This should not be used directly for building host tools; rather, the top
level bootstrap (to be committed separately) should be used to build the
entire system including this compiler.
GC all of the backward branch code (which wasn't used).
Separate the a.out stuff into a separate .h file.
Some other random cleanup.
Leave the arm_preserved_register() hack for now.
(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.
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.
* 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.
This commits several enhancements done over the last years:
- adddi3 subdi3 insn definitions: Jon Buller (ns32k.md, ns32k.c)
- ffssi2 adddi3 and subdi3 bug fixes: Matthias Pfaller (ns32k.c, ns32k.md)
- movstrsi reimplimentation: Ian Dall (ns32k.c, ns32k.md, ns32k.h)
- 32381 fpu support (extra registers, multiply - add instructions):
Ian Dall (ns32k.c, ns32k.h, ns32k.md)
- divmoddisi: (re) implimentation Ian Dall (ns32k.md)
- use predicate rather than register constraints to allow better code for
non pic case: Ian Dall (ns32k.md, ns32k.c)
- clean up of many macros in ns32k.h: Ian Dall
command line. This behaviour is how it's documented; it should work
that way. Also fixes building a release tree on a -current system (which
bit me with the sparc secr set I built for pk).
