Function Documentation

static bool check_tune_attr ( )
   Check that attribute NAME is used in define_insn_reservation condition
   EXP.  Return true if it is.  

Referenced by find_tune_attr().

static bool find_tune_attr ( )
   Try to find a const attribute (usually cpu or tune) that is used
   in all define_insn_reservation conditions.

static void gen_attr ( )
     If numeric attribute, don't need to write an enum.  
     If `length' attribute, write additional function definitions and define
     variables used by `insn_current_length'.  
int main ( )
     Read the machine description.  
         Output interface for pipeline hazards recognition based on
         DFA (deterministic finite state automata.  
         Interface itself: 
         Otherwise we do no scheduling, but we need these typedefs
         in order to avoid uglifying other code with more ifdefs.  
     Special-purpose attributes should be tested with if, not #ifdef.  
     We make an exception here to provide stub definitions for
     insn_*_length* / get_attr_enabled functions.  
     Output flag masks for use by reorg.
