Field Documentation

rtx comparison::in_a

     The two values being compared.  These will be either REGs or
     constants.  

rtx comparison::in_b

bool comparison::inputs_valid

     True if its inputs are still valid at the end of the block.  

rtx comparison::insn

     The comparison instruction.  

bool comparison::missing_uses

     True if not all uses of this comparison have been identified.
     This can happen either for overflowing the array above, or if
     the flags register is used in some unusual context.  

unsigned short comparison::n_uses

     The number of uses identified for this comparison.  

enum machine_mode comparison::orig_mode

     The original CC_MODE for this comparison.  

rtx comparison::prev_clobber

     The insn prior to the comparison insn that clobbers the flags.  

struct comparison_use comparison::uses[MAX_CMP_USE]

     Information about how this comparison is used.
