100e0d5e7e From the 2.8 tree:
(find_dummy_reload): New parameter earlyclobber.  If set then don't
use IN for the reload if it also appears elsewhere in the insn.  All
callers changed.

This fixes problems compiling editors/emacs and games/abuse on the Shark.

7884b51fe1 From David Edelsohn, via the GCC 2.8 development sources:
* loop.c (combine_movables): Earlier insns don't match later ones.
This fixes compilation problems with sa(1) and pkgsrc/games/abuse.

b2b8303852 C++ support changes:
Generate .ctors and .dtors sections which contain the contructor and
deconstructor function addresses.

Use .init and .fini sections to call the functions to call those functions.

Include the crtbegin and crtend object files which perform those calls.

6a93608a3d ns32k.c:
* ns32k_gen_operand is no longer needed.
* new function symbolic_reference_mentioned_p (stolen from i386).
* make print_operand dtrt when printing symbolic "constants" in picmode
  and abort for the cases that it can't handle (e.g. symbol+offset).

ns32k.h:
* Use NS32K_DISPLACEMENT_P wherever suitable.
* make LEGITIMATE_PIC_OPERAND_P dtrt to make the ns32k_gen_operand hack
  unnecessary.

ns32k.md:
* Use general_operand instead of ns32k_gen_operand everywhere.
* replace "rmn" by "g" again.
* make addsi3 dtrt for pic.

The comments in ns32k.md still need some updates.
Thank's again to Ian Dall for his help.
