Detailed Description

token type struct

Only defines data members to clean up the dependency graph

Definition in file token_t.h.

Data Structure Documentation

struct Token.instr

instruction data. Not used if token type is not TT_INSTR

Definition at line 43 of file token_t.h.

Data Fields
int	address	address of instruction in resulting bytecode
enum AddressMode	addressmode	Address mode of the instruction.
Instruction *	inst	pointer to instruction data
int	number	operand of the instruction

struct Token.source

source of this token

Definition at line 59 of file token_t.h.

Data Fields
char	fname[TOKEN_SOURCE_FILE_SIZE]	file name of source file
int	lineno	line in source file

anonymous enum

Enumerator
OPC_INVALID	An invalid opcode to signal invalid / non-existent variations.
MAP_MAX_KEY_LEN	Key buffer size for Map.
NUMBER_ERROR	Could not parse a number or constant is undefined.
NUMBER_LABEL_NODEF	Undefined label.
STATE_MAX_STRING_LEN	max string length for input/output files
TOKEN_BUFFER_SIZE	Token max length.
TOKEN_SOURCE_FILE_SIZE	source filename max length. Longer strings will get truncated.
