-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.

-SYNOPSIS
- boolean bfd_constructor_entry(bfd *abfd,

-
-
-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.
