Member Data Documentation

◆ instruction

fcml_en_instruction fcml_st_instruction_details::instruction

Instruction code/number.

See also: fcml_instructions.h header file.

◆ is_pseudo_op

fcml_bool fcml_st_instruction_details::is_pseudo_op

True if a given instruction is a short form of pseudo-ops instructions.

See 'vcmpunordsd' for instance.

◆ is_shortcut

fcml_bool fcml_st_instruction_details::is_shortcut

True if this is a shortcut.

A good example of such instruction is 'cmpsb' as opposed to 'cmps byte ptr [si],byte ptr [di]'. It is very important to take this information into consideration when instruction models are analyzed because there are no operands available in the GIM in case of such shortcuts.

◆ opcode_field_s_bit

fcml_bool fcml_st_instruction_details::opcode_field_s_bit

Opcode field 's'.

This is set only for informational purpose only and you should not use it for any critical functionality.

◆ opcode_field_w_bit

fcml_bool fcml_st_instruction_details::opcode_field_w_bit

Opcode field 'w'.
