Typedefs | |
typedef xed_flag_enum_s | xed_flag_action_t |
Associated with each flag field there can be one action. | |
typedef xed_simple_flag_s | xed_simple_flag_t |
A collection of xed_flag_action_t's and unions of read and written flags. |
The flags are available from the xed_decoded_inst_t via the xed_decoded_inst_get_rflags_info() function which returns a xed_simple_flag_t pointer.
The type xed_flag_set_t keeps the integer flags in the order specified by the RFLAGS register. The x87 flags are stored in the most signficant 4 bits of the flag set. This should not affect use by the normal integer operations; Those bits are reserved as zero in the RFLAGS.
