/* This file is a bit like libgcc2.c in that it is compiled
|
1992-03-07 05:32:07 +01:00
|
|
|
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.
|
|
|
|
|
|
1992-06-04 21:12:25 +02:00
|
|
|
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
|
2001-03-28 13:04:51 +02:00
|
|
|
routines in unwind-dw2-fde.h because that will cause the definition of
|
|
|
|
|
these symbols to be weak as well.
|
1999-02-27 23:21:58 +01:00
|
|
|
|
|
|
|
|
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
|
alias.c, [...]: Fix comment typos.

one thinks about scaling to larger problems -- i.e., the condition under
|
1999-02-27 23:21:58 +01:00
|
|
|
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. */

function epilogue at the very end of the .init section for this

|
entire root executable file or for this entire shared library file.
|
|
|
|
|
|
|
|
|
|
Note that we use some tricks here to get *just* the body and just
|
|
|
|
|
a function epilogue (but no function prologue) into the .init
|
1995-05-16 14:39:54 +02:00
|
|
|
section of the crtend.o file. Specifically, we switch to the .text
|
1994-11-19 05:09:58 +01:00
|
|
|
section, start to define a function, and then we switch to the .init
|
|
|
|
|
section just before the body code.
|
|
|
|
|
|
|
|
|
|
Earlier on, we put the corresponding function prologue into the .init
|
|
|
|
|
section of the crtbegin.o file (which will be linked in first).
|
|
|
|
|
|
|
|
|
|
Note that we want to invoke all constructors for C++ file-scope static-
|
|
|
|
|
storage objects AFTER any other possible initialization actions which
|
|
|
|
|
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
|
|
|
|
|
the state of the floating-point coprocessor, etc.) which should be done
|
1996-07-04 00:07:53 +02:00
|
|
|
before we start to execute any of the user's code. */
