Markus Deuling 20a6ec495b * win32-nat.c (do_win32_fetch_inferior_registers): Use get_regcache_arch
to get at the current architecture and at the target specific vector.
	Add target specific vector to I387_FISEG_REGNUM and I387_FOP_REGNUM and
	remove define of I387_ST0_REGNUM.

	* amd64-tdep.c (I387_ST0_REGNUM): Remove define.

	(amd64_supply_fxsave, amd64_collect_fxsave): Use get_regcache_arch to
	get at the current architecture
	(I387_FISEG_REGNUM, I387_FOSEG_REGNUM): Add target specific vector as
	parameter.

	* i386-tdep.c: Remove various define's and undef's of I387_ST0_REGNUM,
	I387_NUM_XMM_REGS and I387_MM0_REGNUM.

	(I387_NUM_XMM_REGS, I387_XMM0_REGNUM, I387_MXCSR_REGNUM,
	I387_ST0_REGNUM, I387_FCTRL_REGNUM, I387_MM0_REGNUM,
	(I387_FSTAT_REGNUM): Add target specific vector as parameter.

	(i386_register_name, i386_dbx_reg_to_regnum): Use gdbarch_tdep to get
	at the target specific vector.

	(i386_get_longjmp_target): Use get_frame_arch to get at the current
	architecture. Use gdbarch_tdep to get at the target specific vector.

	(i386_fp_regnum_p, i386_fpc_regnum_p): Add gdbarch as parameter and
	update caller. Use gdbarch_tdep to get at the target specific vector.

	(i386_register_to_value: Use get_frame_arch to get at the current
	architecture.

	* i386-tdep.h (i386_fp_regnum_p, i386_fpc_regnum_p): Add gdbarch as
	parameter.

	* i387-tdep.c (I387_FCTRL_REGNUM, I387_FSTAT_REGNUM, I387_FTAG_REGNUM,
	I387_FISEG_REGNUM, I387_FIOFF_REGNUM, I387_FOSEG_REGNUM
	I387_FOOFF_REGNUM, I387_FOP_REGNUM, I387_ST0_REGNUM, FSAVE_ADDR,
	FXSAVE_ADDR, I387_XMM0_REGNUM): Add target specific vector as parameter.

	(I387_ST0_REGNUM, I387_NUM_XMM_REGS): Remove various define's and
	undef's.

	i387_value_to_register): Update call for i386_fp_regnum_p.

	* i387-tdep.h: Remove comment.
