Ulrich Weigand 390c15228a * alpha-tdep.c (alpha_supply_int_regs, alpha_fill_int_regs,
alpha_supply_fp_regs, alpha_fill_fp_regs): Add REGCACHE parameter,
	use it instead of current_regcache.
	* alpha-tdep.h (struct regcache): Add forward declaration.
	(alpha_supply_int_regs, alpha_fill_int_regs, alpha_supply_fp_regs,
	alpha_fill_fp_regs): Update prototypes.

	* alpha-nat.c: (supply_gregset, fill_gregset, supply_fpregset,
	fill_fpregset): Pass current_regcache to alpha_supply/fill_ routines.
	* alpha-linux-nat.c: Include "regcache.h".
	(supply_gregset, fill_gregset, supply_fpregset, fill_fpregset): Pass
	current_regcache to alpha_supply/fill_ routines.

	* alphabsd-tdep.c: Include "regcache.h".
	(alphabsd_supply_reg, alphabsd_supply_fpreg): Add REGCACHE paramter,
	pass it to alpha_supply_ routines.  Make REGS const.
	(alphabsd_fill_reg, alphabsd_fill_fpreg): Add REGCACHE parameter,
	pass it to alpha_fill_ routines.
	* alphabsd-tdep.h (struct regcache): Add forward declaration.
	(alphabsd_supply_reg, alphabsd_fill_reg, alphabsd_supply_fpreg,
	alphabsd_fill_fpreg): Update prototypes.

	* alphanbsd-nat.c (supply_gregset, fill_gregset, supply_fpregset,
	fill_fpregset, alphabsd_fetch_inferior_registers,
	alphabsd_store_inferior_registers): Pass current_regcache to
	alphabsd_supply/fill_ routines.

	* Makefile.in (alpha-linux-nat.o, alphabsd-tdep.o): Update
	dependencies.
