add_exp()

void generator::add_exp

(

rtx

x

)

Add the expansion of X to the encoding.

add_match_operator()

void generator::add_match_operator	(	machine_mode	mode,
		int	opno,
		rtvec	vec )

Add the rtx expansion of a MATCH_OPERATOR or MATCH_OP_DUP.  OPNO is the
number of the matched operand.  MODE is the mode that the rtx should have,
or NUM_MACHINE_MODES if the operand's original mode should be retained.
VEC is the vector of suboperands, which replace those of the original
operand.

add_opcode()

void generator::add_opcode ( expand_opcode opcode )

inline

References add_uint().

Referenced by add_exp(), and add_match_operator().

add_uint()

void generator::add_uint

(

uint64_t

value

)

Add VALUE to the encoding using "BEB128" (big-endian version of LEB128).
This is slightly easier for the consumer.   

References bytes, shift, and value.

Referenced by add_code(), add_exp(), add_match_operator(), add_opcode(), and add_vec().

add_vec()

void generator::add_vec

(

rtvec

vec

)

Add the expansion of rtx vector VEC to the encoding.   

References add_exp(), add_uint(), GET_NUM_ELEM, i, and RTVEC_ELT.

Referenced by add_exp(), and gen_emit_seq().

gen_emit_seq()

const char * generator::gen_emit_seq	(	FILE *	file,
		rtvec	vec )

Output the code necessary for emitting each element of VEC as a separate
instruction.  Return the name of the C++ array that contains the
encoding.   

References add_vec(), and gen_table().

Referenced by gen_expand(), and gen_split().

gen_exp()

const char * generator::gen_exp	(	FILE *	file,
		rtx	x )

Output the code necessary for generating rtx X and return the name
of the C++ array that contains the encoding.   

References add_exp(), and gen_table().

Referenced by gen_expand(), and gen_insn().

gen_table()

const char * generator::gen_table	(	FILE *	file,
		const char *	name )

Emit the encoding as a static C++ array called NAME.  Return NAME.   

References bytes, and i.

Referenced by gen_emit_seq(), and gen_exp().
