static void gen_insn	(	int	,
		rtx
	)

static

static void gen_insn ( )

static

     Don't mention instructions whose names are the null string
     or begin with '*'.  They are in the machine description just
     to be recognized.

       Emit nothing.

         Write the macro definition, putting \'s at the end of each line,
         if more than one.

References have_error, and message_with_line().

static void gen_macro	(	const char *	,
		int	,
		int
	)

static

Referenced by gen_proto().

static void gen_macro ( )

static

   Print out a wrapper macro for a function which corrects the number
   of arguments it takes.  Any missing arguments are assumed to be at
   the end.

     #define GEN_CALL(A, B, C, D) gen_call((A), (B))

static void gen_proto ( rtx )

static

static void gen_proto ( )

static

   Print out prototype information for a generator function.  If the
   insn pattern has been elided, print out a dummy generator that
   does nothing.

     Many md files don't refer to the last two operands passed to the
     call patterns.  This means their generator functions will be two
     arguments too short.  Instead of changing every md file to touch
     those operands, we wrap the prototypes in macros that take the
     correct number of arguments.

     Some back ends want to take the address of generator functions,
     so we cannot simply use #define for these dummy definitions.

References gen_macro().

int main ( )

     We need to see all the possibilities.  Elided insns may have
     direct calls to their generators in C code.

     Read the machine description.

     Print out the prototypes now.

static void max_operand_1 ( rtx )

static

static void max_operand_1 ( )

static

   Count the number of match_operand's found.

static int num_operands ( rtx )

static

static int num_operands ( )

Variable Documentation

int max_id_len

static

   Max size of names encountered.

int max_opno

static

   Max operand encountered in a scan over some insn.
