Field Documentation

enum machine_mode extraction_insn::field_mode

The mode of the field to be inserted or extracted, and by extension the mode of the insertion or extraction itself.

Referenced by simple_mem_bitfield_p(), and widening_optab_handler().

enum insn_code extraction_insn::icode

The code of the instruction.

Referenced by widening_optab_handler().

enum machine_mode extraction_insn::pos_mode

The mode of the field's bit position. This is only important when the position is variable rather than constant.

Referenced by widening_optab_handler().

enum machine_mode extraction_insn::struct_mode

The mode that the structure operand should have. This is byte_mode when using the legacy insv, extv and extzv patterns to access memory.

Referenced by widening_optab_handler().
