multiple times and yields multiple .o files.
This file is useful on target machines where the object file format
supports multiple "user-defined" sections (e.g. COFF, ELF, ROSE). On
such systems, this file allows us to avoid running collect (or any
other such slow and painful kludge). Additionally, if the target
system supports a .init section, this file allows us to support the
linking of C++ code with a non-C++ main program.
Note that if INIT_SECTION_ASM_OP is defined in the tm.h file, then
this file *will* make use of the .init section. If that symbol is
not defined however, then the .init section will not be used.
1992-06-05 03:12:25 +08:00
Currently, only ELF and COFF are supported. It is likely however that
ROSE could also be supported, if someone was willing to do the work to
make whatever (small?) adaptations are needed. (Some work may be
needed on the ROSE assembler and linker also.)

/* We do not want to add the weak attribute to the declarations of these
routines in unwind-dw2-fde.h because that will cause the definition of
these symbols to be weak as well.
This exposes a core issue, how to handle creating weak references vs
how to create weak definitions. Either we have to have the definition
of TARGET_WEAK_ATTRIBUTE be conditional in the shared header files or
have a second declaration if we want a function's references to be weak,
but not its definition.
Making TARGET_WEAK_ATTRIBUTE conditional seems like a good solution until
one thinks about scaling to larger problems -- i.e., the condition under
which TARGET_WEAK_ATTRIBUTE is active will eventually get far too
complicated.
So, we take an approach similar to #pragma weak -- we have a second
declaration for functions that we want to have weak references.
Neither way is particularly good. */

/* Some systems place the number of pointers in the first word of the
table. On SVR4 however, that word is -1. In all cases, the table is
null-terminated. On SVR4, we start from the beginning of the list and
invoke each per-compilation-unit destructor routine in order
until we find that null.
Note that this function MUST be static. There will be one of these
functions in each root executable and one in each shared library, but
although they all have the same code, each one is unique in that it
refers to one particular associated `__DTOR_LIST__' which belongs to the
same particular root executable or shared library file.
On some systems, this routine is run more than once from the .fini,
when exit is called recursively, so we arrange to remember where in
the list we left off processing, and we resume at that point,
should we be re-invoked.
This routine does not need to be run if none of the following clauses are
true, as it will not do anything, so can be removed. */

may be performed by the code in the .init section contributions made by
other libraries, etc. That's because those other initializations may
include setup operations for very primitive things (e.g. initializing
