| 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(), and copyprop_hardreg_forward_1().
| 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(), and copyprop_hardreg_forward_1().
| 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.
