[PATCH RFA] Create new file mips-tdep.h

[PATCH RFA] Create new file mips-tdep.h

[Kevin Buettner]

I have some other changes under way in which I will need to know which
mips ABI is in use.  I've moved struct gdbarch_tdep and the enums
that it depends upon into a new header file.

Okay?

	* Makefile.in (mips_tdep_h): Define.
	(mips-tdep.o): Remove osabi_h from dependency list.  Add mips_tdep_h
	to dependency list.
	* mips-tdep.h: New file.
	* mips-tdep.c (mips-tdep.h): Include.
	(osabi.h): Don't include (since it's included by mips-tdep.h).
	(enum mips_abi, enum_mips_fpu_type, struct gdbarch_tdep): Move
	definitions to mips-tdep.h.

I think this is a good idea, though of course you'll need to wait for
Andrew - it may be some time, I believe.

This patch reminded me of something.  I don't really like the fact that
we have a "struct gdbarch_tdep" for every architecture; when we have a
multi-architecture GDB this will cause tremendous debugging confusion. 
How intrusive do you think it would be to opaquify it (I hope that's
not really a word) properly, and have a struct mips_gdbarch_tdep?

Can you expand on this?  Where, outside of mips-tdep.c will this be needed?

Well, I've got a patch which depends on Kevin's, in which I need to get
at the tdep information in mips-linux-tdep.c.  That's signal frame
support... it was quite a hassle to get it working :)

Yep, mips-linux-tdep.c is where I need it too.

Rather than publishing `struct gdbarch_tdep', can you instead just 
publish accessor methods for the parts you need?  Otherwize ok.

Okay, I've just committed the patch below.  I have some WIP patches
to mips-linux-tdep.c which use mips_abi().

	* Makefile.in (mips_tdep_h): Define.
	(mips-tdep.o): Add mips_tdep_h to dependency list.
	* mips-tdep.h: New file.
	* mips-tdep.c (mips-tdep.h): Include.
	(enum mips_abi): Move to mips-tdep.h.
	(mips_abi): New function.
