a50163af65 Build separate crt{begin,end}.o and crt{begin,end}S.o files, rather 
than linking them at install time.  Forthcoming changes require different
behavior for static vs. shared object versions of these files.

c41160abff Add support for registering Java classes emitted by the Java compiler

f768a5c42b Reduce the alignment constraint from 4 to 2. This fixes the problem where 
gas(2) pads the text segment with 0x0 instead of NOP. Since m68k instructions
only need 16-bit alignment, .align 2 works just fine.

9a68629ca6 Enlarge the stack frame to 16 bytes, and store the return address 8 
bytes in instead of at the start, to leave room for a .cpload to store
the gp at offset 0 in the frame.  Allow 8 bytes for each (for mips64
one day...).

.cpload overwrite problems noted by Michael Hitch.

ee6a16ad18 Add a secondary label called __start (makes gcc 2.95.3 happier) and rename 
the internal __start to ___start.   (Since -e is not supplied by default,
this has no effect on a native build.)

2d62241cb9 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.

ps_strings pointer. Use assembly to get argc, argv and argp and then
call __start().

ab2c05e5a3 Eliminate incorrect gcc-generated cross-section bsr's by calling the static 
constructor/destructor dispatcher via a function pointer protected from
constant propagation. Also, create (presently unused) .S files that solve
the same problem and in addition allow in-line .init section and .fini
section code. This is too big a mod for a 3.2 pullup, however.

can see the hand assembly mods in a cvs diff rather than having to start over
from the prototype .c files. (Although these will also be available.)
