[rfc] [09/14] Prepare sh targets

["Ulrich Weigand" <uweigand at de dot ibm dot com>]

Hello,

this patch prepares the sh targets by adding REGCACHE arguments to
internal helper routines.

Bye,
Ulrich



ChangeLog:

	* shnbsd-tdep.c (shnbsd_supply_reg): Add REGCACHE parameter, use it
	instead of current_regcache.  Make REGS const.
	(shnbsd_fill_reg): Add REGCACHE parameter; replace current_regcache.
	* shnbsd-tdep.h (shnbsd_supply_reg, shnbsd_fill_reg): Update
	prototypes.
	* shnbsd-nat.c: Include "regcache.h".
	(shnbsd_fetch_inferior_registers): Pass current_regcache to
	shnbsd_supply_reg.
	(shnbsd_store_inferior_registers): Pass current_regcache to
	shnbsd_fill_reg.
	* Makefile.in (shbsd-nat.o): Update dependencies.
