84bdbf814d Fix ia64 code to use the same modular-arithmetic based test to determine whether 
or not a given address is part of a register-backing store.  This test is implemented
by rbs_contains().

Fix and greatly simplify ia64 rbs-switching code.  ia64-test-rbs now passes
100,000 iterations of random testing.

0d0c84f63c (rbs_switch): Rename from rbs_record_switch() and greatly simplify it because 
we now switch to the new backing-store immediately.
(rbs_underflow): Remove.
(rbs_find_stacked): No longer assume that c->bsp is contained in the current
	rbs.  If it is not, first find the backing-store that's backing c->bsp.
(rbs_cover_and_flush): Use rbs_contains() instead of (broken) open code.
	Handle the case where the initial bsp points to an RNaT slot.

Fix unw_resume() some more.  Getting there, slowly.  tests/ia64-test-rbs doesn't
pass fully yet, but it's getting quite far already.

fb1997ff0a Add include of "ia64-test-rbs.h". 
(NELEMS): New macro.
(RECURSION_DEPTH): Fix definition: loadup() allocates 93 local regs, not 95.
(spill_func_t): Make it return an "int".
(DCL): Adjust accordingly.
(verbose): New variable.
(nerrors): Make it an "int".
(unwind_count): Ditto.
(unwind_and_resume): Make it return an int.  Print info-output only if verbose is
	set.  After unwinding to the desired point, redirect IP to
	resumption_point_label and store return value in EH_ARG0 and original
	IP in EH_ARG1.
(run_check): New function.
(main): Remove open test code and call run_check() instead.

(CK_LOC): New macro.
(loadup): ar.pfs is saved in r36, not r34.  After returning from subroutine call,
