Split crtbegin/crtend into crti/crtbegin/crtend/crtn. NetBSD-specific
...
things like the .note.netbsd.ident section are provided by crti/crtn.
crti/crtn also provide the _init() and _fini() routines.
crtbegin/crtend now only provide support for ctors/dtors. This paves
the way to using the "crtstuff" provided with GCC (when we upgrade to
GCC 3.3), which provides, among other things, much better C++/Java
exception handling.

...
SH-5, meet NetBSD.
Let's hope this is the start of a long and fruitful relationship. :-)
This code, funded by Wasabi Systems, adds initial support for the
Hitachi SuperH(tm) SH-5 cpu architecture to NetBSD.
At the present time, NetBSD/evbsh5 only runs on a SH-5 core simulator
which has no simulated devices other than a simple console. However, it
is good enough to get to the "root device: " prompt.
Device driver support for Real SH-5 Hardware is in place, particularly for
supporting the up-coming Cayman evaluation board, and should be quite
easy to get running when the hardware is available.
There is no in-tree toolchain for this port at this time. Gcc-current has
rudimentary SH-5 support but it is known to be buggy. A working toolchain
was obtained from SuperH to facilitate this port. Gcc-current will be
fixed in due course.
The SH-5 architecture is fully 64-bit capable, although NetBSD/evbsh5 has
currently only been tested in 32-bit mode. It is bi-endian, via a boot-
time option and it also has an "SHcompact" mode in which it will execute
SH-[34] user-land instructions.
For more information on the SH-5, see www.superh.com. Suffice to say it
is *not* just another respin of the SH-[34].

Reorganization of crtbegin/crtend.

o Primary mod: alpha and i386 code for .init and .fini section fallthroughs
o Actual fallthru is not yet enabled, see csu/{alpha,i386_elf}/Makefile
o When enabled, should fix bin/12865 & should fix at least one WINE bug,
see http://www.winehq.com/hypermail/wine-devel/2001/05/0021.html
o Also, removed the function pointer hack put in to prevent gcc from
incorrectly attempting to do short calls over section boundaries,
on some architectures, rather, simply simply move ctors() and dtors()
into .init and .fini.
Other notes.
o Our crtbegin.c and crtend.c were completely in C, despite
the fact that .init and .fini section fallthroughs require machine code.
These modules implement the gnu ctors/dtors mechanism directly, eliminating
in part the need for the elf .init/.fini section fallthrough. However,
if we ever want to use the gnu-provided constructor support, we need to
do the fallthrough, at least one program (WINE) apparently uses the
feature independently, and other compilers may depend on the mechanism.
o It is amusing that the previous NetBSD _init() and _fini() were put
into the .init and .fini sections, because nothing is gained over
plain .text if they don't fall through. Cargo cult!
o Other elf ports will need to copy the alpha and i386 example mods.
