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_convert_register_p, i387_register_to_value, i387_value_to_register): Update call for i386_fp_regnum_p. * i387-tdep.h: Remove comment. (I387_ST0_REGNUM, I387_NUM_XMM_REGS, I387_MM0_REGNUM): Add define. (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_XMM0_REGNUM, I387_MXCSR_REGNUM): Add target specific vector as parameter.
