[PATCH/RFC] Get Alpha target to GDB_MULTI_ARCH_PARTIAL

[Jason R Thorpe <thorpej at wasabisystems dot com>]

Folks...

Attached is a patch that gets the Alpha target to GDB_MULTI_ARCH_PARTIAL.
This is the low-hanging fruit.

I'm a little troubled by the apparent state of the Alpha target.  While
my patch results in fewer testsuite failures, the number of failures still
seems quite high.

With the alpha-netbsd target I posted here a while ago:

Before:
                === gdb Summary ===

# of expected passes            6340
# of unexpected failures        1187
# of unexpected successes       2
# of expected failures          145
# of unresolved testcases       138
# of unsupported tests          3


After:
                === gdb Summary ===

# of expected passes            6595
# of unexpected failures        945
# of unexpected successes       4
# of expected failures          143
# of unresolved testcases       118
# of untested testcases         6
# of unsupported tests          3

I would really like to know what the test results are on Digital Unix
or Linux (I can't easily install either of those on any of my Alpha
systems, unfortunately).

I'd really appreciate a sanity check on this patch.  Some of the
subtleties of e.g. the call_dummy stuff elude me, and this is related
to some of the testsuite failures (both before and after).

	* Makefile.in (alpha-nat.o): Add alpha-tdep.h to dependency list.
	(alpha-tdep.o): Likewise.
	* alpha-nat.c: Include alpha-tdep.h.  Update for adjusted
	Alpha target register names.
	* alphabsd-nat.c: Likewise.
	* alpha-tdep.c: Include alpha-tdep.h.  Update for adjusted
	Alpha target register names.  Make serveral routines static.
	(alpha_gdbarch_init): New function.
	(_initialize_alpha_tdep): Register alpha_gdbarch_init.
	* alpha-tdep.h: New file.  Includes several Alpha target constants
	taken from...
	* config/alpha/tm-alpha.h: ...here.  Remove macros that we now
	let gdbarch deal with.
	(GDB_MULTI_ARCH): Define as GDB_MULTI_ARCH_PARTIAL.
