+ Based on a previous patch form Michal Ludvig:
+ * amd64-tdep.c (amd64_sse_type): Remove.
+ (amd64_register_info): Use i386_eflags_type and i386_sse_type
+ where appropriate.
+ (AMD64_NUM_REGS): Use ARRAY_SIZE.
+ (amd64_register_type): Remove code to build amd_sse_type.
+ * i386-tdep.c (i386_eflag_type): New variable.
+ (i386_mmx_type, i386_sse_type): Make global.
+ (i386_init_types): New function.
+ (i386_build_mmx_type, i386_build_sse_type): Remove functions.
+ (i386_register_type): Return i386_eflag_type, i386_sse_type and
+ i386_mmx_type when appropriate.
+ (_initialize_i386_tdep): Call i386_init_types.
+ * i386-tdep.h (i386_eflags_type, i386_mmx_type, i386_sse_type):
+ Declare extern.
+
Based on a previous patch form Michal Ludvig:
* gdbtypes.c (append_flags_type_flag, init_flags_type): New
functions.
