unsigned int operand_alternative::anything_ok

     Nonzero if 'X' was found in the constraint string, or if the constraint
     string for this alternative was empty.

Referenced by extract_insn(), finish_insn_recog_data(), and process_alt_operands().

enum reg_class operand_alternative::cl

     The register class valid for this alternative (possibly NO_REGS).

Referenced by build_def_use(), copyprop_hardreg_forward_1(), and replace_src_with_reg_ok_p().

const char* operand_alternative::constraint

     Pointer to the beginning of the constraint string for this alternative,
     for easier access by alternative number.

Referenced by process_alt_operands().

unsigned int operand_alternative::decmem_ok

     Nonzero if '<' was found in the constraint string.

unsigned int operand_alternative::earlyclobber

     Nonzero if '&' was found in the constraint string.

unsigned int operand_alternative::incmem_ok

     Nonzero if '>' was found in the constraint string.

unsigned int operand_alternative::is_address

     Nonzero if 'p' was found in the constraint string.

int operand_alternative::matched

     The same information, but reversed: -1 if this operand is not
     matched by any other, or the operand number of the operand that
     matches this one.

int operand_alternative::matches

     -1 if no matching constraint was found, or an operand number.

Referenced by build_def_use(), copyprop_hardreg_forward_1(), and replace_src_with_reg_ok_p().

unsigned int operand_alternative::memory_ok

     Nonzero if TARGET_MEM_CONSTRAINT was found in the constraint
     string.

unsigned int operand_alternative::nonoffmem_ok

     Nonzero if 'V' was found in the constraint string.

unsigned int operand_alternative::offmem_ok

     Nonzero if 'o' was found in the constraint string.

unsigned int operand_alternative::reject

     "Badness" of this alternative, computed from number of '?' and '!'
     characters in the constraint string.

Referenced by reg_in_class_p().
