Support x86 pseudo byte, word and dword registers. gdb/ 2010-03-02 H.J. Lu <hongjiu.lu@intel.com> * amd64-tdep.c (amd64_byte_names): New. (amd64_word_names): Likewise. (amd64_dword_names): Likewise. (amd64_pseudo_register_name): Likewise. (amd64_pseudo_register_read): Likewise. (amd64_pseudo_register_write): Likewise. (amd64_init_abi): Set num_byte_regs, num_word_regs, num_dword_regs and num_mmx_regs. Call set_gdbarch_pseudo_register_read, set_gdbarch_pseudo_register_write and set_tdesc_pseudo_register_name. Don't call set_gdbarch_num_pseudo_regs. Don't set mm0_regnum. * i386-tdep.c (i386_num_mmx_regs): Removed. (i386_num_pseudo_regs): Likewise. (i386_byte_names): New. (i386_word_names): Likewise. (i386_byte_regnum_p): Likewise. (i386_word_regnum_p): Likewise. (i386_mmx_regnum_p): Updated. (i386_pseudo_register_name): Make it global. Handle byte and word pseudo-registers. (i386_pseudo_register_read): Likewise. (i386_pseudo_register_write): Likewise. (i386_pseudo_register_type): Handle byte, word and dword pseudo-registers (i386_register_reggroup_p): Don't include pseudo registers, except for MXX, in any register groups. Don't include pseudo byte, word, dword registers in general_reggroup. (i386_gdbarch_init): Set num_byte_regs, num_word_regs, num_dword_regs, al_regnum, ax_regnum and eax_regnum. Put MMX pseudo-registers after word pseudo-registers. Call set_gdbarch_num_pseudo_regs after calling gdbarch_init_osabi. * i386-tdep.h (gdbarch_tdep): Add num_mmx_regs, num_byte_regs, al_regnum, num_word_regs, ax_regnum, num_dword_regs and eax_regnum. (i386_byte_regnum_p): New. (i386_word_regnum_p): Likewise. (i386_dword_regnum_p): Likewise. (i386_pseudo_register_name): Likewise. (i386_pseudo_register_read): Likewise. (i386_pseudo_register_write): Likewise. gdb/testsuite/ 2010-03-02 H.J. Lu <hongjiu.lu@intel.com> * gdb.arch/amd64-byte.exp: New. * gdb.arch/amd64-dword.exp: Likewise. * gdb.arch/amd64-pseudo.c: Likewise. * gdb.arch/amd64-word.exp: Likewise. * gdb.arch/i386-byte.exp: Likewise. * gdb.arch/i386-pseudo.c: Likewise. * gdb.arch/i386-word.exp: Likewise.
