Ulrich Weigand 28f5035f33 * mips-linux-tdep.c (supply_32bit_reg): Add REGCACHE parameter. Use it
instead of current_regcache.
	(mips_supply_gregset): Likewise.  Pass REGCACHE to supply_32bit_reg.
	Make GREGSETP const, remove superfluous casts.
	(mips_fill_gregset): Add REGCACHE parameter; replace current_regcache.
	(mips_supply_fpregset): Likewise.  Make FPREGSETP const, remove
	superfluous casts.
	(mips_fill_fpregset): Add REGCACHE parameter; replace current_regcache.
	(supply_64bit_reg): Likewise
	(mips64_supply_gregset): Likewise.  Pass REGCACHE to supply_64bit_reg.
	Make GREGSETP const, adapt casts accordingly.
	(mips64_fill_gregset): Add REGCACHE parameter; replace current_regcache.
	(mips64_supply_fpregset): Likewise.  Make FPREGSET const, adapt
	casts accordingly.
	(mips64_fill_fpregset): Add REGCACHE parameter; replace current_regcache.
	(fetch_core_registers): Pass current_regcache to mips{64}_(supply|fill)_
	helper routines.
	* mips-linux-tdep.h (mips_supply_gregset, mips_fill_gregset,
	mips_supply_fpregset, mips_fill_fpregset, mips64_supply_gregset,
	mips64_fill_gregset, mips64_supply_fpregset, mips64_fill_fpregset):
	Adapt prototypes.
	* mips-linux-nat.c: Include "regcache.h".
	(supply_gregset, fill_gregset, supply_fpregset, fill_fpregset): Pass
	current_regcache to mips{64}_(supply|fill)_ helper routines.
	(mips64_linux_regsets_fetch_registers): Likewise.
	(mips64_linux_regsets_store_registers): Likewise.

	* mipsnbsd-tdep.c (mipsnbsd_supply_reg, mipsnbsd_supply_fpreg): Add
	REGCACHE argument; replace current_regcache.  Make REGS const.
	(mipsnbds_fill_reg, mipsnbsd_fill_fpreg): Add REGCACHE argument;
	replace current_regcache.
	* mipsnbsd-tdep.h (ipsnbsd_supply_reg, mipsnbsd_supply_fpreg,
	mipsnbds_fill_reg, mipsnbsd_fill_fpreg): Adapt prototypes.
	* mipsnbsd-nat.c (mipsnbsd_fetch_inferior_registers,
	mipsnbsd_store_inferior_registers): Pass current_regcache to
	mipsnbsd_(supply|fill)_... helper routines.

	* Makefile.in (mips-linux-nat.o): Update dependencies.
