Detailed Description

Structure containing all the values that might be found in a source line. The contents of this structure are set during pass_one() and used to build the 16 bit instruction during pass_two. This is only used in assembler.c, but is declared here for documentation purposes.

Field Documentation

int line_info::address

LC3 address of instruction

int line_info::DR

DR or SR, if present (bits 11..9)

inst_format_t* line_info::format

name/operands/prototype for instruction

int line_info::immediate

Immediate value, if present

int line_info::lineNum

Line number in source code

line_info_t* line_info::next

Allow for linked list

opcode_t line_info::opcode

opcode of instruction (bits 15..13)

char* line_info::reference

Label referenced by instruction, if any

int line_info::SR1

SR1 or BaseR, if present (bits 8..6)

int line_info::SR2

SR2, if present (bits 2..0)
