
calling the constructors for all the things needing it.
|
||||
|
||||
With COFF, the compiler has a bargain with the linker et al.
|
||||
All constructors are given strange names; for example,
|
||||
<<__GLOBAL__$I$foo>> might be the label of a contructor for
|
||||
the class @var{foo}. The solution on unfortunate systems
|
||||
(most System V machines) is to perform a partial link on all
|
||||
the <<.o>> files, do an <<nm>> on the result, run <<awk>> or some
|
||||
such over the result looking for strange <<__GLOBAL__$>>
|
||||
symbols, generate a C program from this, compile it, and link
|
||||
with the partially linked input. This process is usually
|
||||
called <<collect>>.
|
||||
|
||||
Some versions of <<a.out>> use something called the
|
||||
<<set_vector>> mechanism. The constructor symbols are output
|
||||
from the compiler with a special stab code saying that they
|
||||
are constructors, and the linker can deal with them directly.
|
||||
|
||||
BFD allows applications (i.e., the linker) to deal with
|
||||
constructor information independently of their external
|
||||
implementation by providing a set of entry points for the
|
||||
indiviual object back ends to call to maintain a database
|
||||
of the contructor information. The application can
|
||||
interrogate the database to find out what it wants. The
|
||||
construction data essential for the linker to be able to
|
||||
perform its job are:
|
||||
|
||||
o asymbol -
|
||||
The asymbol of the contructor entry point contains all the
|
||||
information necessary to call the function.
|
||||
|
||||
o table id -
|
||||
The type of symbol, i.e., is it a constructor, a destructor or
|
||||
something else someone dreamed up to make our lives difficult.
|
||||
|
||||
The constructor module takes this information and builds extra
|
||||
sections attached to the BFDs which own the entry points. It
|
||||
creates these sections as if they were tables of pointers to
|
||||
the entry points, and builds relocation entries to go with
|
||||
them so that the tables can be relocated along with the data
|
||||
they reference.
|
||||
|
||||
These sections are marked with a special bit
|
||||
(<<SEC_CONSTRUCTOR>>), which the linker notices and does with
|
||||
what it wants.

DESCRIPTION
|

@var{symbol_ptr_ptr} describes the

function to be called; @var{type} descibes the xtor type,
|
||||
e.g., something like "CTOR" or "DTOR" would be fine. @var{abfd}
|
||||
is the BFD which owns the function. Create a section
|
||||
called "CTOR" or "DTOR" or whatever if the BFD doesn't already
|
||||
have one, and grow a relocation table for the entry points as
|
||||
they accumulate.
|
||||
|
||||
Return <<true>> if successful, <<false>> if out of memory.
